2. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...

3. Extraction of petroleum - Wikipedia

   en.wikipedia.org/wiki/Extraction_of_petroleum

   Tertiary recovery begins when secondary oil recovery is not enough to continue adequate extraction, but only when the oil can still be extracted profitably. This depends on the cost of the extraction method and the current price of crude oil. When prices are high, previously unprofitable wells are brought back into use, and when they are low ...

4. Petroleum industry - Wikipedia

   The discovery at Oil Springs touched off an oil boom which brought hundreds of speculators and workers to the area. Canada's first gusher (flowing well) erupted on January 16, 1862, when local oil-man John Shaw struck oil at 158 feet (48 m). [18] For a week the oil gushed unchecked at levels reported as high as 3,000 barrels per day.

5. Water injection (oil production) - Wikipedia

   en.wikipedia.org/wiki/Water_injection_(oil...

   Water was filtered in the water injection filters, one duty and one on standby/backwash. From the filters water was routed to the water injection pumps. The three water injection pumps each had a capacity of 221 m 3 /hr with a differential head of 2068.5 metres (209 bar). The pumps discharged to the 3,000 psi manifold and wellheads.

6. Centrifugal extractor - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_extractor

   Fig 1. Centrifugal extractor. A centrifugal extractor—also known as a centrifugal contactor or annular centrifugal contactor—uses the rotation of the rotor inside a centrifuge to mix two immiscible liquids outside the rotor and to separate the liquids in the field of gravity inside the rotor.

7. Expeller pressing - Wikipedia

   en.wikipedia.org/wiki/Expeller_pressing

   Expeller pressing (also called oil pressing) is a mechanical method for extracting oil from raw materials. The raw materials are squeezed under high pressure in a single step. When used for the extraction of food oils, typical raw materials are nuts, seeds and algae, which are supplied to the press in a continuous feed. As the raw material is ...
