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

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 ...

The impact of the volumetric swelling behavior on the water uptake of gas shale

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Water uptake of gas shales is commonly considered one of the most important factors responsible for fluid loss during flowback operations after hydraulic fracturing. Imbibition experiments cover a key role in this context to analyze the impact of several f ...

Culture based approaches, dependent and independent, for microbial community fractions in petroleum oil reservoirs

Edgard Gnansounou

Petroleum reservoir is an ecosystem having extreme environmental conditions of temperature, pressure and salinity. They possess highly anoxic conditions. Major microbial communities present in this environment include fermentative bacteria, sulphate reduci ...

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 ...
