  • Method for determining pore pressure and horizontal effective stress from overburden and effective vertical stresses
    Patent number: 4981037
    Abstract: The porosity-effective stress relationship, which is a fuction of lithology, is used to calculate total overburden stress, vertical effective stress, horizontal effective stress and pore pressure using well log data. The log data can be either real time data derived from measurement-while-drilling equipment or open hole wireline logging equipment.
