Fracture imaging study in the Carthage Gas Unit, Panola County, Texas, USA is shown that microseismic events induced by hydraulic fracturing at a depth of 9,500 ft were detected at distances exceeding 1,300 ft from the origin. An industry consortium of major operators, service companies, government agencies and national laboratories was formed to perform a more detailed study using 96, 3-component geophone sondes distributed among two monitor wells. A unique microseismic recording system specifically designed and manufactured for these operating depths is presented. Applications of the technology include optimization of hydraulic fracture designs and accurate mapping of fracture geometry.
