Special Core Analysis Laboratory (SCAL) Measurements Can be Used to Verify Wireline Petrophysical Analyses


Petrophysical analysis of wireline data from this high permeability, high gravity, high energy clastic reservoir estimated residual oil saturation (Sor) of approximately 7 %.  SCAL capillary pressure measurements and the above Leverett J-Function analysis convinced a skeptical reservoir engineering staff that very high recovery factors and, consequently, low Sor, were possible.

How May I Help You Plan and Analyze Your SCAL Program to Provide More Accurate Reserves Estimates?
