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.

Which is the most popular drilling polymer for oilfield industry?

PARTIALLY HYDROLYSED POLYARYLAMIDE (PHPA) manufactured by GDFCL at its ISO Certified manufacturing Facility in Gujarat, one of the most Popular Drilling Polymers for the Oilfield Industry PHPA is a co-polymer of anionic character and high molecular weight.

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.

Which drilling fluid is compatible with PHPA?

It is compatible with most of the drilling fluid products, biopolymers, PAC, CMC. It maintains borehole stability by preventing shale swelling and erosion. PHPA maintains viscosity in solid free drilling fluid. As a Bentonite extender in low solids non-dispersed mud, it can be used along with small addition of Bentonite to suspend weight material.

Are nanocomposites a drilling fluid additive?

Hence, nanocomposites have got wide attention as drilling fluid additive for various purposes. Nanoclays are nanoparticles of layered mineral silicates. These are categorized into several classes like montmorillonite, bentonite, kaolinite, hectorite, and halloysite based on their chemical composition and nanoparticle morphology.

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).
