A fully-coupled highly-parallelized geomechanical simulator for assessing induced seismicity

Jean-François Molinari, Brice Tanguy Alphonse Lecampion, Guillaume Anciaux, Nicolas Richart, Emil Gallyamov

Induced seismicity caused by anthropogenic modification of the subsurface effective stress state has been observed in a number of industrial applications -- from hydrocarbon extraction (e.g., Groningen [1]), drilling waste-water disposal (e.g., [2]) to the ...

Elastic behavior of partially saturated gas shales during unloading - reloading cycles in uniaxial compression

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Elastic properties of gas shales are of utmost importance for the exploitation of shale gas reservoirs. Static elastic properties are usually measured by performing unloading-reloading cycles in uniaxial or triaxial compressive tests. The response of gas s ...

Hydro-mechanical characterization of gas shales and Opalinus Clay shale in partially saturated conditions

Alberto Minardi

An experimental study on the behaviour of shales in partially water saturated conditions is presented in this thesis. The Opalinus Clay shale and gas shales from different unconventional reservoirs have been studied. Opalinus Clay is currently considered a ...

Gas Shales Testing in Controlled Partially Saturated Conditions

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Laboratory measurement of mechanical properties of gas shales represents a challenging topic in geomechanics due to their peculiar features such as heterogeneity, anisotropy, low permeability, and complex physical phenomena related to the hydro-mechanical ...

Nonlinear elastic response of partially saturated gas shales in uniaxial compression

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Elastic properties of gas shales are fundamental for the geomechanical characterization of unconventional reservoirs. Due to the presence of microcracks, a non-linear elastic behaviour with hysteresis is usually exhibited when gas shales are subjected to u ...

Controls on subsurface methane fluxes and shallow gas formation in Baltic Sea sediment (Aarhus Bay, Denmark)

Sabine Flury McGinnis

Shallow gas accumulates in coastal marine sediments when the burial rate of reactive organic matter beneath the sulfate zone is sufficiently high and the methanogenic zone is sufficiently deep. We investigated the controls on methane production and free me ...

An Insight into the Fluid Retention Capabilities of Shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The hydro-mechanical behaviour of shales is becoming one of the most important issues in modern geomechanics, largely driven by petroleum industries (i.e., the extraction of shale gas), the sequestration of CO2 and the nuclear waste geological storage. In ...
