Project Final Report-09122-04-Gas Technology Institute (GTI), with funding from the Research Partnership to Secure Energy for America (RPSEA), initiated an industry cooperative research project, that, aside from other tasks, aims to examine the contribution of gas production from natural fractures in addition to predicting the spatial distribution and population characteristics of these natural fracture systems. These natural fracture systems in conjunction with hydraulic fracturing are the key drivers for gas production. Hence, in addition to understating the natural fracture attributes, it is necessary to optimize hydraulic fracturing treatments so that a synergistic effect is achieved whereby the natural fractures are exploited for enhanced gas production. As such, much of the research was focused on hydraulic fracture design and optimization with supporting field data acquisition
