Oil and Gas Artificial Lift
Artificial lift is mainly used for providing an
additional energy. In case of oil drilling if the crude oil is not coming
outside naturally means we will apply an additional force to pump the oil from
the reservoir to the surface area. When the oil pressure reduces and it reaches
a bubble point we will think about artificial lifts. They are mainly of four
different types. First is beam pump. Here a beam is introduced and it is moving
up and down. By this to and forth movement or reciprocating movement of the
beam pump it will lift the oil upwards to the surface. The motor and pump are
placed on the surface. The second method used in the advanced stage is called
as Electrical submersible
pumping (ESP). Here the motor and pump are placed inside the reservoir. As the
motor operates the oil will enters inside the centrifugal pump by the external
pressure which is excreted by the motor. The third method is Progressive cavity
pumps (PCP). Here the pump will be inside the tube and the motor will be placed
outside. In this method we are increasing the pressure inside the reservoir and
pumping out the oil.
