摘要： 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. The method further includes determining constant property intervals in 3D volume space projected them into true stratigraphic thickness, and providing the resulting log-squared data to the output device.

摘要： 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. The method includes dynamically determining a selected measured depth, measured depth interval, and/or azimuthal projection angle.

摘要： 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.

摘要： A method for determining permeability of a subsurface formation includes measuring a parameter related to fluid content of the formation at a first time from within a wellbore penetrating the formation. A rate of entry of fluid from the wellbore into the formation is determined from the measurement of the parameter made at the first time. The permeability is determined from the rate of entry.

摘要： In drilling a well, a condition at the surface which contributes to a downhole condition is identified. A set of observed measurements is collected for the surface and downhole conditions. From this set of observations a predictor equation is derived which expresses the downhole condition as a function of the measured surface condition. After the predictor equation has been developed, it is applied to a measured surface condition to estimate the resulting downhole condition.
