Geologic Factors Associated With Successful Shale Gas Plays
Shale is the most common sedimentary rock-type in the world, and massive shale deposits can be found on every continent. A lithologic unit is classified as shale if it is composed of finegrained sediments. To determine if a particular shale is viable as an unconventional hydrocarbon play, various geologic factors must be understood about those sediments. As an example, the shale’s mineralogy must have certain characteristics that will allow it to be fractured. The recent shale revolution also required the development of innovative drilling and completion technologies to transform a shale that previously acted as an impermeable seal or barrier for conventional hydrocarbon traps into a producible reservoir. This presentation outlines the key geologic factors required to have a successful shale gas play. It also highlights the fact that all shales are different, and understanding those differences is key to successful shale exploration.
