Question

1. While drilling a well, a kick was detected at 10100 ft depth, the driller immediately closed in the well and recorded following data was data:                                                                 

                  Hole diameter                                               = 8 1/2 inch

                  Mud weight                                                   = 13.2 ppg

                  Shut in drill pipe pressure (SIDPP)               = 530 psi

                  Shut in casing pressure (SICP)                    = 800 psi

       Pit gain                                                    =14 bbls

      Assuming that the slow pump rate @30 SPM = 360 psi and the

     Annular pressure loss (APL) = 210 psi determine the Maximum allowable annular surface pressure(MAASP)
