Abstract

This project concerns on the investigation of the effect of banana trunk derive from plant waste as a lost circulation material in water-based drilling fluid. The objectives ofthis project are to determine the effect of banana trunk on density and rheological properties of drilling fluid, to compare the change in properties of drilling fluid between banana trunk, corn cobs and sugar cane and also to determine the suitable particle size of banana trunk between 63um and 125um as a lost circulation material in water-based drilling fluid for respective selected core sample through formation damage system test. For this project, water-based drilling fluid is used. The loss of drilling fluid is usually more costly for oil-based fluids because the base fluid is more expensive but the loss of fluid can be quite costly with water-based fluid because of the chemicals in the fluid. Banana trunk which contains a flattened, modified stem called pseudostem consisting layers ofleafsheath and crown oflarge leave contain of fibers which is potential to use as a loss circulation material. Tests have been conducted in accordance with the by API RP 13B-1 procedure and the related equipments used are mixer, mud balance, viscometer and formation damage system device. Properties measured through this experiment are density, plastic viscosity, yield point, 10 seconds and 10 minutes gel strength, pH and permeability for formation damage test. The pesudostem will undergo drying, dehumidifying, grinding and sieving process. The blend of pseudostem added in drilling fluid will be large enough to form bridge of material in the fracture or cavern formation. The results show thatthe rheological properties of drilling fluid increase in value as the amount of banana trunk added increase. Through formation damage system test, it shows that 63umparticle size of banana trunk was efficiently act as lost circulation material for this core sample as compared to 125um particle size.
