1) Knowing the pore pressure in a formation in advance is essential for planning a drilling program. Your company is planning an exploration well at location W in the sketch below, and you have obtained the depth and average pore pressure encountered in the Basenji formation from six other wells in the region. a. Estimate the depth at which you will encounter the Basenji formation when you drill at location W . Explain whether your estimate is data driven or model driven. b. Estimate the pore pressure of this formation at location W . Explain whether your estimate is data driven or model driven. 4250 ft 1750 psia 41 00 ft 1750 psia 3610 ft 1500 psia 38 80 ft 1600 psia 4300 ft 1850 psia 3500 ft 1450 psia W 10 points
