EXECUTIVE SUMMARY


The overall objective of this study as determined by the Sponsors was to 1) document stratigraphic variations affecting the distribution of reservoir quality sediments + HC-rich source rocks through the analysis of seismic and well data, 2) determine the rock maturation characteristics and chemistry of oils and rocks and 3) construct log controlled cross-sections that correlate to regional seismic profiles. The items listed below were integrated to form final interpretations:
 

  • Tectonic and sediment transport overview
  • Regional Cross-sections
  • Seismic Profile Interpretation
  • Stratigraphic Columns
  • Reservoir Characterization Petrology/Petrography
    Formation Waters
    Clay Data
    Mineralogy of Reservoirs
  • Geochemistry of Rocks and Oil


    Of the 199 rock samples studed, 71 thin sections were cut for petrographic description and initial reservoir characterization. These samples were also used for biostratigraphic interpretations, source rock analysis, maturation and stable isotope work. The distribution of these samples - geographic and stratigraphic - is shown on maps, along with detailed tables of the data. A CD is included showing these thin sections. 85 oil samples were collected from wells and seeps and the distribution is noted in tables. These samples were used in several analytical procedures to attempt to categorize them into families and biomarker interpretations.


    Regional cross sections are included as enclosures to this report and regional stratigraphic interpretations made from log and seismic sections, although limited, are also included in this year study. An extensive bibliography has been accumulated.
