The data below was obtained from a compressibility experiment on a core sample whose

bulk volume is $52\mathrm{.}0c{m}^3$ and initial pore volume is $8\mathrm{.}82c{m}^3.$ The sample's pore space is

initially filled with water. Estimate the sample's pore$-$volume compressibility at $1000$

and $2000-$psi net overburden pressures.

$V_{wp}$ is total water squeezed out of sample at each step.
