EXECUTIVE SUMMARY

This study for the first time puts together data from several areas of the Caspian Basin selected for a multi-disciplinary analytical approach. The three sample sets are shortly described hereafter:

The Organic Geichemistry sample set consisted of:
Samples:
12 Outcrop samples
49 Oil samples
289 Core samples
Areas covered:
Baku Archipelago
Absheron Peninsula
Lower Kura Depression
Shemakha-Gobustan
Absheron Sill


The analyses include:
Part 1: Organic Geochemistry
TOC, Rock-Eval, GC, GC / MS, MSSV, Osotope ratios, Fission Track, Sulfur content, API Gravity, etc.

The Biostratigraphy sample set consisted of:
Samples:
59 Outcrop samples
 
289 Core samples
Areas covered:
Baku Archipelago
Absheron Peninsula
Lower Kura Depression


The analyses include: Part 2: Biostratigraphy
Palynology, Foraminifera, Ostracods, Nannofossils and fish remains.

The Sedimentology sample set consisted of:
Samples:
~130 Core samples
Areas covered:
Baku Archipelago
Absheron Sill
Lower Kura Depression


The analyses include:
Part 3: Sedimentology
XRD, SEM, Petrology, Porosity and Permeability


The study specifically encompasses:

  • the type outcrop sections in the Absheron Peninsula: Mehtiabad (Maykopian, Tarkhanian and Chokrakian),
  • the Kirmaky Mountain (Pontian),
  • the Kirmaky Valley (Lower Productive Series - PK, KS, NKS, NKG Suites; Upper Productive series - Pereryv, Balakhany Suites),
  • the Beyuk-Shore (Upper Productive Series - Balakhany, Sabunchi, Surakhany Suites) and
  • the Lower Kura Depression: Babazanan (Upper Productive Series - I Babazanan Suite)


The outcrop sections were studied and correlated with the well sections, which will be useful for the understanding of the Stratigraphy and Biostratigraphy of potential reservoirs and potential source rocks.


The three parts stand by themselves and this particular copy might or might not have all three parts depending on the license acquired. The combination of the area and the disciplines is unique and will serve the reader well in understanding the hydrocarbon system of entire area. We believe that the completeness of the data presented here will make this report a data repository that is worthwhile coming back to again and again. To make the access to the data more conevient and increase the utility of the product as much as possible of the data has been provided on disc. All data presented has been produced or subcontracted by APTI and GIA. Utmost care has been taken to provide correct identification and classification in all parts of the study. However, as with all original work, some misidentification might have escaped our quality control efforts.


Individual introductions to the three parts of the study lead into each discipline. Location maps are provided for each sample set. The sample sets for Biostratigraphy, Organic Geochemistry and Sedimentology overlap considerably but are not identical. Tis gives the reader the opportunity to investigate a significant portion of the study area in great detail. The biostratigraphic data is collated by structure, whereas the geochemical data is provided on a sample basis in the order the samples were analyzed. Especially the geochemistry data has been provided with location and formation information, which will allow theuser to retieve and sortr the data in any desired way.


This report intentionally stays away from detailed interpretation of the complex area but rather provides data, graphics abd software to enable the reader to draw conclusions in light of additional geological information that is might be available to your company. The scientists behind the study (see list of contributors) are available to you for integration of the study with other data, additional analyses, or related projects.
