the inside annulus;tubing-by-production casing annulus. (Note, there may be regional differences in the A, B, C annulus designations and some are reversed. Inside annuli (IA) and outside annuli (OA) are more universally descriptive.)

n: 1. a derrick or crane shaped like the letter A and used to handle heavy loads. 2. an A-shaped openwork structure that is the stationary and supporting component of the mast of a jackknife rig and to which the mast is anchored when it is in an upright or drilling position. 3. the uppermost section of a standard derrick, shaped like the letter A and used as a support in lifting objects such as the crown block to the water table.

n: A kind of "A" frame gin pole, used to elevate heavy object.

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: 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 failure mode that can cause the cancellation-of or immediate-halt-to a project or event. Generally expressed as a percent probability.

n: It is connected above the packer of DST tool, which is used to protect the tubular subs which are installed with bourdon tube.

n: the amount of moisture present in the air. It may be expressed in milligrams of water per cubic metre of air. Compare relative humidity.

n: the value obtained when the absolute dynamic viscosity is divided by the density (expressed in grams per cubic centimetre) of the liquid at the temperature concerned.

n: the percentage of the total bulk volume of a rock sample that is composed of pore spaces or voids. See porosity.

the percentage of the total bulk volume that is pore spaces, voids or fractures.

n: total pressure measured from an absolute vacuum. It equals the sum of the gauge pressure and the atmospheric pressure. Expressed in pounds per square inch.

the reading of gauge pressure plus the atmospheric pressure.
