formation binding agents (calcite, clay, silica overgrowth, heavy oil, etc.) that hold the formation grains together.

cold heavy oil production with sand.

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: oil composed mainly of heavy ends.

lower gravity, often higher viscosity oils. Normally less than 28o API gravity.

matrix breakthrough event.

n: 1. a sandstone that yields oil. 2. (by extension) any reservoir that yields oil, whether or not it is sandstone.

n: 1.In the context of heavy oil, an oil sand is a porous rock layer, often considered to be a mixture of sand, clay, water, and bitumen. The term is predominantly used in Canada, where over 170 billion barrels of bitumen are estimated to be held by large oi

payzone, usually produces oil in economic quantities.

A deposit of heavy oil, usually with API gravity less than about 18o. May have sand content of 50%.

n: a type of improved recovery in which heat is introduced into a reservoir to lower the viscosity of heavy oils and to facilitate their flow into producing wells. The pay zone may be heated by injecting steam (steam drive) or by injecting air and burning a portion of the oil in place (in situ combustion). See cyclic steam injection, in situ combustion, steam drive.

an enhanced oil recovery process that uses heat to reduce oil viscosity.
