This report basically discusses the preliminary research done and basic understanding of the chosen topic, which is Properties and Utilization of Jatropha Curcas Oil for formation Damage Control. Jatropha seed is the seed from the jatropha trees. The seeds from this tree will be used as a research product. Jatropha trees canbe easily plant at the khalatulistiwa area. The trees are very easy to plant and its have very strong physical properties. The oil from jatropha seeds can be produced by two ways: mechanical pressing and chemical extraction. In general there two types of products from jatropha oil: as cosmetic and biodiesel. For biodiesel, there are a lot of researches on producing the biodiesel Then, this research basically is about to expand the used of thejatropha oil as a part of drilling fluid in the oil and gas industry. The oil will be used as an oil base mud for drilling. Nowadays the type of oil that used as an oil base mud in drilling is diesel and palm oil and of course these two types of oil are very high demand in the market. Formation damage is an undesirable operational that frequently happened during drilling activities. The damage of the formation will reduce the permeability and the porosity ofthe core to transfer the crude oil from wellbore to the well. The damage may cause by several factors including chemical, physical, biological and thermal interactions of formation and fluids, and deformation of formation under stress and fluid shear. For the physical mechanism of formation damage clay swelling, fines migration, solid invasion and geochemical transformation will be the major factor of formation damage. For the chemical part the type ofmud will bea major cause ofthis phenomena. Then, it is important for the mud engineer to determine the right composition ofthe mud that used as a drilling fluid. The objective of the project is to determine the properties of the jatropha curcas fruit in order to apply it to substitute the surfactant that used nowadays in the reservoir by determine the rheology of the mud using the drilling lab equipment such as mud balance to determine the density of the mud and the viscometer to determine the other important parameter like Yield Point and Plastic Viscosity. The standard for all this parameter will refer to the API standard. The research will also investigate the reduction of formation damage by this mud using FDS-800-10000 equipment at UTP drilling lab. The parameter that involve in this activities will be the change of the permeability and porosity ofthe core. The condition oftemperature and the pressure will be set equally as in the reservoir before the experiment being applied. The hypothesis for this research is theoil can beused aspart ofthe oilbase mud in during drilling activities.
