Paper presented at the 49th U.S. Rock Mechanics/Geomechanics Symposium, June 28–July 1, 2015
Paper Number: ARMA-2015-212
... estimate the osmotic pressure resulting from an imbalance of water activities—in effect, estimating a higher mud weight needed to stabilize the well. This methodology was applied to a well drilled in the North Sea combined with mechanical wellbore-stability analysis and shows good agreement with wellbore...

Paper presented at the 49th U.S. Rock Mechanics/Geomechanics Symposium, June 28–July 1, 2015
Paper Number: ARMA-2015-331
... Abstract Nine meters of shale core have been cut from the upper part of the Upper Jurassic Draupne Formation within the Ling Depression in the central part of the North Sea. The main objective was to provide high quality core for rock mechanical and geophysical studies related to seal...

Paper presented at the 48th U.S. Rock Mechanics/Geomechanics Symposium, June 1–4, 2014
Paper Number: ARMA-2014-7169
... Abstract We calculate the effective vertical and horizontal stresses in the Hejre field, North Sea with a Biot’s coefficient estimated from log data. We show that a drilling window (for a vertical well) calculated with these stresses is larger than if using a Biot’s coefficient of 1. We show...
