- Abstract
One of the problems that is very avoided when oil and gas drilling operations is the filtration loss. The usual and often used additive to overcome this problem is the Carboxymethil Cellulose (CMC) where the CMC is relatively expensive, so research needs to be done using alternative materials or natural ingredients to make it more economical. The alternative material used in this study was corn starch because of its polymer composition and its function fluid loss control and viscosifier. This study was conducted to determine the effect of starch on filtration loss and rheological drilling mud by determining the filtrate volume, mud cake thickness, viscosity, plastic viscosity, gel strength. Corn starch is made by smoothing and filtering corn with gauze, after that it is dried in the sun to dry and do sieve analysis with a size of 200 mesh. Then corn starch with a composition of 2, 4, 6, 8 and 10 grams mixed with standard mud. Filtration loss testing is done using an Low Pressure Low Temperature (LPLT). Rheological tests such as viscosity use marsh funnel devices while plastic viscosity and gel strength use the Fann VG Meter tool. The results showed that the filtration loss obtained was 14,7 – 12,7 ml, mud cake thickness of 1,5 – 1,1 mm, viscosity of 42,38 – 60,02 cp, plastic viscosity of 4 - 11 cp, gel strength of 0,2 – 0,54 (lb / 100 ft2). Mass addition which will reduce filtration loss and mud cake and vice versa with the addition of mass causes increased values of viscosity, plastic viscosity and gel strength.
