Thirty-six oils from 19 fields in the Sirte Basin, Libya have
been analyzed by state-of-the-art analytical techniques to
assess:

Sirte Basin, Libya.
- oil types and genetic relationships
- inferred source lithofacies
- source maturity
- oil alteration/ charge history
- generation temperatures
- rates of oil generation
Data available on these samples include:
- physico-chemical properties
- high-resolution light hydrocarbon whole oil fingerprinting
- carbon isotopes
- biomarker analysis including MS-MS
- source rock kinetics
- detailed interpretive report
- complete digital data package
The complete data package with interpretive report: $15,000.00

Saturate and aromatic biomarkers were utilized to type and
correlate oils, as well as assess thermal maturity. Oils were typed
into separate groups based on hopanes, steranes, and triaromatic
steroid biomarkers. MS-MS data were utilized to access depositional
environments and oil ages.
Figure 2: Source-specific biomarker data were
used to group the oils analyzed from the Sirte Basin.
Figure 3: Oil typing based on light
hydrocarbon distribution show some differences from biomarker
groupings.
Light hydrocarbons, which were used to type the condensate range
hydrocarbons, were particularly useful for evaluating retrograde
condensate-oil mixes.In reservoir oil alteration, including
biodegradation and evaporative fractionation, were evaluated. The
presence of retrograde condensates was assessed and implications
for future exploration efforts detailed.
Kinetic data have been acquired both on effective source rocks
and oil asphaltenes. Kinetic data are used to model the rate of
kerogen conversion into hydrocarbons, and are essential for
accurate modeling of hydrocarbon generation. For detailed modeling,
compositional kinetics and yields are available on the Sirte Shale
as an add on to the data for $5,000.00.

generation from various source horizons can be determined from bulk
kinetic parameters. Measurements made directly on source rocks and
oil asphaltenes provide optimum data for basin modeling.
