For laboratory experiments, shale samples were used in most cases in order to represent the real pore structure and distribution in the reservoir...

...S.A. Holditch; W.J. Lee; D.E. Lancaster; T.B. Davis Summary This paper shows that mud-filtrate invasion prior to drillstem testing in low-permeability gas formations can cause significant reduction of gas flow rate observed during the test. In addition, apparent gas permeabilities determined from...

...K. Sampath; C. William Keighin Summary The gas permeability of some sandstones from Uinta County, UT was measured in the laboratory. The effect of confining pressure and partial water saturation on gas permeability was investigated. Measurements were conducted at pressures of up to 34.5 MPa...

...Joel D. Walls; Amos M. Nur; Thierry Bourbie Summary Effective permeability to gas with various degrees of brine saturation has been measured in the laboratory for several very tight sandstones from the Spirit River formation of Alberta, Canada. Gas permeability as low as 20 × 10 -9 darcy...

Vairogs et al . 3 concluded that very low-permeability rocks are affected by stress to a greater degree than those having higher levels of permeability. This agreed with results reported earlier by McLatchie et al . 4 Tannich 5 mathematically...

...D.E. Simon; F.W. Kaul; J.N. Culbertson The Morrow-Springer formation is characterized by seven reservoir rock lithologies. Laboratory studies, including regained-gas permeability, SEM, petrographic, and X-ray diffraction, indicate that certain treatment fluids petrographic, and X-ray diffraction...

...Rex D. Thomas; Don C. Ward Research conducted to determine the potential of nuclear explosions to stimulate gas production verifies that the gas permeability of tight sandstone cores is markedly decreased with increasing overburden pressure. Water saturation also reduces the gas permeability...

...John M. Goode Permeabilities of cementing compositions have become of increasing interest during the last few years due to the growing use of underground reservoirs for gas storage. This paper presents data on water permeabilities and limited data on gas permeabilities for some of the more common...

The resultantdata can be applied to other systems of interest because the gas permeabilityin the gas-oil system is the permeability of the nonwetting phase and, as such, is equivalent to the gas permeability in the gas-oil...
