Recovery Factory

The recovery factor(RF) defines the relationship between the hydrocarbons initially in place (HCIIP) and the ultimate recovery for the field.


       UR = HCIIP * RF [stb] or [scf]

       R = UR - CP [stb] or [scf]

       Where:

       UR is Ultimate recovery
       RF is Recovery factor
       R  is Reserves
       CP is Cumulative Production

            
 

$$ UR = HCIIP * RF $$

$$ R = UR - CP $$

Where:

  • $UR$ is the Ultimate recovery
  • $RF$ is the Recovery factor
  • $R$ is the Reserves
  • $CP$ is the Cumulative production
