Assume a well is located at the center of the right half of a closed$-$square reservoir. Given the

rock and fluid properties and the pressure$-$buildup test curve given below, estimate the average

drainage$-$area pressure using:

a$)$ the Dietz. $(10$ points$)$

b$)$ MBH methods. $(15$ points$)$

qo $=350$ STBD Bo $=1\mathrm{.}25$ RB$/$STB rw $=0\mathrm{.}25$ ft

h $=60$ ft A$=50$ acres tp $=2160$ hrs

ct $=1$ x $10-5$

psi$-1=0\mathrm{.}21=2$ cp

$(1$ acre $=43560$ ft$2$
