FEASffiiLITY STUDY OF JATROPHA BASED MUD FOR IDGH 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.
