Full Description

2016-17 SPE Distinguished Lecturer

Natural fractures are very common in shale gas plays.  It is often presumed that because the formations are so tight, gas can be produced economically only when extensive networks of natural fractures exist.  The creation of large fracture surface area in contact with the reservoir is regarded as essential to commercial success.  This is facilitated by multi-stage hydraulic fracturing of long horizontal wells using large volumes of low-viscosity (low-cost) fracturing fluid.  The fracture systems that are created by this process are indeed large and often complex, due essentially to intersection 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 environmental 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’ accumulated production data?  What does production data tell us about the role of natural fractures, whether initially closed (mineralized) or open, in the production process?  This presentation addresses these issues by using a semi-analytic shale gas production model to analyze and interpret production data from many shale gas wells across several different plays.  Among the many inferences that can be drawn from the results of this investigation is a fresh appraisal of the role of natural and hydraulic fractures in the production process.
