Geophysical Methods for Estimating Geomechanical Properties, taught by Steve Adcock, is designed for geoscientists, engineers, and managers who wish to understand the application of geophysical methods to geomechanical challenges. A geosciences or engineering degree, or work equivalency is recommended. This course will take place February 13 – 14, 2014 in Houston, and is a part of the Winter Education Conference.

Participants attending this course will gain an understanding of:
–different geophysical methods and techniques for determining geomechanical properties.
–workflows for determining and using geomechanical properties for drilling and reservoir management.
–when and why geophysical methods should be applied to their reservoir characterization and geomechanical modeling workflows.
–how these methods and techniques could be applied to their own challenges.
This course is an overview of geophysical methods and techniques for estimating geomechanical properties. It is intended for intermediate geoscientists and engineers who will gain from the course an understanding of how and when geophysical methods can best be used to answer questions about geomechanics and reservoir characterization. A review of methods from principals to estimation of geomechanical parameters will enable participants to better focus their geophysical resources upon returning to work. The course will also provide more experienced geoscientists with an understanding of methods and techniques which can be introduced into their workflows to help resolve geomechanical drilling and production challenges.
Geophysical technology and data types known to support geomechanical modeling and reservoir characterization will be presented on the first day. Beginning with gravity and magnetics, which can be tools for estimating regional tectonics and stress, the course then moves to surface electrical and seismic methods, where the most common techniques, acoustic and elastic inversion, are discussed. Correlation of seismic with logs and rocks is followed by an examination of the role of VSPs, 3D, and 4D seismic.
Day two starts by combining regional information and 2D seismic into seismic sequence stratigraphic frameworks for basin and petroleum systems analyses. These analyses are the foundation for workflows to evaluate conventional and tight petroleum reservoirs and provide boundary conditions for modeling parameters. The course then focuses on faults and fractures, which enforce compartmentalization and directionality on drilling, perforation, and hydraulic fracturing. Interacting with reservoirs and data acquisition at all scales, faults and fractures must be carefully incorporated into interpretation, modeling, and operational workflows. From this, the course moves on to an example of petroleum resource development: the discovery and early development of the Barnett Shale, mother of hydraulic fracture plays. This is followed by a more in-depth look at geomechanical modeling. The course closes with a review of new technologies and methods involving geomechanics which have been presented over the past year at technical workshops, forums and conventions.
