Compute the solution of the given question0
Question- In a sedimentary basin, the lithostatic gradient is 1 psi/ft and hydrostatic gradients is 0.454 psi/ft.
Part 1- Calculate the lithostatic stress and hydrostatic pressure at the depth of 1 km and 4km, respectively, assuming the pressure at the surface is 0.
Part 2- If the measured reservoir pressure at this depth is 90 MPa, is the reservoir over-pressured? (1 MPa = 145 psi; assume that the Biot parameter is 1)
I need experts help to find the lithostatic stress and hydrostatic pressure.
