EXECUTIVE SUMMARY

This report presents the results of a study carried out as a colloborative effort by the Energy & Geoscience Institute at the University of Utah (EGI), the Balkan Research Petroleum Institute (BalkanNIPINeft) in Nebit-Dag, Turkmenistan and the Geology Institute of Azerbaijan National Academy of Siences (GIA) in Baku, Azerbaijan. The involvement of BalkanNIPINeft took place under the auspices of the Turkmenistan Polytechnical Institute (TPI) in Nebit-Dag.

The study which commenced on February 1, 1997, was performed by scientists from EGI, BalkanNIPINeft and GIA, using data supplied by BalkanNIPINeft and GIA. Most of the work wsa done in EGIs offices in Salt Lake City. The database which is specified in detailed in individual chapters of the report, consists essentially of core samples, wireline logs, oil samples and seismic lines from both offshore and onshore areas of Turkmenistan (Enclosure 1.1).

The report comprises four volumes. The first covers the regional structure and stratigraphy of western Turkmenistan, and includes a sequence-stratigraphic study of the Red Series. Volume II examines the nature of the reservoirs in the Red Series, based mainly on petrographic observations, and identifies the factors controlling variations in small-scale reservoir quality. Volume III characterizes the pertoleum charge system using both conventional geochemical and thermal-modeling techniques and also a novel statistical method of analyzing oils data. Volume IV presents displays summarizing field geology; information on poduction tests; pressure decline and formation water composition; and core analysis data, including results of mercury capillary pressure analysis, for individual field. In addition this volume contains thin-section photomicrographs for fields from which core samples were available.
