The overall objective of this project is to show how gas can flow from the rock matrix to natural or induced fracures and be commercially produced. Flow of gas within the rock matrix has been shown to be largely controlled by sheet-like pores at grain boundaries, which are pressure sensitive. In this quarterly report, progress is reported in the following areas of advanced core analysis of low permeability gas sands: (1) surface area measurements; (2) helium porosimetry; (3) comparison of permeabilities for preserved cores and for cores subjected to drying; (4) pore space and fractures as related to diagenesis of multiwell sandstones; and (5) imbibition behavior of tight sands. 5 refs., 8 figs.
