  • Publication number: 20210041594
    Abstract: A transmitter of a downhole tool inserted in a borehole of a geological formation transmits a first signal. A receiver of the downhole tool receives a second signal, where the second signal is induced by the first signal in the geological formation. A simple response matrix is determined based on the second signal, where the simple response matrix includes a plurality of response components. One or more of the response components are combined and a modified response matrix is formed by replacing one or more of the plurality of response components in the simple response matrix with a linear combination of the response components of the simple response matrix. The modified response matrix is inverted and an indication of formation properties in the geological formation is output.

  • Publication number: 20190383961
    Abstract: A system and method of evaluating a subterranean earth formation using a statistical distribution of formation data. The system comprises a logging tool and a processor in communication with the logging tool. The logging tool comprises a sensor operable to measure formation data and is locatable in a wellbore intersecting the subterranean earth formation. The processor is operable to calculate inversion solutions to the formation data, wherein each inversion solution comprises values for a parameter of the formation, and generate a statistical distribution of the parameter along one or more depths in the subterranean earth formation using the inversion solutions. The processor is also operable to identify peaks within the statistical distribution and select the inversion solutions corresponding to the identified peaks, generate a formation model using the selected inversion solutions; and evaluate the formation using the formation model to identify formation layers for producing a formation fluid.
