SCOPE OF REPORTS

These reports provide a comprehensive description and interpretation of the lithology, facies, stratigraphy and diagenetic history of the main prospective sedimentary succession of Iraq and Syria. Reservoirs and seals are thoroughly documented, intervals with significant organic richness and oil shows are identified. Summaries of tectonic setting and other background information are also included. The results are placed in their broader context and exploration implications assessed, including discussion of established and new plays.

SAMPLE COLLECTION AND ANALYSES

The University of Reading Middle East Archive contains a vast number of thin sections made from core, cuttings and outcrop samples. The thin sections were prepared on the rig site for many of the wells at 5 or 10 feet intervals throughout the complete penetrated section. These have been examined and described using petrographic microscopes. New epoxy-impregnated thin sections have been prepared from core and cuttings samples over critical intervals. Selected intervals have also been analysed using palaeontology/palynology, SEM and XRD techniques.

REPORT FORMAT

The format of each report is similar. A detailed petrographic log is presented for each well at a scale of 1 inch : 100 feet, with an accompanying well report giving full documentation and interpretation of the petrographic and supplementary analyses, including numerous photomicrographs to illustrate typical lithofacies, porosity types and other significant features. The results from the individual wells are drawn together in a regional synthesis and interpretation volume which includes discussion of the implications for petroleum exploration. The regional synthesis is illustrated with well correlations, isopach and facies maps, depositional models, summaries of tectonic settings etc.

The first three petrographic reports on North Iraq and Syria were based entirely on cuttings and core samples without access to wireline logs. These logs and other well data were subsequently donated to the Reading Archive and were incorporated into the later reports. All the wireline logs have now been digitised (See Overview Report) and we are currently digitising all the lithological data. As part of this digitisation process the northern Iraq wells will be reinterpreted to tie into the wireline logs.

Report Title

Palaeozoic of Iraq and Adjacent Areas: Petroleum Geology and Exploration Potential

Price & Date Price £30,000, Completed 1999
Contents Summary

This report provides a regional interpretation and data base for the Palaeozoic of the northern Middle East focusing in particular on the Western Desert of Iraq.The primary data source for the report is new analysis of well and outcrop samples from Iraq, Syria and Jordan, supplemented by well logs and other published data from Turkey, Syria, Iraq, Iran, Jordan, Saudi Arabia and Kuwait.

The study is based on new petrographic descriptions and covers the entire Palaeozoic succession. New geochemical analyses has been undertaken on potential source horizons to assess variations in source potential and maturity. New dating has been undertaken to improve and constrain correlations.

The results of these new analyses have been incorporated with other available published and proprietary data into a regional synthesis of the Palaeozoic sedimentary geology of the northern Middle East with special emphasis on the exploration potential of the Western Desert of Iraq.

The report covers lithofacies types and distribution, reservoir potential, source rock development distribution and maturity, reservoir quality, sealing potential, regional tectonic history and structure, and exploration implications. The relationships between the different systems of stratigraphic nomenclature employed throughout the study area are explained within the context of the regional geological evolution.

  • 11 Petrographic logs and reports are provided for 7 wells and 4 outcrop sections - The total logged section is approx 39,000 feet.
  • 4 Composite logs.
  • 330 Photomicrographs.
  • Geochemical analyses (TOC, Rock-Eval, Ro Equiv, GC, GCMS)

Sedimentary Geology of the Mesozoic Outcrops of Iraq - Correlations to the Subsurface and Implications for Hydrocarbon Exploration

Price & Date Price £30,000, Completed 2003
Contents Summary

The primary aim of this project is to provide detailed petrographic descriptions of key outcrop sections from Northern and Western Iraq and to correlate these to well control points in adjacent areas.

The report provides a detailed account of the Mesozoic sedimentary geology of the Mesopotamian Basin in Iraq. Current sequence stratigraphic models for the basin are discussed, developed and refined, together with discussion of the implications for petroleum exploration in Iraq. The report also has relevance to exploration geologists working on the adjacent areas of Iran, Kuwait, Jordan and Syria.

  • Petrographic logs and reports are provided for 6 outcrop locations - The total logged section is approx 14,000m, 43,000 feet.
  • 1250 Photomicrographs.
  • 16 Maps and Correlation Panels, 270 A4/A3 figures.
  • Geochemical analysis and dating of selected intervals.
Authors Petroleum Geological Analysis Ltd, Quantock Geolgical Services, Saker Geolgical Services, The University of Reading

The study is based on measured outcrop sections from locations in Northern and Western Iraq which form part of the University of Reading Middle East Archive.

The Archive contains bed by bed field descriptions, plus thin sections and hand samples of the representative lithologies in each bed. The outcrop sections were originally measured, sampled and described, mostly in the 1950’s, by geologists of the Iraq Petroleum Company and were used, together with IPC well control, to establish the stratigraphy of Iraq as published in the Lexique Stratigraphic International (1959).

Samples in the Reading Archive include most of the formation type sections described in the LSI. This new study will provide detailed logs and descriptions for these sections based on modern concepts of stratigraphy, lithofacies and basin development.

This is the ninth study we have undertaken based on the Reading Archive. It compliments the earlier work by extending the regional picture from the Mesopotamian Basin margin, represented by the outcrops of the Western Desert of Iraq, through to the more distal portions of the basin, represented by the Zagros mountain outcrops.

Report Contents Summary

Detailed logs are provided for each of the analysed outcrop sections, with a summary text illustrated with photomicrographs. The results are discussed in their regional context with illustrative correlations into key wells across the study area and conclusions on the implications for the petroleum exploration potential. The report is in PDF format with additional digital data provided in LAS, spreadsheet and GIS formats. The detailed logs show the original field descriptions, the new petrographic descriptions, results of dating and geochemical analysis, interpretations of depositional environments and stratigraphy.
