PfEFFER Version 2.0/Pro is a cost-effective and practical tool for the real-time, interactive log analysis developed by the Kansas Geological Survey (KGS). PfEFFER stands for Petrofacies Evaluation of Formations for Engineering Reservoirs. Spreadsheet database and graphic features allow both rapid interaction and comparative evaluation of multiple interpretations or best case/worst case extremes. In addition, multiple wells and zones are easily managed. A project file can be generated that assembles reservoir parameter, grids them and displays them as 2-D maps or 3-D surfaces. Current version, 2.0/Pro, is written in Visual Basic for Excel 97 and was released in February, 1998. Software is sold through the KGS and a bundled version for Microsoft Office 2000 is distributed by Technical Toolboxes, Inc in Houston, TX.
PfEFFER Mission
Petroleum industry and the geoscience enterprise as a whole are making rapid advances in "digital data mining". Tens of thousands of wireline logs are available for more comprehensive analysis. Application of evolving geologic and engineering concepts and access to and processing of this digital information including well logs is creating opportunities to resolve geologic complexities and reduce risks in petroleum exploration and development. Low–cost, user-friendly, portable software can assist in the data mining effort and solve long-standing problems for scientific and economic gain.
Development of PfEFFER 3.0
Each version of PfEFFER has its own strategic concept that introduces new modules in addition to tactical improvements in options that are normally associated with software upgrades. PfEFFER v. 3.0 will build on the base of earlier versions of PfEFFER preserving simplicity in conducting basic log analysis augmented by "intelligent" features for automated prediction and classification tasks. Additions to PfEFFER will integrate core petrophysical algorithms for improved reservoir characterization. Also, definition of pay will be extended to include both concepts of flow and storage. Building map grids and developing data files of reservoirs for reservoir simulation was introduced in PfEFFER-Pro. The volumetrics and material balance modules will expand engineering application of well log analysis significantly.
The software coding for PfEFFER v. 3.0 is well advanced. The time is ideal to launch another consortium to participate in testing and evaluating new modules to ensure that PfEFFER remains an effective and practical tool for real-world, real-time applications. Total anticipated budget for Phase III development is $70k.
A greatly enhanced version of the software will be sought through combined funding from DOE and industry consortium. Funding level is estimated at $1.5 MM for three years. Research concepts to be employed in this enhanced version include:
