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.

What are BASF drilling fluid additives?

BASF drilling fluid additives are high-performance, temperature-stable and contamination-tolerant products for a variety of drilling fluid systems. The descriptions, designs, data and information contained herein are presented in good faith, and are based on BASF’s current knowledge and experience.

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.

What is polydrill®?

Polydrill® is a fluid loss additive and the flagship of our broad range of products for drilling muds. The product is characterized by a unique combination of properties. As a fluid loss polymer, it is temperature stable to more than 200 °C / 400 °F. This qualifies Polydrill® for use in the deepest wells currently being drilled.

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).

Does nanocomposite concentration affect drilling fluid loss volume?

The fluid loss volume of the drilling fluid formulations was in the acceptable range (9.8–2.8 ml) at concentration of 0.4–0.8% nanocomposite (Kosynkin et al., 2012, Khodja et al., 2010). The fluid loss volume was decreased further with the increase in nanocomposite concentration (2.8 ml).
