Controls on the Matrix Permeability and Acoustic Velocities in Jurassic Haynesville Shale USA

Abstract

An experimental study is reported of the influence of mineralogy, microstructure, and effective pressure conditions on the permeability to argon gas and of the acoustic wave velocity in Haynesville shale, USA. Samples were prepared from slabbed core from a single well and characterised for mineralogy, porosity, density, and elastic constants. Permeabilities were measured using the steady-state flow method, the pulse transient method and the oscillating pore pressure method, and together with the acoustic wave velocities were measured over a range of confining pressures and argon gas pore pressures. Most data were collected at high effective pressures for free gas flow, while the pore pressures for the onset of slip flow (Knudsen number 10^-2-10^-1 were found to be
