... system, and a third trial well was pumped at a higher injection rate to increase stimulated reservoir volume. Unfortunately, no trial wells continuously produced at a stable gas rate, so the completion and fracturing design was further modified and tested. It was hypothesized that the optimal solution...

... stimulation schedule, average productivity is expected to increase up to five folds compared to an un-fractured well. For the upper reservoir, which has a relatively low permeability, cumulative production after fracturing treatment will continue to increase up to three years after which, the production rate...

... to stress) impacts the propagation complexity of hydraulic fractures from the direction of maximum principal stress. In general, this paper highlights the benefit of incorporating the three- dimensionality of key geomechnical parameters when designing hydraulic fracturing stimulation treatments. 2 URTEC...

... the written consent of URTeC is prohibited. Abstract In the past three years, some moderate-sized earthquakes (MW>4.0) took place in the southern Sichuan Basin, China and were suspected to be associated with hydraulic fracturing stimulation for producing the shale gas. The objective of this study...

... Abstract Stress-dependent permeability in coal seam gas (CSG) reservoirs can challenge the development of coal fields with lower initial permeabilities. Thus, advanced well stimulation techniques become essential. This work evaluates the performance of novel graded proppant injection (GPI...

... Shale gas plays require technology such as fracture stimulation to increase rock permeability and achieve commercial rates of flow. The brittleness of shales are a major control on the ease of fracture stimulation. The Brittleness Index (BI) is a proxy for rock strength, based on geomechanical...
