THREE-DIMENSIONAL MODELING OF HYDRAULIC AND NATURAL FRACTURE INTERACTIONS AND ITS APPLICATIONS IN RESERVOIR STIMULATION
… of the unconventional and geothermal reservoirs can be increased for economic production by hydraulic fracturing. Natural fractures and other discontinuities are inseparable elements of unconventional reservoir rock masses. During stimulation, hydraulic fractures often interact with …

Feasibility study of sedimentary enhanced geothermal systems using reservoir simulation
… geothermal projects, from a sedimentary reservoir with low permeability that requires productivity enhancement, using numerical reservoir simulation. The performance of a sedimentary geothermal reservoir is investigated in terms of reservoir hydraulics and thermal evolution. To build a …

Physical Optimization of Acid Fracturing with Unified Fracture Design
Acid fracturing is a reservoir stimulation technique where a fracture is created by injection of acid into the reservoir instead of conventional proppant slurry. The acid causes differential etching on the fracture walls, creating asperities. These asperities hold up the fracture wall, thus …

Imaging a Hydraulically Fractured Bakken Shale Reservoir Using 4D-Tomography and Reverse VSP Techniques with Perforation Shot Sources
Hydrocarbon production from shale reservoirs varies considerably from one location to another in the same well. This variation can be due to geologic factors but also due to variabilities in the reservoir’ stimulation. Seismic images may be inconclusive in identifying areas where hydraulic …

Hydrothermal spallation drilling and advanced energy conversion technologies for Engineered Geothermal Systems
… their impact, as well as the impact of advanced reservoir stimulation technologies, on EGS levelized electricity costs. A technical analysis of geothermal binary Rankine cycle surface power plants was also performed to determine the effect of novel working fluids on plant efficiency for both sub- …

Geomechanical Reservoir Model Calibration and Uncertainty Assessment from Microseismic Data
Hydraulic stimulation of low permeability rocks in unconventional reservoirs has been observed to trigger microearthquakes (MEQs). Triggering of the MEQ events has been linked to the pore pressure, temperature, and in-situ stress variations which result in crack initiation. The resulting clouds of …

Investigation of changes in permeability due to poro-thermo-elastic effects in enhanced geothermal reservoirs
… due to poro-thermo-elastic effects during stimulation and circulation of cold water over a longer term in geothermal reservoirs is presented. A hybrid of tectonic simulation and stochastic analysis of field data is utilized to generate the subsurface fracture map of three formations. For …

Crustal stress variability across spatial scales - examples from Canada, Northern Switzerland and a South African gold mine
… in the underground (boreholes, tunnels, caverns, reservoir management, etc.) have a large impact on the stress state. It is important to assess, whether these activities may lead to (unpredictable) hazards, such as induced seismicity. Equally important is the understanding of the in situ stress …
