This report basically discusses the overall element of the project which is entitled, Optimization of the Feldspar Usage in High Temperature Drilling Fluid. This research will be a stepping stone for future research of the new potential drilling fluid additives which is obtained from abundant local resources. The objectives of the project are to discover the properties and characteristics of quartzo-feldspathic rock, to discover the effect of feldspar addition on the drilling fluid properties and to determine the effect of formulated drilling fluid in high temperature and high pressure well condition. In order to correlate cost and effectiveness of the additive, the natural sources of additive (feldspar) which found abundant in Malaysia is determined its potential. In drilling process, drilling fluid could alter in situ formation. In the operation main problem with drilling fluids and additives are concerned on the effect of the drilling fluid log interpretation and on cuttings analysis. Minimizing the environmental impact of a drilling operation as well as safety considerations both directly affect the choice of drilling fluid additives and drilling fluid systems. The methodology of the project is kept with relevancy of current technology. The rock properties identification are using SEM and XRD. Meanwhile, the drilling fluid properties are identified using viscometer, HPHT viscometer and HPHT filter press. The project met its objective, and as a result, feldspar could be used as a loss circulation material additive as it shows a good result in filtration test.
