PowerLog

Advanced Modules

Four optional integrated products are available to extend PowerLog capabilities:

Capillary Pressure extends PowerLog analysis by allowing full analysis of pressure within pore throats (capillary pressure). The module includes an elegant loader for importing plug data, capillary pressure corrections and an array mathpack. Capillary Pressure generates models for water saturation as a function of height above free water level (FWL). This capability enables better recovery estimates as geoscientists can determine the wetting characteristics of reservoir rocks, the relative fluid distribution, connate water saturation and likely recoverable oil and gas.
PowerLog - RPM integrates the log analysis of PowerLog with rock physics elastic modeling. RPM enables a fundamental modeling approach—a petrophysical rock model is used to derive the effective elastic rock properties from fluid and mineral parameters, as well as rock structure information. The model parameters are calibrated by comparison of the synthetic to the available elastic sonic logs. RPM supports inclusion models and contact models including Stanford cemented spheres scheme. Industry standard methods include Xu & White, self-consistent, and Krief-Gurevich-Goldberg. Bound models include Voigt, Reuss, and Hill. RPM supports Hahin-Shtrikman upper and lower bounds, plus in-house velocity models. Gassmann fluid substitution and complete anisotropy support are also provided.

FaciesID™ lets you interactively select points on your logs and create and assign electrofacies classes. Once your seed points are assigned, FaciesID will classify the rest of the well for you. You can move seed points on either logplots or a crossplot just by dragging them to new locations. And you can change electrofacies classifications at will by simply selecting new categories from a drop-down list. FaciesID reporting includes indexes that tell you how dispersed and ambiguous are your electrofacies clusters. The reports tell you when you can really distinguish electrofacies classes from the logs you are using.

Statmin™ uses a probabilistic model to calculate lithology, mineralogy, and/or porosity and can easily adapt to the needs of the analyst. Any well log or computed curve that responds to formation bulk volumes can be used as an input. Statmin solves balanced, over-determined, and under-determined models. In addition to the mineral volumes, a reconstructed version of each input curve is computed and output.
