Crude Oil Treatment

Crude oil is processed for the purposes of:

  • separating the gas phase (associated gas) from the produced fluid
  • separating formation water from the produced fluid
  • reducing the content of mechanical impurities in the produced fluid
  • other treatment requirements

All of these activities are accompanied by a reduction in pressure of the fluid being produced from reservoir pressure to the pressure existing in storage tanks (usually atmospheric pressure).  The primary objective is to ensure that the quality of the crude oil meets the technical terms of delivery. The entire process of oil treatment, including its transport from reservoir to shipment tank, takes place in a hermetically sealed system.
