Unformatted text preview: t. Example: Calculate the hydrostatic pressure for 10,000 feet of 12.0 ppg mud. Solution: H.P.=0.052×12.0ppgV10,000ft=6.240psi Copyright(c) 2005 by Ali Ghalambor & Boyun Guo 4 2 A mud gradient can also be used to calculate hydrostatic pressures: Mud Gradient= .052×Mud Weight (p.p.g.) and The hydrostatic pressure=Mud Gradient ×Depth 5 3. Blowout preventers A. Definition The equipment designed to seal the well is called blowout preventers and may consist of either drill pipe blowout preventers designed to control the flow through the drill pipe or annular prevetners designed to control the flow in the annulus. 6 Copyright(c) 2005 by Ali Ghalambor & Boyun Guo 3 B.
