Impact of Natural Polymer (Xanthan Gum) and Bentonite Clay on the Development of Oil-In-Water (O/W) Emulsion Drilling Fluids

Drilling fluid plays the same role in oil and gas well drilling as blood human body. A new type of oil-in-water (o/w) emulsion has been developed using diesel dispersed phase, brine water continuous xanthan gum viscosity modifier clay stabilizer filtration controlling agent. Initially, standard recommended techniques were opted to detect rheological properties emulsions. The fluids have also shown stable upto 70°C after aging for 24 h. As encounter a lot variation temperature pressure depth increases, hence stability such becomes an imperative parameter. Furthermore, itself is heterogeneous fragile system so was investigated shear stress-shear rate rheology measurements. Emulsions strong shear-thinning (pseudoplastic) behaviour which considered advantageous property fluids. Experiments conducted determine dynamic emulsions elastic towards breakdown processes. physical 30 days at ambient conditions. Inter-facial variables zaeta potential, inter-racial tension (IFT) contact angle measurements examine their characterization.
