Libya - Sirt Basin - A New Petroleum Systems Analysis

Lynx has released (Q4 2009) a new, GIS-enabled Petroleum Systems Analysis of the Sirt Basin, authored by David Boote of DB Consulting, a recognised expert in North African geology.

This major, integrated study provides a regional petroleum systems framework for:

play analysis and risking
prospect highgrading/ranking and risking
extending existing play trends
and developing to play concepts/ideas

The report contains a comprehensive series of regional facies maps supported by:

basin-wide stratigraphic correlations
detailed stratigraphic sections illustrating local stratigraphic architecture
a regional analysis of oils, identification of key oil families and provisional oil-to-source correlations
basin-wide burial history reconstructions
regional generative area expulsion / migration models

1/10 The study draws upon an extensive inventory of interpreted maps, well and seismic
data, including 3000+ wells with tops and 1000+ with wireline data

2/10 Tectono-stratigraphic evolution described by 13 regional stratigraphic correlations,
in concert with facies maps and facies sections depicting the unfolding paleogeography of the
area

3/10 Key horizon intervals were mapped using tops data, and modelled for source maturation
using regional 1D basin models

4/10 The maturation reconstructions were then integrated with source rock distribution maps
to create source kitchens for each recognised source horizon through time

5/10 An analysis of over 150 broadly distributed oil samples from across the Province, used
to identify and map a number of discrete oil families. These were defined by their Δ13C and
Pr/Py character and described using cross plots and maps with supporting text and tabulation
listing the family (group) of each oil by stratigraphic horizon

6/10 Charge models in both section and plan views were constructed by overlaying field pool
locations, source generative areas and the oil family maps, allowing migration pathways to be
drawn for each contributing source rock through time

7/10 A systematic effort was undertaken to tabulate oilfield data describing stratigraphy,
reservoir character and estimated reserves for all significant hydrocarbon discoveries. Field
analogue data were also gathered and synthesized from open file published field data

8/10 Play summary maps were constructed in ArcMap for 13 recognised petroleum systems,
making use of the ArcGIS layer framework to quickly assemble context-related maps

9/10 The ArcGIS deliverable forms an interactive toolkit for reasonably experienced users
to create combined risk segment maps, a popular method for assembling play risk and chance potential

10/10 The ArcGIS deliverable is dynamically coupled with a 450-page tectono-stratigraphic
report, which details the key aspects of the study and also includes an appendix updating the
classic Barr & Weegar treatise on Sirt Basin lithostratigraphy

This report is one of a series of GIS products designed to exploit the power and ease of use of ArcGIS as a tool for the Explorationist. The product consists of a wide variety of exploration and production related maps linked to well/field databases, well logs and seismic sections managed from within ESRI's ArcGIS application suite. Text, tables and figures are also provided as digital PDFs.

This GIS digital exploration package is organised into several modules:

Medina Bank (pdf)
