... Abstract EXCO-North Coast's has conducted pilot tests to add incremental reserves in a thin Marcellus through a contrarian approach toward stimulating that shale. In these underpressured Jackson County, West Virginia shale wells, slickwater fracture stimulations were used instead of the more...

... Abstract Microseismic monitoring of hydraulic fracture stimulation treatments has done much to diminish the expectation of engineers and geoscientists that symmetrical bi-wing fractures extending away from the well bore from as a result of the treatment. Mapping of microseismic event locations...

... Abstract Creating an optimum hydraulic fracture to produce gas from nano-darcy shale uses much different technology than that commonly used in low permeability sandstone or carbonate reservoirs. Potentially productive natural fracture pathways are often present but thought to be seldom open...

... in so-called traditional tight gas reservoirs. This production management problem is exacerbated by the plasticity of shale reservoirs, the need for extensive natural fracture swarms and the now common practice of multiple fracture stimulations of the long-reach laterals. This paper examines three data...

... Abstract Ultra-low permeability shale reservoirs require a large fracture network to maximize well performance. Microseismic fracture mapping has shown that large fracture networks can be generated in many shale reservoirs. In conventional reservoirs and tight gas sands, single-plane fracture...

... Abstract In this work we present the current status of production evaluation and prediction for shale gas reservoirs. We focus primarily on the effect of wellbore geometry (vertical vs. horizontal) and fracture stimulation, and consider only relatively simple shale reservoir characteristics...
