INVESTIGATING THE EFFICACY OF NOVEL ORGANOCLAY AS A RHEOLOGICAL ADDITIVE FOR ENHANCING THE PERFORMANCE OF OIL-BASED DRILLING FLUIDS

Investigating the efficacy of novel organoclay as a rheological additive for enhancing the performance of oil-based drilling fluids

Abstract Oil-based drilling fluids (OBDFs) are extensively used in the drilling industry due to their superior performance in challenging drilling conditions.These fluids control wellbore stability, lubricate the drill bit, and transport drill cuttings to the surface.One important component of oil-based drilling fluids is the viscosifier, which pro
