DE0967 : Wellbore Stability & Geomechanics

Course Description

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. This course is designed to examine the complexity of wellbore stability/drillability analysis in drilling operations with a view to optimizing well planning, construction and post evaluation procedures. Geomechanical models developed from data acquired during previous drilling operations along with log and seismic information will be introduced. Application of real time well bore stability management system through monitoring of surface and down hole drilling parameters, cuttings inspection, drilling fluids and log data analysis provide necessary tools to prevent avoidable instability issues. It is hoped that by combining drilling logs, offset well data and drilling technologies driven by a proper understanding by participants of the geomechanical profile of prospects, future wells will be successfully constructed in terms of cost savings and minimizing time overruns on drilling projects. The course discusses the fundamental theories that are critical in current well designs and well instability problems. It looks at the issues of rock properties, subsurface stresses and methods for the prediction of rock behaviour under varying operational conditions. The impact of rock and well instability on well economics is emphasized. Well bore instability has continued to be a major cause of non productive time and cost over runs in several fields while drilling, causing delays and well suspension before reaching drilling targets.
