Q. In an oil well, the pressure at the gas oil contact (GOC) at a depth of 2000 m is 205 bar (gauge), as shown in the figure. The static oil pressure gradient is 0.08 bar/m in the pay zone. If a constant hydrostatic pressure gradient of 0.1 bar/m prevails throughout the subsurface, then the
Q. A pressure build-up test was conducted in a well after 1000 days of producing oil at a constant rate of 0.01 reservoir-m3/s. The two shut-in bottom-hole pressure readings taken at 0.5 day and 1 day after shut-in are 150 × 105 Pa and 151 × 105 Pa, respectively. These pressure points correspond to the
