  • Publication number: 20200326455
    Abstract: Systems and methods for determining a numerical age for new geological events within a new scheme by ordering relations between geological events within a new scheme and/or within a new scheme and a preexisting scheme into a preferred hierarchy, dynamically excluding lower relations in the preferred hierarchy that conflict with higher relations due to irreconcilable ages of the relations, and using the ordered relations remaining in the preferred hierarchy to determine a numerical age for the new geological events within the new scheme.

  • Patent number: 10669845
    Abstract: Tubular stretch correction for different operational conditions is applied to determine tubular wear volume. The tubular stretch correction is applied as a function of a stretch factor comprising a varying shift factor, axial load on the tubular string, pressure effects on the tubular string, buckling of the tubular string and/or temperature effects on the tubular string. Stretch factors are taken into account to determine the correct position of wear factors along the casing string, which are ultimately used to determine the casing wear volume.
