In Tulsa, there are up to 1500m of well-layered sedimentary rocks. (About 100 layers)

 

Basement rocks = unproductive rocks = igneous and metamorphic rocks = very old rocks

 

When drilling encounters base rock, the drilling is usually stopped.

 

A Shield area= basement rocks exposed to the surface (no sediment rocks) => such as Canadian Shield in eastern Canada, tends to be a large low-lying area. Ore minerals such as iron, copper, lead, zinc, gold and silver are mined from the basement rock in shield areas.

 

Basin = sedimentary rocks are very thick. The Caspian basin has about 26km sedimentary rock cover. Most gas and oil is found and produced from the sedimentary rock basins.

 

Source rock = buried deep enough in the geological past to generate gas and oil. The deep part the basin where the gas and oil forms is called the kitchen or oven.

 

There are 600 sedimentary rock basins in the world, among them 40% are very productive, while the rest are barren. The unproductive basins either have no source rocks, the source rocks have never been buried deep enough to generate gas ad oil, or the basin has was overheated, and the oil was destroyed.

 

Minerals = crystals and grains in rocks.

 


amorphous   [/&/ 'morf/&/ s]    無定形的;結晶質的

 

Amorphous = minerals that have no crystal form

igneous rock  
火成岩

Granite is the most common intrusive, igneous rock. It has the coarse grained texture characteristic of all plutonic rocks. It consists of the minerals quartz, feldspar, biotite and hornblende.


Basalt = the most abundant volcanic rock. It has the fine-grained texture characteristic of lava.  Gas bubbles were frozen in the basalt.


gneiss   [nais]    片麻岩

Gneiss = product of intense metamorphism. It is easily identified by its foliated texture.


conglomerate   [k/&/ n'gl/o/ m/&/ rit]    密集而固結的

Conglomerate = a clastic rock with a wide range of pebble- to clay-size grains.


Sandstone = composed primarily of sand grains that have been naturally cemented together.

 

Shale = composed of clay-sized particles and is the most common sedimentary rock. It is usually well-layered and relatively soft. Shell breaks down to mud when exposed to water. Shale is commonly deposited on river floodplains and on the bottom of oceans, lake or lagoons.

 

Black Shale = common source rocks for gas and oil.

 

Gray Shale = a caprock on a reservoir rock in a petroleum trap.

 

Mudstone = similar to shale but is composed of both silt- and clay-sized grains.

 

Limestone = composed of calcite mineral grains that range in size from very fine to large, sparking crystals.

 

Many animals that live in the sea such as corals and clams secrete shells of lime (CaCO3).

 

Fossil Assemblage = a group of fossils found in the same sedimentary rocks.

 

Paleontologists = scientists who study fossils.

 

Weathering = the breakdown of solid rock.

 

Erosional Process = those that transport and deposit sediments.

 

Unconformity = Buried, ancient erosional surfaces are called unconformities.

 

Disformity = an erosional channel in which the sedimentary rock layers above and below the erosional surface parallel. It is an ancient river channel that is usually filled with sand that has become sandstone.

 

Angular unconformity = an ancient erosional surface in which the sedimentary rock layers below the unconformity are tilted at an angle to the layers above the unconformity. Angular unconformity can form gas and oil traps. The sedimentary rock layer above it must be a caprock that acts as a seal; usually a shale or salt layer; the gas and oil forms below the unconformity in a source rock as black shale. Angular unconformities can cover large subsurface areas, they can form giant gas and oil fields. (East Texas field discovered in 1930 by random drilling 72km by 8km with more than 30,000 wells with 5 billion bbls and the Prudhoe Bay field in Alaska are both angular unconformity traps.

 

Young Anticline = prolific petroleum producers occur as a line of hills that cross the LA basin. If the anticlines are relatively young, they havent been eroded and appear as topographic ridges on the surface.

Plunging anticlines/synclines = most anticlines and synclines are not level and are tilted with respect to the surface of the earth.


plunge   [pl/A/ nd/zh/ ]    鑽進;使陷入;投入;全埋在地 
義詞: dive; drop; fall; plummet


 

Nose = the pattern of an eroded plunging anticline or syncline is lobate-shaped, called a nose.


lobate   ['l/O/ beit]    lobe


 

Dome = a circular or elliptical uplift. When eroded flat, a dome forms a bulls eye pattern of concentric rock layers with the oldest rock in the center.

