Brief

Well Log Interpretation is a summary of a well log. Used in Mature Water Flood Analysis for calculating HCPV for Blocks and Patterns.

Well Log Interpretation

Summary Equations

 h_{gross} = \Sigma h_{gross}
 h = \Sigma h where Saturation=Oil
 \phi = \frac{\Sigma (h*\phi)}{\Sigma h} where Saturation=Oil
 S_o = \frac{\Sigma (h*S_o)}{\Sigma h} where Saturation=Oil

where

 A = Area, m2
 h = Net pay, oil saturated thickness, m
 HCPV = Hydrocarbon pore volume, m3
 \phi = Porosity, fraction
 S_o = Oil saturation, fraction
