Homework Four There is an exploration well A which produces 300 cm /s. After the well works for 1.3 X 10's, a new well B starts to produce 600 cm/s, and the new well is 105 cm away from the first well. The filtration process is non-steady state flow. We already known that K= (Last two digits of your ID um?, h=1200 cm, Ct=1.8 X 10-5 atm', M=9 mPa.s, r, = 10cm. H。 元 X м M Well A M Well B (1) Calculate the pressure drop of the M point (at the middle of well A and B) after well A producing 2.6X 106s later. (For students last digit of your ID is 1, 4 or 9). (2) Calculate the pressure drop of the M point (a quarter away from well B) after well A producing 2.6 X 10's later. (For students last digit of your ID is 2,6,8 or 0). (3) Calculate the bottom hole pressure drop of the well B after well A producing 2.6X 106s later. (For students last digit of your ID is 3, 5 or 7).
