More Information
Summary:A method of estimating a petrophysical property of a subsurface area that includes deriving an acoustic calibration relationship correlating acoustic propagation characteristics of a first subsurface area with a petrophysical property of the first subsurface area determined using nuclear spectroscopy measurements; processing acoustic data acquired from a second subsurface area to determine acoustic propagation characteristics associated with a plurality of regions within the second subsurface area; and estimating the petrophysical property of the regions within the second subsurface area using the calibration relationship and the acoustic propagation characteristics associated with the second subsurface area. An associated method includes determining one or more boundaries within the first subsurface area, deriving different acoustic calibration relationships on opposite sides of these one or more boundaries, and then using these different acoustic calibration relationships to estimate a petrophysical property of regions within the second subsurface area.
