Study on the Filtration Properties of the Drilling Mud Mixed with Synthetic Rubber Latex

Abstract
Styrene-butadiene latex (SBL) is a polymer emulsion that can be used to increase the filter loss control, gel strength, coating, viscosity, and good adhesion and elasticity property of drilling mud. The objective of this research is to study the effect of SBL proportion and temperature for improving the filtration properties of drilling mud. The drilling mud was mixed with 0.3, 0.5, 0.7 and 1 percent of weight by volume of SBL under ambiance condition at 30, 60 and 80°C base on the API RP13B-1 standard. The result offiltration properties test indicated that API fluid loss values of SBL mixed with drilling mud are better than base bentonite mud about 20 percent improvement.
