...) system. Helium, which shows a minimum solubility in the SBM, was selected to simulate the downhole gas influx. The Distributed Fiber-Optic Sensing (DFOS) data was obtained in high-resolution to monitor the gas migration behavior, and the gas slip velocities, slug length, and suspension concentrations...

.... In this work, a systematic and practical pressure-pulse decay (PPD) technique is given to determine ultralow permeabilities of shale reservoir core in a cell with finite volume. The test gas can be non-adsorption gas such as helium or adsorption gas such as methane. As described herein, given appropriate...

... for permeabilities less than about 0.01 md. We validated the steady-state Klinkenberg-corrected permeabilities with liquid permeabilities measured using both brine and kerosene. Although gas slippage effects are more pronounced with helium than with nitrogen, we also confirmed the steady-state results using two...

... The Federal Government's interest in helium began with World War I when its military value as an inert lifting gas was recognized by the Army and Navy 1 . The government's initial direct involvement in helium production dates back to the passage of the Helium Act of 1925 which authorized...

...-permeability-desorption relationship was established for helium, methane and carbon dioxide. Related experiments measured coal compressibility, and volumetric changes of coal matrix with methane adsorption and desorption. The hypothesis that desorption of methane shrinks coal matrix, and results in increased...

... Abstract A windowed phase equilibrium apparatus was used to obtain equilibrium vapor and liquid-phase samples of two helium-bearing natural gases at experimental conditions ranging from approximately -50 to -275 F at pressures from 100 to 500 psia. Helium contents of the gases studied are 2.5...
