Analysis of fluid injection-induced fault reactivation and seismic slip in geothermal reservoirs
We explore the issue of fault reactivation induced in enhanced geothermal systems by fluid injection. Specifically, we investigate the role of late stage activation by thermal drawdown. A Thermal-Hydrological-Mechanical simulator incorporating a ubiquitous joint constitutive model is used to systematically simulate the seismic slip of an embedded critically stressed strike-slip fault. We examin...
متن کاملHydrogeologic controls on induced seismicity in crystalline basement rocks due to fluid injection into basal reservoirs.
A series of Mb 3.8-5.5 induced seismic events in the midcontinent region, United States, resulted from injection of fluid either into a basal sedimentary reservoir with no underlying confining unit or directly into the underlying crystalline basement complex. The earthquakes probably occurred along faults that were likely critically stressed within the crystalline basement. These faults were lo...
متن کاملTHE eFFECTS OF ADSORPTION ON INJECTION INTO GEOTHERMAL RESERVOIRS
The effects of an adsorbing phase on the injection of liquid and eventual production of vapor from a lowporosity, vapor dominated geothermal reservoir was studied. The magnitude of delay caused by adsorption, diffusion partitioning, preferential partitioning, and permeability variation were compared. Results were then compared to measured tracer production data at the Geysers to determine the m...
متن کاملLaboratory experiments simulating poroelastic stress changes associated with depletion and injection in low-porosity sedimentary rocks
We characterized the poroelastic deformation of six cores from three formations associated with the Bakken play in the Williston Basin (the Lodgepole, Middle Bakken, and Three Forks formations). All are low-porosity, low-permeability formations, but vary considerably in clay, kerogen, and carbonate content. The experimental program simulated reservoir stress changes associated with depletion an...
متن کاملDisplacement Fields of Sedimentary Layers Controlled by Fault Parameters: The Discrete Element Method of Controlling Basement Motions by Dislocation Solutions
In the two-dimensional discrete element modeling of displacement of sedimentary layers caused by faulting within the basement, we attempted to move a rigid basement as if it were an elastic basement by controlling its motion through application of dislocation solutions. An advantage of our modeling procedure is that we can discuss displacement fields of sedimentary layers in connection with fau...
