Question 2
Given the well data in Appendix A (see last page), and assume a 40 acre drainage area, calculate:
a. The time required to reach pseudosteady-state.
b. The flow rate for transient flow from time=0 to time to pseudosteady-state at wellbore
flowing pressures ranging from 0 to initial reservoir pressure. Display 5 equal
increments for time and 10 for wellbore flowing pressure. Plot the corresponding IPR
c. The flow rate for pseudosteady-state, if the flow boundary pressure equals the initial
reservoir pressure and the wellbore flowing pressure is 500 psi.
d. The IPR curve for a reservoir at pseudosteady-state condition with average reservoir
pressure equal to 5000 psi at the time of transition. Repeat for average reservoir
pressure of 4500 and 4000 psi.