 

Middle East oil fields = anticline and dome traps.

 

Cushing oil field southwest of Tulsa = an anticline with three domes superimposed on it, which reservoir rock is the Bartlesville Sandstone along with several other sandstones and a limestone. It was the largest oil field during WWI.

 

Homoclines = sedimentary rocks dipping uniformly in one direction are known as a homocline. Alternating layers of hard and soft sedimentary rocks in a homocline will be eroded to form a series of parallel ridges on the surface of the ground.

 

Joints = fractures in the rocks without any movement of one side relative to the other. Joints in sedimentary rocks improve the reservoir qualities of the rock.

 

Faults = breaks in the rocks along which one side has moved relative to the other. The relative movement of each side is used to classify faults: dip-slip faults move primarily up and down; whereas strike-slip faults move primarily horizontal; oblique-slip faults have roughly equal dip-slip and strike-slip displacements.

 

Footwall = the side of a fault that extends under the fault plane

 

Hanging Wall = the side that protrudes above the fault plane

 

Throw = the vertical displacement on a dip-slip fault.

 

Downthrown Side = the side of the dip-slip fault that goes down

 

Upthrown Side = the side that goes up

 

Normal dip-slip fault = if the hanging wall has moved down relative to the footwall.

 

Graben is the down-dropped block between two normal faults.


horst   n.

Horst = the ridge left standing between two grabens.


 

Reverse dip-slip fault = if the hanging wall has moved up relative to the footwall. It is possible to drill through this fault and encounter the same rock layers twice in a double section. Reverse fault is caused by compression; while a normal fault is caused by tension (the opposite).

 

Sealing Fault = it prevents fluid flow across or along the fault.

 

Fault Traps = common but are usually relatively small because a single fault is linear and doesn’t have sides to contain large volumes of petroleum.

 

Two most common petroleum reservoir rocks are sandstones and carbonates (limestones and dolomites). Most sandstones and limestones however, are not reservoir rocks. Some reservoir rocks, such as limestone reefs and river channel sandstones, were deposited completely encased in shale. Because the shale below is a source rock for gas and oil and the shale above is a caprock, the reef or channel contains gas and oil. This is called a primary stratigraphic trap.

 


limestone   ['laimst/O/ n]    石灰石


dolomite   ['d/ol/ /&/ mait]    白雲石;白雲石山脈


encase   [in'keis]    進容器內;;圍繞


Sand Dunes are formed by wind in both desert and coastal environment. The only size is only clay-size and silt-size and is always well-sorted and can be excellent reservoir rock.

 

Rocky Mountain Overthrust Belt oil and gas fields = ancient dune sandstones formed extensive subsurface sandstone reservoirs (Jurassic age Nugget Sandstone).

 

Point Bars = the crescent-shaped well-sorted sand bars deposited on the inside of the river meanders

 

Incised Valley Fills = most river channel sandstones are deposited and preserved during a fall and rise of sea level. During sea level fall, the river incises (erodes) a valley; and during sea level rise, the valley is filled with sands. If the sands are overlain by a caprock, it can form a gas or oil trap.

 

Reefs = mounds of shells formed by a plant or animal. If the ancient reef is covered with a shale or salt caprock, it forms a gas and oil trap.

 

A large portion of the oil production in Canada comes from buried Devonian age atolls and carrier reefs, located primarily in Alberta.


atoll   ['/a/ tol]    環礁


Limestone Platform = a large area covered with shallow tropical seas where limestones are being deposited.

 

Oolites = As water saturated with calcium carbonate flows over the limestone platform, calcium carbonate precipitates out of the water forming sand- and silt-size spheres called oolites.


oolite   n. []魚卵石, 魚卵狀石灰石,鮞粒岩


 

Oolitic limestones = limestones composed of oolites. They have excellent original porosity and can be good reservoir rock.

