3. Given a well in an infinite-acting reservoir, having the following properties: Viscosity =0.7cp Ct=2e5psi1B=1.13RB/STBrw=0.333ftk=7.5mds=3h=25ftpi=3000psiPorosity=20%q1=100STB/Dq2=0STB/Dt1=1000hourst2=1010hours The well produces for 1000 hours at 100STB/D, and is then shut-in. Calculate and plot the pressure at r=1010 hours as a function of r on semi-log graph paper (put r on the logarithmic axis) using superposition in time and the Ei solution (or its logarithmic approximation) for r=0.5,1,2,5,10,20,50,100,200,500,2000, and 10000 feet
