n: see alkaline (caustic) flooding, micellarpolymer flQoding.

one of several methods involving injecting a chemical into a formation to improve the production of hydrocarbon. May be from an injection well to a production well or injection into a producer with a soak period before recovery.

n: the injection of steam into the rock surrounding a production well to lower the viscosity of heavy oil and increase its flow into the wellbore. Steam injection may be followed by immediate production or by closing the well (called the soak phase) to allow even heat distribution before production is begun. The cycle of injection, soak, and production is repeated as long as the oil yield is profitable. Also called steam soak and huff n puff.

n: an acidizing treatment using low or no pressure to improve the permeability of a formation with fracturing it. See wellbore soak. Compare fracture acidizing.

acidizing a rock below the fracturing pressure, either to reduce the formation damage or to improve the initial permeability.

n: it usually refers to thethe activity difference between water in heaving shale and the liquid phase of fluid that caused soak and hydration, which caused the volume of shell becomes large.

n: a cylindrical or spherical device that is affixed to the end of a wireline just above the hook to keep the line straight and to provide weight. v: to soak metal pieces in a chemical solution to remove dirt and scale from the metals surface.

a chemical treatment of the tubulars to remove pipe dope, mill scale and mud or cement residue.

n: Pump crude oil into the well and make it reach the free piont ,the friction coefficient can be remedied under the soak of the oil ,as a rusult,the unfreezing can be completed

allowing a solvent to be in contact with a deposit for a period of time.

n: in cyclic steam injection, the period between the steam injection phase and the production phase.

n: see cyclic steam injection.

n: The fluid used to soak struck point and free struck after sticking .
