n: the injection of air or gas into a liquid. In the oil industry a common form of aeration is the injection of natural gas into reservoir liquids standing in a well. Aeration with natural gas reduces the density of the liquids and allows declining reservoir pressure to lift the liquids. See gas lift.

n: The technique of injecting air or gas in varying amounts into a drilling fluid for the purpose of reducing hydrostatic head. See also Air Cutting.

intoduction of air.

n: 1.the injection of air into a reservoir in a pressure maintenance or an in situ combustion project. 2. the injection of fuel into the combustion chamber of a diesel engine by means of a jet of compressed air.

large scale injection of pH>7 fluids. The basic materials may react with oils to form reactants that can reduce viscosity or affect wetting.

Injection of fluids down the annulus or “backside”. Common as a gas supply path for gas lift. Also used in some fracturing operations, to spot fluids downhole when no packer is used or a type of injection valve is in the tubing to allow entry of chemicals

return flow from injection of a fluid into a formation.

v: to reverse the flow of fluid from a water injection well to get rid of sediment that has clogged the wellbore.

v: The verb form of backwashing.

n: in corrosion control, the injection of a quantity of chemical corrosion inhibitors into the lines of a production

bottom hole injection pressure.

n: See cementing.
