19 (a) Plot pressure versus radius on both linear and semilog paper at 0.1,1.0, 10 , and 100 days for pe=2500 psia, q=300 STB/day; B0=1.32 bbUSTB; =0.44cp;k=25md;h=43ft;ct=18106psi1;=0.16. (b) Assuming that a pressure drop of 5 psi can be easily detected with a pressure gauge, how long must the well be flowed to produce this drop in a well located 1200 ft away? (c) Suppose the flowing well is located 200ft due east of a north-south fault. What pressure drop will occur after 10 days of flow, in a shut-in well located 600ft due north of the flowing well? (d) What will the pressure drop be in a shut-in well 500ft from the flowing well when the flowing well has been shut in for one day following a flow period of 5 days at 300STB/ day
