Example 7.1-Analysis of a Flow-After-Flow Test. Estimate the initial stabilized AOF potential of a well \\( { }^{10} \\) having the well and reservoir properties listed below. Use both the Rawlins-Schellhardt and the Houpeurt analysis techniques. In addition, estimate the AOF potential 10 years later when the static drainage area pressure has decreased to 350 psia. Evaluate the AOF potential at \\( p_{b}=14.65 \\) psia. Table 7.3 summarizes the flow-after-flow test data. \\[ \\begin{aligned} \\gamma_{g} & =0.715 . \\\\ L & =3,050 \\mathrm{ft} . \\\\ r_{w} & =0.5 \\mathrm{ft} . \\\\ M_{a} & =20.71 \\mathrm{lbm} / \\mathrm{lbm}-\\mathrm{mol} . \\\\ A & =640 \\mathrm{Ac} . \\\\ \\phi & =0.25 . \\\\ T_{f, w f} & =90^{\\circ} \\mathrm{F} . \\\\ C_{A} & =30.8828 . \\\\ h & =200 \\mathrm{ft} . \\end{aligned} \\] Current \\( \\bar{p}=407.6 \\) psia, \\( p_{p}(\\bar{p}=407.6)=1.6173 \\times 10^{7} \\mathrm{psia}^{2} / \\mathrm{cp} \\). \\( \\bar{p} \\) after 10 years \\( =350 \\) psia, \\( p_{p}(\\bar{p}=350)=1.2239 \\times 10^{7} \\mathrm{psia}^{2} / \\mathrm{cp} \\). \\( p_{b}=14.65 \\mathrm{psia}, p_{p}\\left(p_{b}\\right)=2,674.8 \\mathrm{psia}^{2} / \\mathrm{cp} \\).
