Solubility of methane in synthetic mud
WebApr 1, 2024 · Accurate prediction of CH4 solubility in oil-based mud is significant for evaluating gas kick severity and implementing proper well control. The main factors affecting gas solubility in oil-based drilling fluid are base oil content, pressure, temperature, drilling fluid viscosity, and the components in natural gas. This work tests the complete … WebSuch a large solubility will cause a significant impact on the annulus transient flow. The influences of temperature and pressure on methane solubility are similar to those in water-based mud. Methane solubility in oil-based mud increases with pressure, and the higher the pressure, the greater is the solubility increment.
