Log-analysis software available from the Survey

LAWRENCE--A new software package for real-time, interactive analysis of well logs is now available from the Kansas Geological Survey, based at the University of Kansas.

The program, called PfEFFER (Petrofacies Evaluation of Formations for Engineering Reservoirs) Version 1.0, includes both spreadsheet database and graphic features for analyzing well logs. It was developed by Survey geologists John Doveton, Willard Guy, and Lynn Watney.

PfEFFER helps geologists interpret and analyze reservoir pore type, permeability trends, and variations in mineral composition of the reservoir. The software can also help geologists evaluate potential production, reservoir quality, and heterogeneity.

The software, developed with support from the Kansas Technology Enterprise Corporation and 12 oil companies, includes modules that can

• read log ASCII standard digital files,
• construct a "Super Pickett" porosity-resistivity crossplot annotated with lines of water saturation, bulk volume water, and permeability,
• draw depth plots of parameters,
• solve proportions of complex lithologies,
• analyze capillary pressure, and
• produce 2-D or 3-D maps of the reservoir.

Both Macintosh and IBM versions of the software are available. The software requires a minimum of a porosity and resistivity log and can utilize both previously digitized logs or those typed in.
