Geophysics Under Stress

Provides an overview of the sensitivity of elastic waves in the earth to the in situ stress, pore pressure, and anisotropy of the rock fabric resulting. With real data examples, this course provides the basis for applying geophysics and rock physics solutions to geomechanical challenges in exploration, drilling, and production.

This is a recording of the 2010 Distinguished Instructor Short Course (DISC) by Colin Sayers. The state of stress within the earth has a profound effect on the propagation of seismic and borehole acoustic waves; this leads to many important applications of elastic waves for solving problems in petroleum geomechanics. This course provides an overview of the sensitivity of elastic waves in the earth to the in situ stress, pore pressure, and anisotropy of the rock fabric resulting from the depositional and stress history of the rock, and introduces some of the applications of this sensitivity. The course will provide the basis for applying geophysics and rock physics solutions to geomechanical challenges in exploration, drilling, and production. Catalog #233A is the accompanying DISC book.
