INVESTIGATING THE VIABILITY OF LOCAL VEGETABLE OIL AS BASE FLUID FOR DRILLING HPHT FORMATION

The aim of this study is to investigate the properties of local vegetable oil and look into the possibility of using this fluid in the real drilling operation in high pressure and temperature by extracting the real drilling fluids with a long series of experiments in order to get their properties and compare to local vegetable fluids to meet standard requirement and select the best among candidates to use as base drilling fluid as answering the technical performance and sustainable development.
The scope of this study will focus deeply on the rheological properties of the available local vegetable oil through this semester. However, it will be shared some part of the research to the co-worker to achieve the optimum result.
Vegetable oil in this project – Coconut oil are renewable, highly biodegradable could be suitable candidate of a highly biodegradable oil-based mud to achieve the sustainable development. Thus, six mud samples were formulated with six different composition of base fluids which are Saraline, 100%, 80%, 70%, 60%, 50% Coconut oil based mud samples.
The results that obtained from this experiment will compared to the standard oil based mud in the drilling operation in high pressure and high temperature. The best among candidate will further research to replace diesel oil in the future.
This research will be the answer both technical performance and environmental concern when the selected oil sample will be extracted properties during the experiment. The sample will undergo the process to meet the standard requirement of oil based mud. Owing to The environmental concern will be reduced when there is no pollution to the marine environment, moreover, it will bring value to the local vegetable oil to the oil and gas industry. And this is how the research bridges the gap between both of them to reach real sustainable development in the future.
