Скачать или смотреть Pressure and Temperature Effects on Density in OBM, SBM & WBM

Drilling fluids show significant density dependence on both temperature and pressure. As temperature increases with depth, liquids expand and subsequently increase in volume, but its mass does not change; thus density decreases with temperature. The opposite is found relative to pressure increases, OBM compresses and subsequently decrease in volume, but its mass does not change; thus density increases with pressure.
