  • Machine method for determining the presence and location of hydrocarbon deposits within a subsurface earth formation
    Patent number: 4502121
    Abstract: In accordance with illustrative embodiments of the present invention, methods for processing well logging data comprises deriving measurements of a plurality of earth formations parameters and combining these measurements in a new manner to enable interpretation of shales and shaly sand type formations. More particularly, measurements of a plurality of the hydrogen index, bulk density, radially deep and shallow resistivity, spontaneous potential, acoustic travel time and natural formation radioactivity content are made and combined in a manner to produce data useful in evaluating shales and shaly sand type formations.
    Type: Grant
    Filed: March 12, 1979
    Date of Patent: February 26, 1985
    Assignee: Schlumberger Technology Corporation
    Inventors: Christian M. Clavier, Jean L. Dumanoir, Alexis C. Dumestre
