The invention of latest and modern technology has leads to the deep water drilling. Deep water drilling required good performance drilling fluid that can withstand high temperature and pressure, therefore oil based-mud (OWB) is preferable in the drilling fluid selections. The purpose of this study is to evaluate the performance of Saraline, Sarapar, and Diesel individually as base oil in High temperature High Pressure (HTHP) condition, based on the fluid loss and the changes of their rheological properties before and after ageing time. A portable HTHP filter press was also used to study the filtrate-loss at pressure of 500 psi and temperatures of 250 oF. This experiment showed that, the rheological properties of Sarapar gave better performance compared to Saraline and Diesel, therefore it is the most suitable based oil to be used in formulating drilling fluid for deep water drilling.
