Drilling fluid, essential in the construction of oil and gas wells, geotechnical engineering, and other subterranean operations, comprises various properties that determine its effectiveness and compatibility with cement and concrete. Properties such as viscosity, density, pH, and chemical composition play pivotal roles in maintaining borehole stability, cooling and lubricating the drill bit, carrying cuttings to the surface, and preventing fluid invasion into the surrounding formations. The interaction between these drilling fluid properties and cement used for casing and sealing applications is crucial, particularly under the severe environmental conditions found in deep and high-pressure wells.
