Part 1: Pore Pressure & Fracture Pressure Estimation

Table 1 shows the average bulk densities for a Miocene in the Tucano Region, Northeast Brazil. Assume an average matrix density of 2.60 g/cm³. The normal pore pressure is 0.452 psi/ft. Table 2 shows the interval-transit times for a prospect in the region. Figure 1 shows the assumed Poisson's ratio for the region.

• Determine an expression for the surface porosity (₀) and the porosity decline coefficient (K_).
• Determine the top of the transition zone.
• Determine the pore pressure curve using the equivalent matrix stress method. The average interval-transit time in the pore fluid is 210 s/ft. Use a margin of 0.8 lb/gal for the pore pressure gradient. Plot the resulting pore pressure gradient versus Depth (put Depth in the vertical axis, pointing downwards).
• Determine the formation fracture pressure curve using Ben Eaton's model (model presented in the course). Obtain Poisson’s ration from the graph in Figure 1 and overburden equal to 1.0 psi/ft on shales. Use a margin of 1.0 lb/gal for the formation fracture pressure gradient. Plot the resulting on the same graph of the item (3).