 

Karst Limestone = A highly dissolved (by water with carbon dioxide = carbonic acid) limestone and can have excellent porosity and permeability. Some karst limestones have caves but more often they have solution pores up to several inches in diameter called vugs. The great Middle East oil fields are primarily in limestone reservoir rocks. Their excellent porosity and permeability come from vugs in the karst limestone.


karst   [ka:st]    石灰岩地區常見的地形


Chalks = extremely fine-grained limestones composed of microfossil shells (single-celled animals).

 

Dolomites = (CaMg(CO3)2) sedimentary rock that forms only by the alteration of a pre-existing limestone. Dolomite is often a good reservoir rock. Limestones tend to lose porosity when they are buried deeper due to compaction. Dolomites, however, are harder and less soluble than limestones and retain porosity. The dolomitized oil field reefs of western Canada have an average of 1% more porosity and 10 times greater permeability than the limestone reefs.

 

Sweden = no petroleum.

 

Middle East = more than one-third. Where the sedimentary rocks are thick, a large amount of petroleum is likely to occur. Where there are no sedimentary rocks, there is no petroleum.

 

Basin = a large area with thick sedimentary rocks. A basin is formed by subsidence of the basement rock. The depression is originally filled with ocean water and, eventually, with sediments. Subsidence occurred during the Paleozoic time and very thick carbonates and evaporates accumulated during the Silurian time at the Michigan basin.

 

Half-graben basins = formed by subsidence along one side of a normal fault.

 

Coastal Plains = formed by thick sediments deposited adjacent to an ocean. They originate when mountains are uplifted adjacent to a coast. As erosion lowers the mountains, streams deposit sands along the beaches, and waves carry the silts and clays offshore. The sandy beaches are deposited (prograde) out into the ocean, forming the coastal plain.

 

Gulf of Mexico Coastal Plain = 12km to 18km of sedimentary rocks. It is the of the most prolific petroleum producing areas of the world.

 

Atlantic Coastal Plain = barren for gas and oil, possibly due to the lack of source rock;


facies   n. 麵容, 外觀, 表麵, 外表, (生態學中的)演替係列優種社會, 演替係列變群叢, []


A single layer of sedimentary rock can be composed of several different rock types, each is a facies, a distinctive portion of the rock layer.

 

A Facies Change = change between rock types.

 

Sediments being deposited along the margin of an ocean have both a sandstone and shale facies.

 

As waves wash ashore, silt and clay are suspended in the water. The mud is carried offshore and deposited in deep water to become shale. Sand, too heavy to be suspended in the water by the waves, is deposited on the beach to become sandstone. This forms a layer of sediments with a shale (deep-water) and sandstone (beach) facies.

 

Jurassic Age Smackover Limestone = subsurface of the northern GOM coastal plain (4.6km to 6km) and in some area it is good reservoir rock. The best reservoir rock is the oolite facies. In Texas, parts of the oolite facies have been dolomitized, increasing the porosity to 30%. The salt facies, in contrast, is impermeable and acts as a caprock.

 

Sandstone pinch or wedge out in a shale layer = trap

 

Pinch out of dolomite in salt along the edge of a basin = trap

 

Sometimes the boundary between two facies is harp, and the rock interfinger or wedge out in another rock layer.

 

Topographic map = shows the elevation of the earth’s surface.

 

Geological Map = shows where each rock layer crops out on the surface of the earth. Each rock layer is given a different pattern, color, and symbol on the map.

 

A formation = the basic sedimentary rock layer used for geologic mapping. A formation is a mapable rock layer with a definite top and bottom. Geologists have divided all sedimentary rocks into formations.

 

A formation = has a two-part name. The first part is a town, where the layer crops out on the surface; the second part is the dominant rock type, such as sandstone or limestone. E.g. Bartlesville Sandstone.

 

If the sedimentary rock layer is a mixture of rock types, the word formation is used: The Coffeyville Formation (composed of both sandstone and shale).

 

Members = Formations ca be subdivided into smaller units. A member is a distinctive but local bed in a formation. It is also given a formal, two-part name. For example, the Layton Sandstone Member is part of the Cofferyville Formation.

 

If the member is only found in subsurface, it is given a letter and number such as the H5 Sands Member. Adjacent formations of similar rocks can be jointed to form a group and given a geographic name (i.e. the Chase Group).

 

A geologic map is a flat, two-dimensional representation of the earth’s surface.

