Building geomechanical models - PetroWiki


This section outlines methods for determination of the stress magnitudes and the pore pressure. Overburden pressure, or Sv, is almost always equal to the weight of overlying fluids and rock. Thus, it can be calculated by integrating the density of the materials overlying the depth of interest (see Figure 1). Figure 1--(a) Density logs for a subsea well beneath 1,000 ft of water, extrapolated to the mud line using an exponential curve. Density within the water column is 1.04 gm/cm[1].
