solve a and b. thanks

(a) Calculate the average reservoir pressure (p) that can be expected in a field with one producing well. The estimated drainage radius for the producing well is 1,100ft and the well is producing under semi-steady state condition. Following are various reservoir parameters that were observed in the field. qoSBookhrwpwf=250STB/day(constant)=+8=1.15bbl/STB=2.5cp=50md=100ft=0.333ft=3,000psi (10 points) (b) Using the reservoir properties, as shown above, and other relevant information given below, calculate the corresponding dimensionless time tD and dimensionless pressure pD for a well test that was performed in the well mentioned in part (a). tct=15.33hrs=4.2106/psi=15%