 

Strike = horizontal orientation of a plane, such as a sedimentary rock layer or a fault.

 

Dip = the direction and vertical angle of the plane, it is measured perpendicular to the strike line.

 

A Base Map = a map that shows the position of  the wells that have drilled in an area.

 

Spotting a well = involves that location of a wellsite and placing the well symbol on a base map.

 

A Structure Map = uses contours to show the elevation of the top of a subsurface sedimentary rock layer. An important structural map would be one contoured on the top of a potential reservoir rock or drilling target. Faults are shown as a straight line.

 

An Isopach Map = uses contours to show the thickness of a surface layer. If an oil or gas field has been drilled, an Isopach map can be made of the pay zone.

 

Pay Zone = the vertical distance in a well that produces gas and/or oil.

 

Gross Pay = contours the entire reservoir thickness including nonproductive water-bearing and tight zones.

Net Pay = contours only the productive thickness of the reservoir. A net pay isopach map of a reservoir is used to calculate the reservoir volume and the oil and gas reservoir.

 

Sandstone Pinch or Wedge Out = the isopach contour becomes zero.

 

A Percentage Map = plots the percentage of a specific rock type such as sandstone in a formation. Higher percentages of reservoir quality rocks, such as sandstones and carbonates, imply a larger reservoir net pay.

 

The continents are surrounded by a shallow, almost flat platform, the Continental Shelf. It extends from the beach out with a slope of less than 1 degree to the shelf break.

 

The Shelf Break is located in an average water depth of 140m. The width of the continental shelf varies from 0.8km to 800km with an average with of 80km.

 

Continental Slope = seaward of the continental shelf and slope break. The continental slope leading down to the bottom of the ocean has a slop of about 4 degrees and is the geological edge of the continents.

 

Trubidity current deposits are called turbidites and can be sandstone reservoirs.

 

turbidity   [t/&r/ 'bid/&/ ti]    混濁;混亂

 

Deep-water production on the continental slopes of the GOM, western African, and Brazil are from turbidite sands deposited in submarine canyons and submarine fan distributary channels now buried in the surface. The sands are relatively young and have not been buried too deep. Because of that they often have porosites of 20 to 30%, thousands of millidarcy permeability, and are excellent reservoir rocks. They riled oil and gas a high rate to wells to justify the cost of drilling in deep water.

 

The deepest parts of the seafloor are Ocean Trenches.

 

The basement rock that forms the crust of the earth is basalt lava rock. It averages 8km in thickness. Continents are high in elevation because they also have granite, averaging 27km. Much thicker than basalt.

 

A Source Rock is a rock that forms gas or oil. The source of gas and oil is organic matter preserved in sedimentary rocks. Some organic matter is preserved when quickly buried by other sediments before it decayed or was deposited on the bottom of a sea with stagnant, oxygen-free waters. The black color of sedimentary rocks include coal, shale and some limestones.

 

Plant material is transformed into coal by temperature and time. Wood and coal have a specific chemistry that can generate only methane (CH4) gas. That’s why coalmines are dangerous. Wells are often drilled to Coal Bed to produce Coal Bed or Coal Seam Gas (methane gas).

 

The gas occurs adsorbed to the surface of the coal along natural fractures called Clints. A coal seam gas well first produces water for a period of time up to a year as the fractures drain. As the pressure in the coal decreases, the methane gas is released from the surface of the coal. (including non-woody plant, algae).

 

Black Shale = commonly 1 to 3% organic matter by weight; it can have up to 20%.

 

Green Shale or Gray Shale = 0.5%

 

Middle East, Dark Limestones are also source rocks.

 

Biogenic or Microbial gas = large volumes of methane gas (swamp or marsh gas) generated by bacterial action on the organic matter at relative4 shallow depths. Generation of biogenic gas decreases with depth as bacterial action decreases with increasing temperature.

 

biogenic adj. 源於生物的, 生物所造成的

 

microbial [mai'kr/O/ bi/&/ l]  微生物.細菌引起的

 

microbe ['maikr/O/ b]  微生物;細菌

 

marsh [ma:/ch/ ]  沼澤;沼地;濕地

 

Immature Oil = Heavy oil 150 F-200 F

 

Mature Oil = light oil  250 – 300 F

 

> 300F crude oil is irreversibly transformed into graphite and natural gas. This temperature can only happens at a depth of about 5.5km in a sedimentary rock basin.

