COMPARISON ON THE FILTRATION PROPERTIES OF THE DRILLING MUD CONTAINING SYNTHETIC LATEX AND COMMERCIAL ADDITIVE
Keywords:
SBL, Carboxymethyl cellulose, Xanthan gum, API fluid lossI, Lost circulation additiveAbstract
The objectives of this research were to study (1) the physical properties of drilling mud with Styrene-butadiene latex (SBL) as an additive, (2) the effect of SBL proportion and temperature for improving the filtration properties of drilling mud, and (3) compared the filtration properties and cost of drilling mud mixed with SBL, Xanthan gum, and Carboxymethyl cellulose (CMC). The research identified the effect on the rheological and filtration properties of the drilling mud mixed with 0.3, 0.5, 0.7, and 1 percent of weight by volume of SBL, Xanthan Gum, and CMC under ambiance condition at 30, 60, and 80C, respectively. Physical properties of the mixed drilling mud included viscosity, gel strength, and filtration were investigated according to the API RP 13B-1 standard. The results of filtration properties test indicated that API fluid loss values of SBL, Xanthan gum, and CMC mixed with drilling mud were better than base bentonite mud about 20, 65, and 68% improvement, respectively.
