Enhancing shale gas reservoir characterization using hydraulic fracture microseismic data

Shale gas has more than doubled the natural gas reserves in North American, according to estimates by IHS CERA, adding 1200 tcf of shale gas in the US and 500tcf in Canada. Knowledge gained in North America during the last few decades is now being used to benefit the increased interest in shale gas around the world. Collecting and integrating different sources of knowledge about shale reservoirs is the key to gaining competitive advantage by avoiding non-productive acreage, selectively drilling the ‘sweet spots’ and effectively stimulating the wellbore. Surface geological studies and high quality 3D seismic data provide valuable field-wide data before development drilling. Hydraulic fracturing results in microseismic events that can be recorded at the surface or from monitor wells to locate and help characterize the fractures. This case study shows how microseismic data can be a useful part of the mix of geotechnical information sources that, when combined, provide valuable information about shale gas reservoirs.