 

The generation of a liquid or gas from a solid causes a large increase in volume. This stresses the source rock and fractures the shale.

 

Carrier Beds = rock layers that are very permeable and transmit fluids.

 

Migration = the vertical and lateral flow of the petroleum from the source rock

 

Only about 0.3 to 36% of all the gas and oil that forms in a sedimentary rock basins, is ever trapped.

 

Light Oil and Thermogenic Gas can migration a long distance.

 

Free Gas Cap = Once the gas and oil migrate into the trap, the gas being lightest, goes to the top of the trap to form the free gas cap.

 

Oil Reservoir = the oil goes to the middle of the trap

 

Salt Water = the heaviest goes to the bottom.

 

A Saturated Pool = always has a free gas cap on top of the oil reservoir. The oil in the reservoir has dissolved all the natural gas it can hold and is saturated.

 

An Unsaturated Pool = lacks a free gas cap. The oil has some dissolved gas but it can hold more and is unsaturated.

 

Sometime there is only a gas reservoir on water.

 

Gas-oil Contact = the boundary in the reservoir between the free gas cap and the oil.

 

Oil-water Contact =

 

Crest = the top of the trap.

 

The exploratory well is usually drilled on structure (on the crest).

 

Off Structure = when a well is drilled to the side of the crest.

 

A Dry Hole, Duster or Wet Well = If a well is drilled too far off structure, it might not encounter commercial amounts of oil or gas

 

duster ['d/A/ st/&r/ ]  打掃灰塵的人;抹布;防塵外衣

 

Caprock or Seal = in a trap the reservoir rock must be overlain by caprock or seal, an impermeable rock layer that doesn’t allow fluids to flow through it.

 

Shales and Salt Layers = two common caprocks. Well-cemented or shaly rocks, micrite, chalk and permafrost can also be caprocks.

 

Oil in Oklahoma = generated and trapped during the Pennsylvanian time. (325 – 290 Million Years—Coal Deposites)

 

North Slope of Alaska = Cretaceous time (144-65 Million Years—Flowering plants, modern insect, bird and mammal groups)

 

Gulf of Mexico = some of the oils are very young, just a couple million years old, and some oil is probably still forming and accumulating today.

 

A Reservoir Rock = a rock that can both store and transmit fluids. A reservoir rock must have both porosity and permeability.

 

Porosity = is the percent volume of the rock that is not occupied by solids.

 

Pore = the spaces of a porous rock.

 

There are several accurate methods to measure porosity using well cuttings, cores, and wireline well logs.

 

Well Cutting or Rock Chips = made by the drill bit are flushed up the well by the drilling mud. Well cutting are exampled by geologists using binocular microscope to identify the rock types and see the pores.

 

A Core is a cylinder of rock that is drilled from the well. A small Plug in the shape of cylinder is cut from the core. The plug is then dried to remove the fluids from the pores. Porosimeter is used then to measure the porosity of the plug.

 

Three sideline well logs—Neutron Porosity, Formation Density and Sonic-Velocity logs.

 

Very deep gas reservoirs need very little porosity because of the very high pressure.

 

Porosity=0~5% is insignificant; 5~10% is poor; 10~15% fair; 15~20% good; 20~25% excellent.

 

Porosity Cutoff = a minimum porosity value is often used to help decide whether or not to complete an oil well. (Sand stone is 3~5% porosity cutoff).

 

Permeability = a measure of the ease with which a fluid can flow through a rock. Permeability is measured in Darcies (D) or milidarcies (md). A millidarcy is 0.001 Darcy.

 

A Darcy = the permeability that will allow a flow of a cubic centimeter under a differential pressure of a atmosphere.

 

Permeameter = used to measure the permeability of the dried plug by measuring the flow of air or nitrogen through it.

 

10md = poor; 10-100md = good; 100-1000md is excellent (for an oil reservoir)

 

Tight or Tight Sands = A very low or no permeability sandstone or carbonate.

