RI 4715 Helium Tracer-Gas Studies In The Cabin Creek, W. Va. Oil And Gas Field

Helium used as a tracer gas in petroleum reservoirs continues to show great promise as a new tool for the oil and gas industry, according to tests conducted jointly by the Bureau of Nines and The Pure Oil Co. in-the Cabin Creek field, Boone and Kanawha Counties, W. Va. Helium, when used as a, tracer gas, is mixed with natural gas being injected into a reservoir for secondary recovery of oil, recycling, pressure-maintenance, or other purposes. Three separate experimental helium tracer-gas tests were run in the Cabin Creek, W. Va., field, wherein helium was added as a tracer to the natural gas that was being injected into the oil-bearing Berea sandstone. The results obtained in each test permitted determining the direction and rate of travel of the injected gas, calculating the volume of injected gas in the gas produced at the various wells, and determining the nature of the transition from natural gas to injected gas during a gas-injection program. Data were obtained on the effects obtained from waves of injected gab containing 1 percent and containing 5 percent helium and from a wave of essentially pure helium injected into the formation.
