Perspective Chapter: Drilling Fluid Chemistry – Tracing the Arc from Past to Present

Abstract

This book chapter aims to provide a comprehensive analysis of drilling fluid chemistry and composition and its paramount significance in hydrocarbon exploration. The discussion will meticulously examine various clay types, from conventional bentonite to kaolinite, elucidating their unique contributions to the drilling process. A historical perspective will be employed to trace the evolution of drilling fluids, shedding light on their progression from rudimentary formulations to contemporary sophistication. The orchestrated interplay of density agents, viscosifiers, lubricants, filtrate control agents, and other drilling fluid additives will be explored, highlighting their integral roles in achieving optimal drilling outcomes. Additionally, the chapter will compare drilling fluid additives currently popular in academic research with those in industrial use. This scholarly exploration promises to provide a profound understanding of the intricate chemistry governing subterranean hydrocarbon extraction.