 

Any fractured rock can be a reservoir rock. Fractured shales, cherts and chalks are reservoir rocks in many fields.

chert [t/ch/ /&r/ t]  黑矽石;角岩

 

serpentine ['s/&r/ p/&/ nt/E/ n]  蛇的;層層卷繞的

 

IN East of Austin, volcanoes erupted during the Cretaceous time; the area was covered with GOM waters. The submarine lava spread out along the ocean bottom, forming mushroom-shaped deposits of basalt. The surface of the basalt was highly fractured and weathered by seawater, giving it porosity and permeability. Sediments then covered the volcanoes that are not buried in the Texas coastal plain. Oil later migrated up into the weathered basalt that is called serpentine by the drillers.

 

Granite Wash = potential reservoir rock formed by the weathering of granite. Granite is composed of large, well-sorted, sand-sized mineral grains and weathers to form well-sorted sandstone that can be very thick. After the granite and granite wash have been buried in the subsurface, oil and gas can form in source rocks at a lower elevation. The oil and gas can then migrated up and into the granite wash.

 

Saturation = the relative amount of the oil/gas and water sharing the pores of the reservoir will vary from reservoir to reservoir and is called saturation. It is expressed as a percent and always adds up to 100%.

 

Oilfield Brine = very salty water that shared the pores with the oil. Saturation is why most oil wells pump not only oil, but also water called oilfield brine.

 

Oil Shales = sedimentary rocks rich in a type of organic matter called kerogen. Oil Shales are organic-rich source rocks that are old enough but have never been buried deep enough for heat to transform the organic matter into oil. They are immature source rocks.

 

kerogen n. [] 油母岩質, 油原

 

Shale Oil = when the oil shale is heated to about 350C, kerogen is transformed into crude oil called Shale Oil.

 

Because the oil shale crops out, it can be surface-mined. The oil shale on the sides of the cavern is set on fire for heat to generate oil in the subsurface.

 

Tar Sands = composed of very heavy oil mixed with sands. The oil is too viscous to be produced by conventional methods. Very large tar sand deposits occur in northern Alberta and Venezuela.

 

Spill Point = The trap can be filled down to a level, called the spill point, at which it cannot hold any more.

 

Field = the surface area directly above one or more producing reservoirs on the same trap such as an anticline. The field is commonly given a geographic name such as a town, hill or creek.

 

A Reservoir = a subsurface zone that produces oil and gas but does not communicate with other reservoirs.

 

Structural Traps = formed by deformation of the reservoir rock, such as a fold or fault – anticlines and domes

 

Primary stratigraphic traps = formed by deposition of the reservoir rock, such as a river channel sandstone or limestone reef that is often completely encased in shale.

 

A Secondary Stratigraphic Trap is formed by an angular unconformity.

 

A Combination Trap has both structural and stratigraphic elements.

 

Rollover Anticline = a large potential gas and oil trap, commonly occurs on the basin side of the growth fault.

 

Sealing Faults = divide the structure into individual procuring compartments or pools. They may have different oil-water and gas-oil contacts in reservoir level, or pressure level.

 

Drag Folds = formed by friction generated along a fault plane when a fault moves. Friction causes the beds on either side of the fault to be dragged up on one side and down on the other side of the fault.

 

Overthrust or Disturbed Belts = where most mountain ranges on land were formed by compressional forces and display compressional features such as folds, reverse faults and thrust faults. (Rocky Mountains, numerous thrust faults and the  drag folds in the Nugget Sandstone at 3km below the surface)

 

Secondary Stratigraphic Traps = Angular Unconformities angular unconformities can form giant gas and oil traps when a reservoir rock is terminated under an angular unconformity and overlain by a seal.  Example: East Texas field with 5 billion bbls and Prodhoe Bay field with 13 billion bbls (Permian-Triassic age Sadlerochit Sandstone).

 

Primary Stratigraphic Traps = Reefs, Beaches, River Channels and incised valley fills and updip pinch outs of sandstones form primary stratigraphic traps.

 

Salt = composed primarily of halite, is a solid that flows slowly as a viscous liquid under pressure. A salt layer is formed by the evaporation of water.

halite ['h/a/ lait]  岩鹽 (highly soluble)

 

Piercement Dome = When sands and shales are deposited on the salt layer, the weight of the overlying sediment presses down on the salt layer. The salt lifts up a weak area in the overlying sedimentary rocks,. As the salt rises, it uplifts and pierces overlying sedimentary rocks to form a piercement dome.

