Drilling mud is a dense, viscous fluid mixture used in oil and gas drilling operations to bring rock cuttings the earth's surface from boreholes as well lubricate cool drill bit. Water-based commonly due its relatively inexpensive easy dispose of. However, several components additives muds become increasingly cautious restricted. Starch was introduced safe biodegradable additive into water-base...

The article provides information on the causes of drilling fluid absorption and research conducted during its absorption. It is known that some complications arise when a well. One them loss circulation. Absorption mainly depends several factors. main factors depend condition well, geological structure correctness processes performed drilling. Also, another factor has an effect, which type flui...

Objective: to analyze the effect of non-toxic components on physical andchemical characteristics drilling fluids. Methodology: determination (density, plastic viscosity, yield point, effective gel strength, water cut, mud cake thickness), chemical (ph). results: threeиdifferent fluids were prepared, their and studied, a Comparative analysis was carried out, impact marine ecosystem assessed. Con...

Recent developments in water-soluble hydrophobically associating polymers are examined with particular emphasis on their use for oilfield applications. These polymers have potential for use in EOR, acidizing, drilling fluids, completion fluids and profile modification. They have also been reported to selectively reduce water permeability in sandstones, and have been used as drag-reducing agents...
