  • Pore Pressure an overview ScienceDirect Topics

    Pore pressure prediction in claystone/shales is based on the premise that the response of sonic velocity, resistivity, and density tools are a proxy for porosity. A further assumption is that high porosity in the formations at depth is due to the inability to dewater (compact with depth). The retention of water a) preserves porosity and b) requires that the retained