 

Large amounts of salt are dissolved as the rising salt dome comes in contact with water in the overlying sediments. However 1 to 5% of the salt is insoluble anhydrite. As the salt dissolves, an insoluble layer called the caprock builds up on the top of the dome. This caprock ranges from 30 to 300M thick.  The caprock if often highly fractured and has vugular pores.

 

anhydrite [/a/ n'haidrait]  硬石膏;無水石膏

 

Individual salt domes often have numerous petroleum traps. There can be hundreds of Salt Overhangs in all directions.

 

cavernous ['k/a/ v/&r/ n/&/ s]  洞穴的;凹的

 

dolomite ['d/ol/ /&/ mait]  白雲石;白雲石山脈

spindle ['spindl]  紗錠;紡錘;;線長度單位

spindle-legged adj. 有細長腿的

spindle-shanked adj. 有細長腿的

The Spindletop slat dome near Beaumont, TX was the first salt dome successfully drilled for petroleum (1901). A large mound with gas seeps marked the surface expression of the Spindletop salt dome. A well on that mound was drilled into the Spindletop caprock at just below 300m in 1901. The caprock was very cavernous dolomite with high-pressure oil in it. The well blew out as the world’s first great gusher at the rate of 100k bbls of green-black oil per day to a height of 30m above the derrick.

 

gusher ['g/A/ /ch/ /&r/ ]  迸出物;噴油井;容易動感情者

 

Within 9 months, 64 more wells were completed into the Spindletop caprock, each producing a gusher. Production was depleted in 1903 because of unrestricted production. It was not until 1925 that the deeper oil along the flanks of Spindletop was discovered. Spindletop created more than 100 companies, including Texco.

 

Petroleum Geologist = exploration and development of petroleum reservoirs

 

Exploration Geologist = searches for new gas and oil fields

 

Development Geologist = directs the drilling of wells to exploit a field

 

Petroleum Geochemist = uses chemistry to explore for and develop petroleum reservoirs.

 

A Marker Bed = a distinctive rock layer that is easy to identify. Volcanic ash layers, thin beds of coal, limestone, or sandstone, and fossil zones are good marker beds.

 

A Key Horizon = the top or bottom of a thick, distinctive rock layer, can also be used to start the correction.

 

A Stratigraphic Cross Section is made by hanging the well logs from the same market bed in each well.

 

Scouts = Large oil companies use scouts who gather information on any petroleum-related activity in their assigned region. A scout uses all kinds of ethical methods to find out where competitors are exploring, leasing and drilling. The scout fills out a form, called a scout ticket.

 

Scouts from different oil companies meet periodically to coordinate their efforts and exchange information in scout checks or meetings.

 

Well-cutting Libraries = collect well cutting for a regional area.

 

Well-core Libraries = collect cores drilled in that state, province, or country.

 

A Play = a combination of trap, reservoir rock, and seal that has been shown by previously discovered fields to contain commercial petroleum deposits in an area.

 

A Tread or Fairway is the area along which the play has been proven, and more fields could be found.

 

fairway ['f/ar/ wei]  航路;水路;修整過的草地

 

A Prospect = the exact location where the geological and economic conditions are favorable for drilling and exploratory well.

 

Gravity Meter = very sensitive to the density of the rocks in the subsurface. It measures gravity in units of acceleration called milligals. A mass of relatively light rocks such as a slat doom or porous reef can be detected by the gravity meter because of lower than normal gravity values over it.

 

Salt has lower reading in magnetics because the salt is light in density and has no magnetite mineral grains compared to the surrounding sedimentary rocks

 

A dome or anticline can be identified by both a high gravity and high magnetic anomaly. This is caused by dense and magnetite-bearing basement rock that is closer to the surface int eh center of the structure.

 

Fee Land = In the US and parts of Canada, private land is called fee land and has two, separate ownerships, a surface rights and a mineral rights owner.

 

Surface Rights Owner = can build a house, ranch or farm on the land

 

Mineral Rights Owner = explore and drill for gas and oil and owns and can produce the gas and oil.

