  • What's new in production

    Perry A. Fischer, Editor

    Injecting water into gas. By the time this arrives at your door, BP should be starting a remarkable, first-of-its-kind project to inject seawater into the gas cap of Prudhoe Bay field to maintain reservoir pressure. More than 25 years of oil production has dropped reservoir pressure within the gravity drainage area to under 3,500 psi, down from 4,340 psi when production began in 1977. The pressure drop is averaging 25 to 35 psi/yr. The project comprises five to seven injection wells, 3.6 mi of new pipeline for transport of treated seawater to the injectors and modifications to the existing seawater treatment and injector plants. The $71 million project will recover an additional 150 to 200 million bbl.
