Mathematical Model Correlation Optimizing the Drilling Parameters in Tharjas Oil Field – Sudan

Abstract

Drilling is one of the most complicated and expensive operations in oil exploration and field development. Generally the most problems happened while drilling depends on the formation type; shale/clay formation considered as one of the wildest type causes the instability problems. This study focuses on the physico-chemical mechanical mud properties to get the optimum drilling performance (fewer problems – less cost). Meanwhile, the resulted rate of penetrations using the mathematical model have been plotted to get the optimum weight on bit and rotational speed. This study could be applied over the area using more data for the optimum drilling performance in Tharjas oil field – Sudan
