APPLICATION OF SPECIFIC ENERGY FOR BIT SELECTION HASSI-MESSAOUD OMG-501

Abstract

This thesis examines the application of mechanical specific energy optimisation techniques in cost reduction through prediction of optimum ROP using real-time drilling parameters data and intrinsic formation data acquired during the actual drilling process, also how drill bits could be chosen. In fields where offset well data exist accurate field penetration rate benchmark can be established aiding cost optimisation. In recent times, the number of wells drilled in HMD has risen with the oil price, however growth is patchy and the actual spending on wells is rising rapidly. Spending surge on drilling cost impacts on the bottom-line performance and sustainability of E&P business. Therefore, the need for drilling performance improvement as operational cost reduction initiatives has become a critical industry goal.
