... Abstract XJN field has implemented water injection as pressure maintenance since 1987, only one year after initial production. XJN is carbonate reservoir with weak aquifer underlying the oil zone. Initial reservoir pressure was 2,700 psi and peak production was 27,000 BOPD. Reservoir pressure...

For example, at 1,700 psi reservoir pressure, the well was producing 900 bopd at a drawdown of 900 psi which was more than half of the reservoir pressure. The low productivity index trait was observed in all...
