ADDY, SUNIT K. , CGG Petrosystems, Houston, Texas
In this session, I would like to present a case history in which seismic facies maps were generated by Stratimagic, CGG Petrosystems' latest 3D stratigraphic interpretation system utilizing a neural network classification technology. The process is extremely fast and many facies classifications can be performed in a relatively short time for several horizon intervals in the seismic volume. This patented technology is licensed from Elf Aquitaine. In a 3D survey in central south Texas using seismic facies maps, we were able to identify porosity in Edwards limestone, define the Sligo reef trend, map complex channel systems in the upper Wilcox and Frio sections and determine the extent of lower Wilcox onlapping sands in the Lavaca channel.
The process is fast and the ability to create numerous facies maps quickly and repetitively in the beginning of an exploration phase enables the interpreter to effectively scan through the data and to concentrate in areas of significance.
