3. Overpressure is commonly encountered when drilling in the Caspian Sea. Logmeasurements from a nearby well indicate that the average sediment densitychanges from 2.18 gm/cc to 2.35 g/cc at a depth of 8000 ft below mud line. Logmeasurements also indicate that the thermal gradient is 1.80 °F/100 ft. Thenearby well suffered a blowout and recorded formation pressures of 12,000 psi. Thewater depth at your location is 400 ft and bottom temperature is 17 °C. Your targetdepth is 15,000 ft. Calculate the overburden, pore and effective pressures andtemperature you would expect. Calculate the required safe mud weight (Ibs/gal)to prevent a blowout.
