A formulated oil will often have KOH (potassium hydroxide), a strong base, in small amounts, as it is an effective neutralizer used in refining petroleum. [5] Additives that perform a similar function in a motor oil include magnesium and calcium sulphonates, salicylates, and phenates. [4] These are the detergent additives mentioned previously.
Steam injection is an increasingly common method of extracting heavy crude oil. Used commercially since the 1960s, [ 1 ] it is considered an enhanced oil recovery (EOR) method and is the main type of thermal stimulation of oil reservoirs.
Then the flow on the injection well is reversed producing oil through the same injection well bore. The injection and production phases together comprise one cycle. Steam is re-injected to begin a new cycle when oil production rates fall below a critical threshold due to the cooling of the reservoir. [26]

The oil is contained in a reservoir that connects to a small oil pump in the engine, which needs to be periodically refilled. Oil injection pump on a Yamaha DX100- just behind the carburettor (visible on the left) It is the primary component of two-stroke automatic lubrication system. Amount of two-stroke oil injected by the pump depends on the ...
Water injection wells may be located on- and offshore, to increase oil recovery from an existing reservoir. Normally only 30% of the oil in a reservoir can be extracted, but water injection increases the recovery (known as the recovery factor) and maintains the production rate of a reservoir over a longer period.
Injection well used for enhanced oil recovery. Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. Whereas primary and secondary recovery techniques rely on the pressure differential between the surface and the underground well, enhanced oil ...
Air injection is now used to support the catalytic converter's oxidation reaction, and to reduce emissions when an engine is started from cold. After a cold start, an engine needs an air-fuel mixture richer than what it needs at operating temperature , and the catalytic converter does not function efficiently until it has reached its own ...
