.... Understanding rock mass response to the stimulation treatment allows to design effective treatment while mitigating unwanted seismicity. Shearing on a plane of weakness near the stimulated volume can be inhibited or promoted by change in poro- and thermo-elastic stress, while pore pressure increase tends...

... hydraulic fracture stimulation treatment, and production borehole were implemented while reservoir conditions were maintained throughout. The initial reservoir was found to give sub-optimal production rates but the execution of a new low-volume overcritical pressure pulse (LVOP) stimulation treatment...

... tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source...

... tests provided a comparison of fracturing between water and foam. A downhole pressure gauge was used during the stimulation treatment. Figure 6 summarizes the lithology of the rock units near the coal seam and the corresponding relative stresses as measured with mini-frac techniques. A 4 foot (1.2 m...
