Fluid loss controller improves the fluid retention capacity of drilling fluid during the oil and gas drilling process. Cetyltrimethylammoniumbromide modified polyacrylamide acts as a rheology modifier and fluid loss controller at very low concentration of 0.2 %(w/v) in water-based mud. The performance of polyacrylamide complex in the Na-montmorillonite fluid was analysed by using it in powder and gel form. The dispersed drilling fluid was formulated using pre-hydrated montmorillonite chrome free lignosulphonate and Na2SO3. Experimental results show that polyacrylamide complex provides Enhanced fluid loss control and excellent shear thinning rheology property to the fluid. Performance efficiency of polyacrylamide complex is studied in non-weighted and weighted fluid system. The bridging efficiency of polyacrylamide complex in the fluid was confirmed by analysing fluid cake in scanning electron microscope and energy dispersive X-ray spectroscopy.
