Unconventional Reservoir Geomechanics

Conventional geomechanics cannot provide suitable modes of behavior and performance for today?s unconventional reservoirs such as the evolution of porosity-permeability relationships with multiphysics coupled effects, which ultimately help determine production rates. Unconventional Reservoir Geomechanics delivers a reference that discusses a variety of approaches tailored in developing geomechanical models and provides a smarter tool to predict hydrocarbon extraction specifically for unconventional reservoirs. Starting with a full explanation on a more unified theoretical framework discussing permeability characterization, the authors advance to offer a full range of new modelling solutions followed by a series of lab-scale and field-scale applications to match the history-verified models, bridging a gap for engineers to fully understand the interactions of multiple processes in field scales from theory to practice. Going a step further, other applications such as CO2 sequestration in coal seam or shale gas reservoirs are explained to illustrate how unconventional reservoir geomechanics can be extended to solve related and even more complex challenges. Combining both theoretical and practical models backed by data, Unconventional Reservoir Geomechanics gives reservoir engineers a smarter and more sophisticated tool to approach today?s more complex geomechanical modeling challenges.
