fracture stim designs
Dew,
i'm guessing that "low tech geometric designs" refers to fracturing experiments carried out in labs. Many of those operations aren't particularly low tech and I'd bet that many of the 'petrophysical data sets' were derived from or are calibrated against similar 'low-tech' experiments. However, the 'data sets' that the PR refers to are probably from downhole logging tools. Continuing with semi-educated guesses: i suspect the 'effective' stimulation programs are derived from a combination of first principle calculations, averaged rock properties, regional stress analyses, and old-fashioned empiricism. In addition, sometimes scale matters and the scales involved in this stuff are difficult to accommodate in the lab.
cheers,
Charlie
