摘要： Methods and systems are provided for logging a formation by combining results for a zero-dimensional inversion of conductivity measurements with results for a higher-order inversion of a subset of the conductivity measurement. The higher order inversion can include a 1D-radial portion and a 1D-axial portion. The combined results can include formation characteristics such as Rh, Rv, dip, and azimuth.

摘要： The present disclosure relates to a method to determine a formation property of a subsurface formation. A downhole logging tool having two or more tri-axial antennas is provided and used to obtain azimuthally sensitive data. Borehole correction is performed on the obtained data and a ZD-inversion is performed on the borehole corrected data for all antenna spacing groups. A formation indicator flag is determined and, depending on the determined formation indicator flag, a 1D-axial inversion and/or a 1D-radial inversion is performed over selected zones, or neither is performed. The best ZD-inversion results are selected and the 1D-axial inversion results and/or the 1D-radial inversion results, if any, are combined with the selected best ZD- inversion results to form a composite inversion result. The formation property of the subsurface formation is determined using the composite inversion result.

摘要： A method for determining structural dip of subsurface formations includes accepting as input multiaxial induction measurements made by passing electric current through a multiaxial transmitter disposed in a wellbore drilled through subsurface rock formations. Voltages induced in a multiaxial receiver disposed at a longitudinally spaced apart location along the wellbore are detected while moving the transmitter and receiver along the wellbore. The multiaxial voltage measurements are inverted into values of formation dip magnitude and formation dip azimuth. A parameter related to shale content of the rock formations is measured, and structural dip of the rock formations is determined by selecting dip magnitude and dip azimuth values occurring when the parameter exceeds a selected threshold.

摘要： A method to determine at least one formation property of a subterranean formation includes providing a downhole electromagnetic logging tool having at least one transmitter array and one receiver array and acquiring measurements in the formation using the transmitter and receiver arrays of the downhole electromagnetic logging tool. The method further includes performing a first inversion in response to the measurements, wherein at least one of dip or dip azimuth are assumed constant in an inversion zone within the formation to obtain an inverted formation model that comprises at least one of horizontal resistivity (Rh), vertical resistivity (Rv), dip, and dip azimuth. The method includes determining an n-th order partial derivative matrix of at least one of dip or dip azimuth, wherein n is greater than or equal to 1. The method includes performing a second inversion using the determined n-th order partial derivative matrix, wherein at least one of dip and dip azimuth are allowed to vary in the inversion zone, to obtain an updated formation model. The method includes determining the at least one formation property of the formation using the updated formation model.
