Subsurface Stress Recognition from Wireline Logs

Bob Cornell, Schlumberger

 
Stresses in the subsurface can be recognized and evaluated from wireline log interpretation. With current interest in highly deviated holes, knowledge of the stress orientation and magnitude is critical to well planning. Well completions, especially fracture design and perforation orientation should also consider subsurface stress regimes. Examples will be shown of induced fractures and breakout, how they are recognized and evaluated. Also to be presented is a map of stress orientation made from FMIs in the Permian Basin and plotted into the World Stress Map project.
