Using Artificial Lifts in the Oil Fields

Using Artificial Lifts in the Oil Fields

• Artificial lifts are used when the natural
  energy of a reservoir isnt strong enough to
  drive oil to the surface. They basically work by
  increasing pressure, which pushes oil up and
  leads to better production. Natural pressure can
  cause oil to flow freely, but that energy usually
  wanes over time, leading to the need for some
  artificial assistance. Artificial assistance
  comes in several forms, but the most common
  assistance is the use of pumping systems. Below
  are four types of pumps and how they provide
  artificial lifting in oil fields.

Dual Action with Hydraulic Pumps

• Generally, hydraulic pumps consist of two
  stacked pistons that are connected by a moving
  rod. These pumping systems are comprised of
  surface and subsurface pumps and powered by clean
  or power oil from the well where theyre
  installed. Theyre usually connected by tubing
  string. Power oil is moved through this tubing
  string from the surface pump to the subsurface
  hydraulic pump then oil is pushed through a
  parallel tubing string and up to the surface.

Ever Popular Beam Pumps

• Beam pumps are the most common type of
  artificial lift system and the most common type
  of jack pump found on onshore oil wells. These
  pump systems consist of a sucker rod pump and a
  rod string and have pumps on and below the
  surface to increase pressure and force the oil
  up. The pumps are powered by a prime mover or
  electric gas engine.

• Above the surface, the beam pump is
  connected to sucker rods that dive into the
  wellbore. The beam pump pistons back and forth to
  move the pump, sucker rods and rod string.
  Because of this action, the pump can lift the oil
  through the reservoir, the well and finally, to
  the surface.

Emerging Gas Lifts

• The gas lift is an emerging pumping system
  that involves using a lift to inject recycled
  compressed gas into a well to reduce pressure.
  Note This recycled gas comes from the well.
  Pressure at the bottom of the well is reduced
  when the injected gas decreases the viscosity of
  all the liquids in the well. A reduction in
  pressure allows oil to flow freely to the
  surface. Its a system thats most often suitable
  for offshore oil pumping applications.

The Powerful Electric Submersible Pump

• Electric submersible pumps are powerful,
  mass producers that can lift 25,000 barrels of
  oil a day. In these systems, the pump is
  connected to an electric motor and a centrifugal
  pump is installed in the reservoir below the
  fluid level. The entire system is connected at
  the bottom of a tubing string. Impellers or
  blades on the pump shaft spin and put pressure on
  oil in the well, forcing it to rise.
