TL;DR: In this paper, the static and dynamic elastic properties of shale gas reservoir rocks from Barnett, Haynesville, Eagle Ford, and Fort St. John shales through laboratory experiments were studied.

TL;DR: In this article, the authors utilized an integrated permeability and porosity measurement system to measure the stress dependent porosity of Pliocene to Pleistocene sedimentary rocks from a 2000m borehole.

TL;DR: In this paper, the authors studied the elastic moduli, ductile creep behavior, and brittle strength of shale-gas reservoir rocks from Barnett, Haynesville, Eagle Ford, and FortSt. John shale in a series of triaxial laboratory experiments.

TL;DR: In this article, the effect of time-dependent deformation on the in situ differential stress in shale gas reservoir rocks was evaluated using linear viscoelastic theory and using laboratory constrained constitutive parameters, which indicated that a significant proportion of a differential stress change would be relaxed over time-scales on the order of days.

TL;DR: The retrieved cores from the Taiwan Chelungpu-fault Drilling Project are presented and the main slip zone associated with the Chi-Chi earthquake is identified and the surface fracture energy estimated from grain sizes in the gouge zone of the fault sample was directly compared to the seismic fracture energy determined from near-field seismic data.
