The science of geomechanics – the evaluation of the interplay between stress, pressure, mechanical properties and strength in rock and soil – has become a critical, go-to technology in the characterization and engineering of Unconventionals Plays. But why the fuss? Why has geomechanics, which has its roots in the development of tunneling technology in the 19th century, become so important in the optimization of Unconventionals? Equally important, how is the non-expert supposed to make sense of the confusion, gaps, and controversial opinions on the application of geomechanics to Unconventionals?
The short course will cover the geomechanical considerations for unconventional developments with a focus on its critical role in formation characterization and completion optimization. Unquestionably, geomechanics does play a critical role in the understanding and development of many unconventional reservoirs – chiefly due to the complicated and variable geomechanical impact of natural fractures and weakness planes in completions and drilling. Within the short course, we will introduce unconventional developments and their characteristics. Following this, the nature and geomechanical behavior of natural fractures and weakness planes will be reviewed. With this foundation, the role of microseismic monitoring – as it portrays rock failure – will be presented. The course will then conclude with an extensive review (based upon stress, pressure, and mechanical property fundamentals) of common geomechanical issues (i.e., brittleness, complexity, stimulated rock volume - SRV) in the characterization and engineering optimization (i.e., stage spacing, landing location, etc.) of Unconventionals.
