INTRODUCTION - Petroleum Geochemistry Reports

Two reports based on organic geochemical analysis have been completed. The first is a regional source rocks study based on 38 wells from Lebanon, Syria, Iraq, Qatar, UAE and Oman. The second provides biomarker correlations between source rocks and oil residues from Iraqi wells.

NEW FOR 2010 - The price of the PGME study has been reduced from £84,000 to £42,000 - Prices for individual wells have also been halved.

PROJECT AIMS

The aims of the report are:

  • To identify the main potential source rocks of the region and to assess their richness, maturity and the type of hydrocarbon likely to be produced.
  • To model the burial history of the potential source rocks in order to assess time of generation and migration, both at the well data points and in the main potential generating areas.
  • To place the geochemical results in the broader context of the petroleum geology to provide an appraisal of the Middle East province, both locally around the data localities and, by extrapolation, of the whole region from the Syria-Turkish border through Iraq to the Southern Gulf.

ANALYTICAL PROGRAM

Lithological logging

Basic mud log-style lithological logs were compiled by examination of the core and cuttings material from surface or near surface to total depth in 26 wells.

Geochemical analysis from surface to TD in 21 Key Wells

Based on the lithology logs, 21 wells were selected for screening from surface to TD for TOC content. All intervals with dark lithologies were analysed. All samples with TOC greater than 0.5% were then subjected to Rock-Eval style pyrolysis. Based on these results intervals were selected for more detailed analysis of kerogens by PYGC, and soluble extracts by GC and GCMS. Kerogen types were determined visually and maturity estimated from spore colour and vitrinite reflectance where possible. Carbon isotope analysis was also performed on selected intervals.

Geochemical analysis of selected intervals in 17 Subsidiary Wells

Based on the results from the key wells, intervals of interest were selected and geochemically analysed in a further 17 wells.

DIGITAL DATA

The numerical data (but not the gas chromatograms) are now available in Excel spreadsheet format.

TOTAL NUMBERS OF SAMPLES ANALYSED

975 sample intervals have been analysed from 38 wells. Samples range in age from Ordovician to Tertiary. A total of 924 samples were analysed for TOC of which 345 were further analysed by Rock-Eval pyrolysis; Solvent extract analyses were completed on 186 samples and 21 were further analysed by GCMS; Visual kerogen descriptions were completed for 231 samples; Vitrinite reflectance measurements were completed on 169 samples; Carbon isotope ratios were determined for 38 samples.

Oils, Shows and Source Rocks of Iraq: Source Rock and Oil Character, Biomarker Correlations and Exploration Implications

Price & Date Price £30,000, Completed 1993.
Contents Summary

Biomarker Correlations between source rocks and reservoired oils and shows.

24 oils and shows and 27 source rock solvent extracts have been analysed in this study by gas chromatography (gc) and gas chromatography-mass spectrometry (gc-ms.)

The aims of the study are:

  • To characterise the oils and significant shows of Iraq, for which samples are available in the University of Reading Middle East Archive, by identification of biomarkers.
  • To analyse solvent extracts from significant source rock horizons to determine the biomarker character of each source and then to suggest oil-source correlations.
  • To present and discuss the results with particular emphasis on the results which appear significant for acreage evaluations and exploration assessments.

Location of analysed wells

INTRODUCTION

In this project, extracts from potential source rocks, extracts of oil residues from productive reservoirs, and extracts from significant shows have been analysed by gas chromatography and gas chromatography-mass spectrometry. Biomarker and other data generated were used to evaluate the depositional environments and maturity of the extracts and to correlate between the source rock extracts and the reservoired oils and shows. The source rock intervals were also selectively analysed to assess source quality by standard TOC + Rock-Eval pyrolysis and pyrolysis-gas chromatography.

Intervals for analysis were chosen to characterise oils from the main productive reservoirs for which samples are available in the University of Reading Archive. In addition, significant shows noted during the course of the facies-stratigraphic studies, and shows noted in the IPC well records were also selectively analysed. These were chosen to help investigate new plays, particularly in the Jurassic and Triassic section, which has great potential, but little established production in Iraq. The source rocks were selected based on intervals with significant organic richness identified in the original source rocks geochemistry project and the facies-stratigraphic projects.

REPORT CONTENTS

The report is provided as five PDF report volumes with associated numeric data in Excel spreadsheets. Volume 1 presents results and interpretations in their regional context, and discusses implications for future exploration in Iraq. Volumes 2-5 present the results and interpretations of individual samples on a well-by-well basis.
