2. (25 points) A water-drive reservoir has the following boundary-pressure history: Time (months) Boundary pressure (psi) 0 6 12 18 24 2610 2600 2580 2552 2515 The aquifer-reservoir system is characterized by the following data: Reservoir 2000 radius, ft h, ft k, md $,% μι, cp Cw, psi- CI, psi-1 25 60 17 0.55 0.0000007 0.0000002 Aquifer 00 30 80 18 0.85 0.0000008 0.0000003 If the encroachment angle is 360°, calculate the water influx at times of 6 months, 12 months, 18 months, and 24 months by using the van Everdingen-Hurst method.
