Using Artificial Lifts to Optimize Your Production

Using Artificial Lifts to Optimize Your Production
2

• When it comes to artificial lift pump
  operations, operators have two priorities. One,
  they want to increase their production. Two, they
  want to bring down the costs of doing so. In
  order to achieve both, there is a need to
  implement proper planning as a way of avoiding
  poor performance.

• Dealing with mature fields will often be met
  with challenges related to field productivity,
  and the artificial lift is a method that can be
  implemented to establish full recovery for fields
  or wells. Because there are many types of
  artificial lift systems, it is important to
  choose the best method for the job.

• The different types of artificial lift
  systems can be separated into two categories
  pump-assisted process and gas-assisted process.
  Positive displacement pumps (or PDPs) under the
  pump-assisted process include carbon fiber rod
  pumps, progressive cavity pumps and others have
  fixed quantities of fluids in a cavity and forced
  to move in a designed direction.

5

• Meanwhile, electrical submersible pumps or
  ESPs allow for unfixed quantities of fluids for
  displacement. With gas lifts, the injected gas
  lessens the density of reservoir fluid and thus
  decreases hydrostatic pressure, letting the
  produced fluid flow right out to its surface.

6

• With the differences, it is important to
  understand that optimizing production using
  artificial lifts will tap on the following
  things
• - Accurate data collection
• - Correct predictions of rates of production
• - Downhole volumes
• - TDHs, or total dynamic head determination
• - Right selection of surface and downhole
  equipment

7

• The different types of artificial lift
  methods will require considerations of
  applications for depth as well as temperature.
  These two things are considered as limiting
  factors for different PCP applications, though it
  is capable of lifting denser fluids. What one
  needs to take note of is to fully understand how
  each of the characteristics of artificial lifts
  will impact performance when on the job.

8

• As one will see, there is interdependence
  between production optimization and cost
  reduction for artificial lift systems. It is only
  through proper planning of a strategic design
  that is fully grounded on the individual well
  characteristics with the practical operational
  capabilities of a lift system.

9

• Choosing which is the most ideal artificial
  lift system for wells will also involve factors
  such as bottom hole pressure, amount and type of
  fluid that will be produced, wellbore geometry,
  surface location (offshore or onshore), and the
  total depth of the well. Planning carefully and
  utilizing all the information about all the known
  factors will definitely yield better results than
  the usual habit of doing things the usual way
  even when there are clear opportunities for
  innovation.
