For the following gas reservoir offshore Louisiana, ${?}^{23}$ esti$-$

mate the original gas in place and formation compressibility

using the material$-$balance method for geopressured reser$-$

voirs. In addition, use the material$-$balance method present$-$

ed for a normally pressured gas reservoir, and compare the

initial gas estimates from both cquations. The plotting func$-$

tions are tabulated in Table $10\mathrm{.}24.$
