Natural fractures are very common in shale gas plays. \; It is often presumed that because t he formations are so tight, gas can be produced economically only when ext ensive networks of natural fractures exist. \; The creation of large f racture surface area in contact with the reservoir is regarded as essentia l to commercial success. \; This is facilitated by multi-stage hydraul ic fracturing of long horizontal wells using large volumes of low-viscosit y (low-cost) fracturing fluid.  \;The fracture systems that are create d by this process are indeed large and often complex, due essentially to i ntersection of the hydraulic fractures with the natural fracture network.  \;However, the efficiency of this process in terms of water usage is now coming under close scrutiny, not least because of growing environmenta l concerns. \;
The success of these operations is beyond doubt, but what can be inferred about the accuracy of this conceptual picture in light of many years&rsquo\; accumulated production data? \; What does production data tell us about the role of natural fractures, whether init ially closed (mineralized) or open, in the production process? \; This presentation addresses these issues by using a semi-analytic shale gas pr oduction model to analyze and interpret production data from many shale ga s wells across several different plays. \; Among the many inferences t hat can be drawn from the results of this investigation is a fresh apprais al of the role of natural and hydraulic fractures in the production proces s.