 

About one-third of the mineral rights on land in the US is owned by the federal or state government in public land.

 

Landman = to identify and locate the mineral rights owner of free land.

 

Authority or Authorization for Expenditure (AFE) = is completed. This form estimates the cost o drilling and completing the well, both as a dry hole and a producer. Costs such as drilling intangibles, completion intangibles, and equipment are listed.

 

Intangibles = salaries, services, and e2quipment that cannot be salvaged after the well is drilled.

 

A Wildcat or Controlled Exploratory Well = a well drilled to discover new oil or gas reserves.

 

Discovery Well = if the well does discover a new field, it is called the discovery well for that field.

 

Developmental Wells = wells drilled in the known extent of the field

 

Infill Wells = wells drilled between producing wells in an established field to increase the production rate

 

Cable Tool Rig is relatively simple, had been in use for hundreds of years. An engine, originally a steam engine, and causes a wooden walking beam to pivot up and down on the Sampson Post. Cable Tool Rig is very slow (7.5m a day).

 

Rotary Drilling Rig = replaced the cable tool drilling rig in 1895 to 1930. Must faster (several hundreds or several thousand feet per day.)

 

Rotary Drilling Rig rotates a long length of steel pipe with a bit on the end of it to cut the hole called the wellbore. The rotary rig consists of four major systems=>power, hoisting, rotating and circulating systems.

 

Power = diesel engines. => Most power goes to the hoisting and circulating systems. Some new and on most marine rigs, a silicon-controlled rectifier is used in a diesel-electrical system.

 

Hoisting System = the Derrick or Mast

 

mast [m/a/ st]  ;主人;首領;名作;公子;碩士

動 支配;熟練;裝桅竿

mast- (=masto-)表示“乳頭, 乳房”之義(用於元音之前)

Drillstring = the turning drillpipe, bit and related equipment is called the drillstring.

Swivel = allows the drillstring  below it to rotate on bearings in the swivel while the weight of the pipe is suspended from the derrick.

 

Kelly = below the swivel is located a very strong 4- or 6-sided, high-grade molybdenum steel pipe called the Kelly. The Kelly has sides to enable it to be gripped and turned by the rotary table. The Kelly turns all the pipe below it to drill the hole.

 

swivel ['swivl]  旋轉;回旋

swivel-eye n. 斜視眼

swivel-eyed adj. 斜視的

Rotary Table = a circular table in the derrick floor that is turned clockwise by the prime movers. If it were turned in the opposite direction, the drillpipe would unscrew.

 

Drillpipe = the round, heat-treated alloy steel drillpipe ranges from 5.5~14m long but is commonly 10m long. The pipe is threaded with male connections on each end. There is a female connection.

 

Circulating System = mod tank, mud agitator and a mud gun.

 

Geothermal gradient = 3.6C/100M. In OK, surface temperature = 13 C (averaged), oil in a 3km reservoir is 90 C, so it is very hot.

 

There are two separate pressures in the subsurface. The pressure on the rock is called earth or lithostatic pressure.  The pressure on the fluids in the pores of the rock is reservoir, formation or fluid pressure.

 

During drilling, the pressure of the drilling mud is usually slightly higher (overbalance) than hydrostatic pressure to keep the fluids back in the rocks.

 

Fishing = a common drilling problem is that something breaks in or falls down the well during drilling. Fishing tools are leased from a service company to grapple for the fish in a process called fishing.

 

grapple ['gr/a/ pl]  抓住;握住;捉捕;把握;鉤住

 

A Blowout = abnormal high pressure, an uncontrolled flow of fluids up the well. Natural gas flowing out the well can catch fire, causing the loss of the drilling rig.

 

A Kick = fluids flow out to the subsurface rocks into the well in what is called a kick.

 

Pit-volume totalizer uses floats in the mud tanks to continuously monitor and record drilling mud volume. It sounds an alarm if the mud volume decreases due to lost circulation or increases due to a kick.

 

Kill Mud = heavier drilling mud is pumped into the well through the choke manifold.

 

Directional or Deviation Drilling

 

1 ft = 0.3048 m

1 m = 3.2808 ft

1 mile = 1.609 km

1 gallon = 3.7854 L
