Abstract: Hybrid inversion processing techniques are implemented that result in improved speed and accuracy of determining formation properties using log data, for example, from an multi-component induction logging tool. Logging data relating to the formation of interest is obtained and used as an input. High frequency noise is then removed from the logging data and bed-boundary determination is performed using the logging data. An adaptive low pass filter is applied to the logging data and the logging data is inverted. The inverted logging data is correct and enhanced by determining one or more weights based on one or more quality indicators. The inverted logging data may then be visually interpreted and used to adjust one or more drilling parameters.

Abstract: A method for real-time determination of water-filled porosity of a formation using dielectric measurement data, whereby the refractive index of a non-water component of the formation and the downhole temperature are acquired, along with the dielectric constant of the formation. Using these values, the water salinity of the formation is calculated. Calculation of the water salinity involves the use of a complex nonlinear equation having multiple solutions. A theorem is applied to the nonlinear equation which produces a single proper solution. Once the water salinity is calculated, it is then used to calculate the water-filled porosity of the formation.
