In 2010, a black-oil reservoir was discovered in Kuwait with a pressure of 4100 psia and a temperature of 200F. The reservoir started producing 52,000STB/d of 36API oil and 32.24 MMSCF/d of 0.72 gravity gas. By 2017, the reservoir pressure had dropped to 3400 psia and the reservoir was producing 13,200STB/d of oil and 8184MSCF/d of gas. The gravities of the produced oil and gas did not change during the 7 years of production. Also, the cumulative production from the reservoir reached 8.8 million STB of oil and 5,456 MMSCF of gas. If the reservoir's pore volume and water saturation are constant, what is the reservoir's IOIP in STBs? Hint: Cumulative produced oil =IOIP Oil remaining (all in STBs)
