  • Method and apparatus for generation of 3D graphical borehole analysis
    Patent number: 6078867
    Abstract: A system and method is disclosed for generating an oriented three-dimensional graphical representation of a borehole. A system is implemented for receiving oriented caliper and borehole trajectory data taken by a 4-arm (or more) caliper device relating to a borehole. This information is used to generate an oriented three-dimensional wire mesh model of the borehole and color map the generated three-dimensional wire mesh model using the caliper data and gamma ray (or other lithology indicator) to reflect one or both of the orientation of borehole ellipticity or the lithology of the borehole.
