SPE J. 12 (06): 531–540.
Paper Number: SPE-3526-PA
Published: 01 December 1972
.... Excellent agreement was found between these results and the qualitative indication of rock wettability obtained from native-state or fresh core relative permeability tests. The tests further showed that contamination by air and certain metallic ions can seriously alter the wetting properties of many...

..., more ef- ficient, and substantially less expensive to perform. For qualitative interrogations of complex rock for- mations, The University of Texas at Austin developed UTNuPro to compute macroscopic nuclear parameters. It is a successor to the venerable SNUPAR program that supports more elements...

This increase in resolution in combination with AVO-compliant processing will provide more detailed spatial prediction of rock and reservoir properties from quantitative interpretation workflows. Future work will focus...
