The proper plugging and abandoning of a well in compliance with all applicable regulations, and the cleaning up of the wellsite to the satisfaction of any governmental body having jurisdiction with respect thereto and to the reasonable satisfaction of the operator.(2) To cease efforts to find or produce from a well or field.(3) To plug a well completion and salvage material and equipment.
The costs associated with abandoning a well or production facility. Such costs are specified in the authority for expenditure (AFE), and typically cover the plugging of wells; removal of well equipment, production tanks and associated installations; and surface remediation.
The gas accumulated on the surface of a solid material, such as a grain of a reservoir rock, or more particularly the organic particles in a shale reservoir. Measurement of adsorbed gas and interstitial gas, which is the gas contained in pore spaces, allows calculation of gas in place in a reservoir.
– A down hole tool used in conjunction with a jar to store energy that is suddenly released when the jar is activated. The energy provides an impact force that operates associated down hole tools or, in a contingency role, helps release a tool string that has become stuck. Depending on the operating mode, the energy in tension or compression can be stored by means of a mechanical spring or a compressible fluid such as nitrogen gas. Accelerators should be selected on the basis of their compatibility with the jar to be used.
(1) The act or process of reducing the intensity of pollution.(2) The use of some method of abating pollution.
American Petroleum Institute (API)
The American Petroleum Institute is the primary trade association representing the oil and natural gas industry in the United States.
The space between: (1) The casing and the wall of the borehole.(2) Two strings of casing.(3) Tubing and casing.

Code An indicator developed by the American Petroleum Institute (API) to identify areas such as counties and other subdivision areas identified within state boundaries. Defined by API Bulletin D12A, as amended. This code becomes a part of the API Well Number.
Api State Code
The indicator assigned to a state, as defined in API Bulletin D12A, as amended. This code is a part of the API Well Number (The Api State Code for Colorado is 05).
Api Well Number
A well identifier assigned as defined in API (American Petroleum Institute) Bulletin D12A, as amended. The API Well Numbers are assigned by the appropriate state or federal regulatory agency.
A well drilled as part of an appraisal drilling program which is carried out to determine the physical extent, reserves and likely production rate of a field.
A chemical enhanced oil recovery flood that uses two sources of surfactant and a polymer. Alkaline chemicals such as sodium carbonate react with acidic oil components in situ to create petroleum soap, which is one of the surfactants. A synthetic surfactant is injected simultaneously with the alkali. A water-soluble polymer is also injected, both in mixture with the alkali and surfactant and as a slug following the mixture, to increase the viscosity of the injectant, thereby improving mobility control of the flood fronts.
