Drilling-fluid densities vary significantly over wide ranges of temperatureand pressure, a concern that is particularly critical in deepwater, Arctic, andhigh-pressure/high-temperature. The variations can affect well integrity, welldesign, regulatory compliance, and drilling efficiency. Drilling-fluiddensities depend on the compressibility and thermal expansion of the fluids(liquids) and solids used in their formulation. Suitablepressure/volume/temperature (PVT) correlations for these fluids previously havebeen fairly inaccessible, primarily because of continually changing base fluidsand blends, and the lack of readily available test equipment. This study wasconducted to measure the volumetric behavior under extreme temperatures andpressures of a broad range of the oils, synthetics, and brines currently usedin industry to prepare oil-, synthetic-, and water-based drilling fluids. Itfollows a recent study that successfully qualified the commercially availabletest equipment. For the most part, tests for this study were run attemperatures from 36 to 600°F and pressures from atmospheric to 30,000 psi,ranges that generally exceed those provided in other published studies.Correlation coefficients are provided for reference and to demonstrate theiruse in a compositional, material-balance model to accurately predictdrilling-fluid density as a function of temperature and pressure. Tests run onfield drilling fluids are included to demonstrate how these data can be used inprocedures and software to predict equivalent static density and hydrostaticpressure during drilling operations.
