---------- C ---------- Caprock is a hard impervious formation that forms a cap over permeable layers of sedimentary rock. This prevents the further upward migration of oil and gas and traps the hydrocarbon. Carbon black is also known as Channel black, Lamp black, Furnace black, Thermal black or Acetylene black. It is an odorless solid; mainly used in automobile tire manufacture and road construction. Carbonate rocks are "Chemical or Biochemical" in origin; they form within the basin of deposition, and are called Intrabasinal Rocks; composes of calcite and argonite; has high porosity and permeability and where scientist usually find oil and gas. Carried Interest is interest created from an oil and gas lease that is free of some or all of the costs. Casing is installed during the drilling process to: protect potable water zones near the surface from contamination, provide a smooth conduit for moving tools into and out of the hole, isolate down hole zones so they can be produced separately and protect the hole from the drilling fluids. Chemical formula Gives the number and type of atoms making up a a chemical compound. It indicates the number of atoms of each element that are part of the compound. Circulation process is the round trip made by the drilling mud; down through the drillpipe and back up the annulus between the pipe and the wall of the borehole. If circulation is lost, the flow out f the well is less than the flow into the well; the mud may be escaping into some porous formation or a cavity downhole. The circulating system pumps drilling fluids down the hole, out of the nozzles in the drilling bit, and returns them to the surface where the debris is separated from the fluid. Compressed natural gas (CNG) is natural gas that is under pressure. The pressure reduces the volume occupied for the gas so it can be contained in a smaller vessel. Conveyance is a transfer of ownership of a property from one party to another. Crude oil is the petroleum liquids as they come from the ground; formed from animal and vegetable material which collected at the bottom of ancient seas. Cryogenic recovery processes are done at temperatures lower than -150 °F. The low temperatures allow the plant to recover over 90% of the ethane in the natural gas. Most new gas processing plants use cryogenic recovery technology. Custody relates to when the ownership of oil changes. A run ticket is prepared for the receiver and the shipper to record the transaction. Cuttings are chips and small fragments of rocks as the result of drilling that are brought to the surface by the flow of drilling mud as it is circulated. Cuttings are important to geologist, who examines them for information concerning the type of rock being drilled.
