Brief
Well Log Interpretation is a summary of a well log. Used in Mature Water Flood Analysis for calculating HCPV for Blocks and Patterns.
Summary Equations
where Saturation=Oil
where Saturation=Oil
where Saturation=Oil
where
= Gross thickness, m2
= Net pay, oil saturated thickness, m
= Porosity, fraction or %
= Oil saturation, fraction or %
Example
Calculate the summary of the well log interpretation above for the Б2(С1) reservoir.
