Structural Implications of Pore Pressure

Abstract

Abnormal fluid pressures have already been defined by the statement on normal fluid pressures in section 1.5 (1.5/3). Fluid pressures leading to an overall pressure gradient in the range of 0.43 to 0.48 psi/ft (0.0097 to 0.0109 MPa/m) have been termed normal. This range is accepted in view of the variable density of formation waters AND the limited accuracy of pressure measurements which in the best of cases is within one per cent of range, but often is not more than a close guess based on mud weights or surface pressures, occasionally measured with partially open flow lines.
