Well Log Interpretation

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

$h_{gross} = \Sigma h_{gross}$

$h = \Sigma h$ 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

$h_{gross}$ = Gross thickness, m2

$h$ = Net pay, oil saturated thickness, m

$\phi$ = Porosity, fraction or %

$S_o$ = Oil saturation, fraction or %
