Geomechanics of Unconventional Reservoirs

Virtual, May 3 & 4, 2021

 

The course will be virtual and held in English with simultaneous translation to Spanish, and a duration of 14 hours.

 

Course description

 

Geomechanics – in both completion and drilling operations – has become a critical technology in the development of Unconventional Reservoirs. This course presents the application of the basics of oil field geomechanics to unconventional developments; specifically, the role of stress, pore pressure, mechanical properties, and natural fractures on hydraulic fracturing operations. The first portion of the course will focus on the importance of oil field geomechanics, geomechanical modeling and workflows as a necessary part of reservoir characterization for Unconventionals. The second part of the course will focus on the geomechanics of hydraulic fracturing for Unconventionals with an emphasis on proper characterization, modeling, interpretation and field aspects (i.e., hydraulic fracturing in heterogeneous rock masses with the presence of discontinuities and weakness planes). At the end of the course, it is expected that attendees will be able to specify and QC a geomechanics evaluation program for Unconventionals, and understand the key geomechanical issues and inputs for hydraulic fracture optimization in Unconventionals.

 

Who Should Attend

 

The course approaches geomechanics from an engineering aspect of completion optimization in Unconventionals. The course is intended for geoscientists, reservoir, drilling, and completion engineers, and students with background in geomechanics who are engaged or are interested in the development of Unconventionals.
