We model oil price dynamics in a general equilibrium production economy with two goods: a consumption good and oil. Production of the consumption good requires drawing from oil reserves at a fixed rate. Investment necessary to replenish oil reserves is cos ...
When large volumes of fluids are removed from or injected into underground formations for, e.g., hydrocarbon and water production, CO_2 storage, gas storage, and geothermal energy exploitation, monitoring of surface deformations coupled to numerical modeli ...
Despite ongoing engineering efforts, unconventional horizontal gas wells completed with the multi-stage hydraulic fracturing technique are not yet producing to their full potential, as a meaningful proportion of clusters are producing marginally - if at al ...
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 ...
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 ...
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 ...
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 ...
The constitutive modeling of shales is an important topic in the geomechanics community as it is often encountered in advanced applications such as nuclear waste storage, CO2 sequestration, and unconventional oil and gas exploitation. The goal of this work ...
Natural gas is defined as a combustible mixture of hydrocarbons coming from ground deposits and it is mainly used as a source of energy for burners and motors. Its consumption is increasing worldwide, as this represents a cheap and abundant source of energ ...
Microbial enhanced oil recovery (MEOR) depends on the in situ microbial activity to release trapped oil in reservoirs. In practice, undesired consumption is a universal phenomenon but cannot be observed effectively in small-scale physical simulations due t ...
