Mud hydrostatic head
Web26 iun. 2015 · To show a somewhat more complicated static pressure solution, consider the density equation for an ideal gas: where T is absolute temperature, and R is a constant. For an ideal gas, density has an explicit dependence on pressure and temperature. The solution to Eq. 2 for a well with constant slope Φ is. Webgradient for both seawater and mud that originates at the sea surface (Schubert, et al., 1999). Because dual gradient drilling has much less hydrostatic “head” associated with the drilling mud in the borehole, drilling fluids can be properly weighted, allowing drilling to be more easily Figure 2.
