Can polyacrylamide/clay nanocomposite be used as drilling fluid additive?

The troublesome shale formations need special formulation of drilling fluids having high shale inhibition characteristics to mitigate wellbore instability problems. In the present study, polyacrylamide/clay nanocomposite (PANC) was synthesized and used as drilling fluid additive.

How are salt polymer drilling fluids selected?

The drilling fluid properties are investigated to determine the performance levels required. Additives are compared against the models. The economics of the various products are then evaluated to select the optimum fluid for the well. The salt polymer drilling fluids systems follow the same basic makeup.

What is poly aluminum chloride?

Poly Aluminium Chloride (PAC) is a highly efficient coagulant with the chemical formula [Al2(OH)nCl6-n]. It is widely used in water treatment processes to remove suspended solids, organic matter, and other contaminants.

What is poly Aluminium chloride (PAC)?

Poly Aluminium Chloride (PAC) is a highly efficient coagulant with the chemical formula [Al2(OH)nCl6-n]. It is widely used in water treatment processes to remove suspended solids, organic matter, and other contaminants. PAC is available in both liquid and powder forms and is known for its ability to perform effectively over a wide pH range.

How does poly Aluminium chloride work?

It works by destabilising and aggregating particles, making it easier to remove them through sedimentation or filtration. Poly Aluminium Chloride is preferred in many water treatment applications due to its quick reaction time, reduced sludge production, and the ability to operate efficiently in cold temperatures.

Which nanocomposite is used for water based drilling fluid system?

The various grades of the nanocomposite prepared with various clay to monomer ratios (0.05–0.25) during the synthesis of the nanocomposite were used for the development of the water based drilling fluid system. The effect of clay loading during the synthesis is shown on the rheological and filtration properties of the base fluid system (Fig. 5).
