valence state +3 iron in solution. A very common catalyst in oil field emulsion and sludge formation. Precipitates at iron hydroxide when the pH exceeds 1.8 to 2.2 (depending on sour conditions).

n: cord or rope of vegetable or synthetic fibre used as the axial member of a rope.

n: 1. a geographical area in which a number of oil or gas wells produce from a continuous reservoir. A field may refer to surface area only or to underground productive formations as well. A single field may have several separate reservoirs at varying depths. 2. the magnetic field in a motor or generator, or that part of a motor or generator that produces a magnetic field;the magnetic field about any current-carrying electrical conductor.

n: A geological area in which oil or gas wells are producing from a continuous reservoir.

one or more reservoirs grouped by or related to the same general geologic structural feature or stratagraphic condition.

n: a value used to quickly determine gas volume flow: it is derived from several factor, such as the basic orifice factor (Fb),and the pressure base factor (Fph)

n: a wire rope strand in which two layers of wire of the same size are laid around a centre wire, with the inner layer having half the number of wires of the outer layer. Small wires-the filler wires - are laid in the valleys of the inner layer.

the material used to make up a filter bed. Common filter media are DE, sand, various fibers, etc.

n: the area of valid filter medium in filter press when take an experiment about fluid loss

n: the viscosity of the liquid phase in fluid
