Abstract
Sometimes when drilling is in progress, we have to deal with high pressure and high temperature. It happens specially when the target is deep enough or geothermal well. HPHT condition will be able effect the performance of drilling fluids by altering its rheological at high pressure up to 3000 psig and high temperature up to 200oC by Farm Model 70. Research was done with various additive, such as Chemtrol-X, CMC LV, Polyplus and Ligco, with have objective to repair mud rheological at HPHT. Based on this research by API recommended on pound per barrel (ppb). Results of this research are die composition is 2-3 ppb additive to be added on water based mud and stable rheology up to 200 °C.1. INTRODUCTIONDrilling operation problems such as abnormal pressure, swelling and high temperature condition usually found during drilling progress. Drilling mud characteristic and rheological properties will be effected by high temperature effect. With increasing temperature of drilling fluids, viscosity will decreasing, this condition will make cuttings or chips are not effective carried and sludge will be occurs at base hole bore (pipe sticking). The solution for this problem is to add additional additives which resistant to High pressure and high temperature (HPHT) condition.The purpose of this research is to search additives stabilities by altering its rheological characteristic in HPHT condition. This research used fresh water mud (Wyoming Bentonite) and HPHT Viscometer Farm Model-70 to measure the rheologi of drilling fluids. This research will be studied the rheological properties of drilling mud and additional resistant additives in based drilling mud with variation of additive concentrate and variation of experiment temperature. The best combination of additives from base mud at certain HPHT will be obtained from the result of this research
