A leakoff test was carried out just below a 13 3/8" casing shoe at 7000 ft. TVD using 9.0 ppg mud. The results of the tests are shown below. What is the maximum allowable mudweight for the 12 1/4" hole section? BBLS PUMPED SURFACE PRESSURE (psi) 1 400 1.5 2 670 880 2.5 1100 3 1350 3.5 1600 1800 1900 4 4.5 5 1920 If the circulating pressure losses in the annulus of the above well is 300 psi when drilling at 7500ft with 9.5ppg mud, what would be the ECD of the mud at 7500ft. If a mudweight of 9.5ppg is required to drill the 12 1/4" hole section of the above well what would the MAASP be when drilling this hole section?
