Feasibility Study of Jatropha Based Mud for High Pressure Low Temperature Wells

Growing demand for diesel oil and palm oil by consumers led increased their price in the world market. Increase in price means more expenses for consumers. Industries are mostly depended on diesel oil and palm oil, one of them is Oil and Gas industry, since diesel oil and palm oil widely used in the drilling operation, as the main oil additive for drilling mud This study is aimed to study the feasibility of using Jatropha Oil Based Mud as the alternative, cheap, requiring less chemical additives and environmentally safe drilling mud to replace or to be enough competitive with the current existing drilling mud using other oil additives.
These objectives were achieved by conducting multistage experiments in drilling laboratory. Multimixer, Mud Balance, and Viscometer experimental equipments were used to determine the mud rheology of Jatropha Oil Based Mud and to achieve the study‘s objectives.
From the experiments done, it could be seen that Jatropha Oil Based Mud (JOBM) could indeed be used as alternative drilling mud which requires less chemical additives, cheap and environmentally safe, comparable to the other drilling muds. It is seen that the JOBM requires less chemical additive in order to meet the standard requirements for the drilling mud. JOBM met requirement only by using three main additives: Jatropha oil, Thinner, and Barite Brown (KMC), and managed to exclude the water, Indian Bentonate and other high cost additives.
