n: the pressure base that state regulations require for the reporting of gas volumes. The pressure base for reporting to the states of Texas, Oklahoma, and Kansas is 14.65 pounds. Louisiana and California pressure bases are 15.025 pounds and 14.73 pounds, respectively.

n: a volume of gas determined in accordance with measurement standards prescribed by state regulations.

n: the extent of variation between the lowest and highest static pressures that a particular orifice meter can record.

n: A kind of experimental well control way.

n: on offshore drilling rigs and production platforms, a poster that gives duties and places for each individual on the rig or platform for various types of emergeocies. Every person on the rig or platform should be familiar with the station bill.

n: 1. a with vane-like blades d1at serves to direct a flow of fluid (such as drilling mud) onto another set of blades (called the rotor). The stator does not move;rather, it serves merely to guide the flow of fluid at a suitable angle to the rotor blades. 2. the stationary part of an induction-type alternating- current electric motor. Compare rotor.

n: A kind of axial flow vane wheel,which is non-tatating when system work ,its leaf blades distort according to a definite direction,its bladings have the function of diversion and energy transformation

n: a closed steel vessel or container in which water is heated to produce steam.

n: a pipe, or set of pipes, within an emulsion settling tank through which steam is passed to warm the emulsion and make the oil less viscous. See fire tube.

n: a method of improved recovery in which steam is injected into a reservoir through injection wells and driven toward production wells. The steam reduces the viscosity of crude oil, causing it to flow more freely. The heat vaporises lighter hydrocarbons;as they move ahead of the steam, they cool and condense into liquids that dissolve and displace crude oil. The steam provides additional gas drive. This method is used to recover viscous oils. Also called continuous steam injection or steam flooding. Compare cyclic steam injection, thermal recovery.
