Title: Basin analog approach answers characterization challenges of unconventional gas potential in frontier basins
Author: Singh, Kalwant
Abstract: To continue increasing the energy supply to meet global demand in the coming decades , the energy industry needs creative thinking that leads to the development of new energy sources . Unconventional gas resources , especially those in frontier basins , will play an important role in fulfilling future world energy needs . We must identify and quantify potential unconventional gas resources in basins around the world to plan for their development . Basin analog assessment is one technique that can be used to identify and quantify unconventional gas resources that is less expensive and less time consuming . We have developed a basin analog methodology that is useful for rapidly and consistently evaluating the unconventional hydrocarbon resource potential in exploratory basins . We developed software , Basin Analog System (BAS ) , to perform and accelerate the process of identifying analog basins . Also , we built a database that includes geologic and petroleum systems information of intensely studied North America basins that contain well characterized conventional and unconventional hydrocarbon resources . We have selected 25 basins in North America that have a history of producing unconventional gas resources . These are ? ? ? ? ? ?reference ? ? ? ? ? ? basins that are used to predict resources in frontier or exploratory basins . The software assists us in ranking reference basins that are most analogous to the target basin for the primary purpose of evaluating the potential unconventional resources in the target basin . The methodology allows us to numerically rank all the reference basins relative to the target basin . The accuracy of the results depends on the descriptions of geologic and petroleum systems . We validated the software to make sure it is functioning correctly and to test the validity of the process and the database . Finding a reference basin that is analogous to a frontier basin can provide insights into potential unconventional gas resources of the frontier basin . Our method will help industry predict the unconventional hydrocarbon resource potential of frontier basins , guide exploration strategy , infer reservoir characteristics , and make preliminary decisions concerning the best engineering practices as wells are drilled , completed , stimulated and produced .
