allowable annular surface pressure.

n: the amount of oil or gas that can be produced legally from a well. In a state using proration, this figure is established monthly by its conservation agency. See proration.

the production limit set on a specific well by a government regulatory body. Rarely seen.

the maximum stress allowed by code or other agreement or study as a fraction of test pressure. Design pressure of the system is related to hoop stress.

n: in an oil and gas lease, a clause designed to keep drilling operations going steadily after the primary term has expired. In some clauses, designated intervals between completion of one well and commencement of the drilling of another may require the operator to develop the leased land up to its allowable density.

n: The allowable maximal well spacing that can prove the highest oil recovery factor.

n: A wellbore that has deviated from the vertical. Crooked holes usually occur where there is a section of alternating hard and soft strata steeply inclined from the horizontal.

a wellbore drilled in excess of the maximum allowable dogleg.

v: to remove water from a substance. Dehydration of crude oil is normally accomplished by treating with emulsion breakers. The water vapor in natural gas must be removed to meet pipeline requirements;a typical maximum allowable water vapor content is 7 pounds per million cubic feet (3.2 kilograms per million cubic metres) per day.

n: (HAP)(CAA) air emissions that are immediately hazardous to human health or that cause cancer, gene mutation, or reproductive harm. Due to its harmful nature, the allowable emission of a hazardous airborne pollutant is much lower than that for a conventional, or criteria, pollutant.

the allowable effective fluid density difference between the fracturing pressure and the pressures exerted b a fluid that are needed to control formation flow and the wellbore.

n: the amount of pressure that the casing seat can take without fracturing. It is calculated from the height and volume of the kick in the well.

n: after overflow and shut in, the maximum difference the fluid density in the hole from the equivalent density that converted by casing allowable pressure and volume pressure in the holebore unless it happens overflow.
