Sustainable aspects behind nano-biodegradable drilling fluids: A critical review

Drilling fluid is used in the drilling of oil and gas wells as an essential part of the operation. In recent years, there has been increased interest in the use of nano and biodegradable materials in drilling fluid to combat variety of challenges. Several researchers investigated the impact of different nano and biodegradable materials ranging from commercial to custom-made particles to develop drilling fluids with increased characteristics that can endure harsh downhole conditions especially under high pressure and high temperature conditions. The purpose of this work is to analyze the results of these researches and the improvements that were noticed from the application of the novel materials in drilling fluids. This paper offers the investigators with a complete summary, comparison of current advancements in the field of drilling fluids and identify the suitable novel materials that can increase the oil and gas industry's competitiveness. It was noticed that the rice husk and pomegranate peel powders as biodegradable materials improved the rheological and filtration properties significantly. In addition, the nano-clay and titanium oxide have a significant impact on the properties of the drilling fluid. Thus, a combination of these novel materials (titanium and pomegranate peel) can improve these properties along with providing the wellbore stability.
