Water control

Oil & gas; Oilfield

A treatment conducted within a reservoir or perforated interval to reduce water production. Water-control treatments may be necessary when the production efficiency of a well, or the process ...

Pitting

Oil & gas; Oilfield

A type of corrosion in which there is loss of metal in localised areas. The corrosion rate in the pits is many times greater than the corrosion rate on the entire surface. The resultant pits can be ...

Corrosion fatigue

Oil & gas; Oilfield

A type of corrosion in which the metal components of a structure fail due to cyclic stresses applied in a corrosive environment, such as salt water. Consequently, a break in the metal will occur at ...

Poppet valve

Oil & gas; Oilfield

A type of cheque valve often used in the lines or manifolds associated with kill and choke lines or pressure-control equipment.

Back-pressure valve

Oil & gas; Oilfield

A type of cheque valve, typically installed in the tubing hanger, to isolate the production tubing. The back-pressure valve is designed to hold pressure from below yet enable fluids to be pumped from ...

Progressive cavity pumping system

Oil & gas; Oilfield

A type of a sucker rod-pumping unit that uses a rotor and a stator. The rotation of the rods by means of an electric motor at surface causes the fluid contained in a cavity to flow upward. It is also ...
