1. While drilling at 9000 with 10.0ppg mud, complete loss of circulation was encountered. Fluid D: Solve the following problem level was found at 500ft below rotary Kelly bushing. Determine the maximum formation pressure. At the moment of losses friction pressure drop was 200 psi. What is the maximum mud weight to be circulated without changing pumping rate, assume the same annular pressure losses
