Determine the pore pressure curve using the equivalent matrix stress method. The average interval-transit time in the pore fluid is 210 µs/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).
