  • Patent number: 9047689
    Abstract: A method for visualizing parametric logging data includes interpreting logging data sets, each logging data set corresponding to a distinct value of a progression parameter, calculating a geometric image including a representation of data from each of the logging data sets corresponding to a wellbore measured depth, and displaying the geometric image(s) at a position along a well trajectory corresponding to the wellbore measured depth. The progression parameter includes time, a resistivity measurement depth, differing tool modes that are sampling different volumes of investigation, and/or sampling different physical properties. The geometric images include a number of parallel lines having lengths determined according to the logging data and/or an azimuthal projection of the logging data, a number of concentric axial projections, and/or shapelets determined from parallel lines and/or concentric axial projections.

  • Patent number: 8473212
    Abstract: A method for processing well logging data includes method dividing the well logging data into a number of constant dimensional effect segments, where each constant dimensional effect segment defines an interval having a similar dimensional effect on the log response. The well logging data is taken from a highly deviated well. The method further includes dividing the constant dimensional effect segments into a number of constant property intervals, each constant dimensional effect segment including at least one corresponding constant property interval, and each constant property interval defining a wellbore distance over which a formation property is substantially constant that results in a log response having a low variance. The method further includes providing the constant property intervals to an output device.

  • Publication number: 20120188236
    Abstract: A method includes interpreting first dimensional data such as a caliper log for a wellbore at a first time, and interpreting second dimensional data such as a caliper log for the wellbore at a second time. The method further includes determining a dimensional differential in response to the first dimensional data and the second dimensional data. The dimensional differential includes a volume difference between cross-sectional profiles from the first dimensional data and the second dimensional data. The cross-sectional profiles for comparison may be at a specified axial location or range of axial locations in the wellbore. The method includes graphically displaying the dimensional differential by marking the dimensional differential with a first marker index where the first dimensional data is inside the second dimensional data, and with a second marker index where the first dimensional data is outside the second dimensional data.

  • Publication number: 20100312478
    Abstract: A method for processing well logging data includes method dividing the well logging data into a number of constant dimensional effect segments, where each constant dimensional effect segment defines an interval having a similar dimensional effect on the log response. The well logging data is taken from a highly deviated well, which may include portions deviated at greater than 90-degrees. The method further includes dividing the constant dimensional effect segments into a number of constant property intervals, each constant dimensional effect segment including at least one corresponding constant property interval, and each constant property interval defining a wellbore distance over which a formation property is substantially constant that results in a log response having a low variance. The method further includes providing the constant property intervals to an output device.
