Formation compressibility by using hydrofrac data
Input(s)
Vs: Volume Associated to Conduct a Hydrofrac (bbl)
\(\mathrm{dVs}\): Change in Volume (bbl)
\(\mathrm{dP}\): Change in Pressure (psi)
Output(s)
\(\beta\): Formation Compressibility (psi)
Formula(s)
\[
\beta=\frac{1}{\mathrm{Vs}} *\left(\frac{\mathrm{dVs}}{\mathrm{dP}}\right)
\]
