A well having measured depth, MD = 8847 with a true vertical depth TVD = 6567 ft is drilled with a mud weight of 10.3 ppg. Calculate the dynamic bottom hole pressure (i.e. fluid is circulating) when the the top of the aquifer is 103 ft below the rotary table, and following additional data are given: Drillpipe pressure drop = 0.003 psi/ft, Annular pressure drop = 0.09 psi/ft, pore fluid density = 8.9 ppg
