Overview of Geomechanics and its applications to petroleum industry – a case study for minimum overbalance pressure calculation

Abstract

Geomechanics plays an essential role in drilling and production petroleum industry from beginning with pre-drill well planning and continuing with wellbore stability support while drilling and sand production management. This paper will cover an overview about geomechanics from its fundamental knowledge and geomechanical models to its applications in practical problems of oilfield operations such as wellbore instability, sand production. Additionally, a full review about input data and how to get them by measuring in laboratory and calibration with field measurement will be presented. The result shows that the Mohr – Coulomb criterion can be used for the wells with the borehole inclination from 0 to 60° in this study area.
