Historically, both 2D and 3D seismic data have proven of limited value in petroleum exploration in the Wilcox Group (Paleocene-Eocene) of central Louisiana. Modern, conventionally processed 3D seismic data are useful for general sequence stratigraphic interpretation (e.g., delineation of sequence boundaries) but do not have the vertical and horizontal resolution required to image the details of fluvial-deltaic stratigraphic features used to identify subtle hydrocarbon traps. Our processing of existing 3D seismic data, using propriety software algorithms, sufficiently enhanced the seismic data resolution to make it an effective tool for petroleum exploration in fluvial-deltaic strata.
The processed seismic data have been calibrated with geological information and synthesized with previous stratigraphic interpretations of the Wilcox Group in the region. The high-resolution seismic data make recognizable subtle hydrocarbon trapping situations that result from sand pinch-outs and differential compaction. When integrated with the subsurface data, it is possible to create a more detailed stratigraphic framework for use in a hydrocarbon exploration program.
