n: the US Department of the Interior, Minerals Management Service rules and regulations that must be followed by those who drill and produce oil and gas wells located in the Outer Continental Shelf.

n: The operation of a round pulling out the hole and running due to bit change or other reasons.

annualized average incremental oil rate.

v: to cease producing oil and gas from a well when it becomes unprofitable or to cease further work on a newly drilled well when it proves not to contain profitable quantities of oil or gas. Several steps are involved: part of the casing may be removed and salvaged;one or more cement plugs are placed in the borehole to prevent migration of fluids between the different formations penetrated by the borehole;and the well is abandoned. In most oil-producing states, it is necessary to secure permission from official agencies before a well may be abandoned.

to cease efforts to produce or inject fluids in a wells and to plug the well sufficiently to protect the environment and the ability to redrill and develop other reserves at a later date.

v: To stop drilling or production operations when it becomes unprofitable. A wildcat may be abandoned after poor results from a well test. Cement plugs are placed in the wellbore to prevent fluid migration between different zones.

n: a well not in use because it was a dry hole originally, or because it has ceased to produce. Statutes and regulations in many states require the plugging of abandoned wells to prevent the seepage of oil, gas, or water from one stratum of underlying rock to another.

n: Usually refers to a well which has no valuable oil or gas production or a dry hole. In general, it should be packed by cement plug.

n: termination of a jurisdictional sale or service. Under Section 7(b) of the Natural Gas Act, the Federal Energy Regulatory Commission must determine in advance that the present or future public convenience and necessity" or depletion of gas supplies requires termination.

n: the average reservoir pressure at which an amount of gas insufficient to permit continued economic operation of a producing gas well is expelled. abd, abdn abbr: abandoned;used in drilling reports.

The minimum pressure of the reservoir when the wells are abandoned.

a theory of petroleum generation in which petroleum is thought to have formed from hydrocarbons trapped inside the earth’s crust when the earth was forming. See also Biogenic and Organic theories.
