adj. said of any pressure-tight vessel or container when the internal pressure is lower than atmospheric pressure.

n: see check valve.

n: a kinds of highest positive valence compound.

opening pressure of a gas lift valve at depth.

abbr: Organization of Petroleum Exporting Countries.

Organization of Petroleum Exporting Countries. (1983 list: Saudi Arabia, Kuwait, Iran, Iraq, Venezuela, Quatar, Libya, Indonesia, United Arab Republic, Algeria, Nigeria, Ecuador and Gabon.).

n: motor enclosure that allows ample outside air to move through the motor to cool it while affording protection against mild weather conditions. The angle of protection is 15 from the vertical.

n: the theoretical maximum capacity of a gas well as determined by a test conducted under limiting conditions. The method of determining this potential varies from state to state.

the maximum potential rate from the well if all back pressure was removed.

n: a test made to determine the volume of gas that will flow from a well during a given time span when all surface control valves are wide open.

n: under the condition that all controll valve openes fully , the gas production test is ascertained at certain interval time.

n: a relatively small calibrated tank, open to the atmosphere. Often used to prove meters at loading racks. In use, the meter to be proved is set at zero and the prover tank is filled to a calibrated height while the meter registers the amount of liquid flowing d1rough it. When the tank is filled, the calibrated volume in it is compared to the volume the meter registered. If the meter is inaccurate, it is adjusted or a factor is used to compensate for the inaccuracy.
