NON-EXCLUSIVE REPORT BASED
ON NEW AFTA® AND VITRINITE REFLECTANCE DATA
IN ASSOCIATION WITH SPECTRUM ENERGY
AND INFORMATION TECHNOLOGY LTD
reconstruction is a critical aspect of exploration acreage evaluation.
This project has, for the first time, acquired reconnaissance data on
the hitherto unknown thermal history of the Falkland Islands region.
The report includes a reconstruction of the Paleozoic to Tertiary thermal
evolution of the outcrop area, based on interpretation of new AFTA and
vitrinite reflectance data. The results are important in the evaluation
of the thermo-tectonic evolution of the Islands and to the proper understanding
of the petroleum system, providing key constraints for modelling maturity
development in potential source rocks and prediction of hydrocarbon
generation in the offshore basins.
THE REPORT INCLUDES:
- AFTA data from 17 outcrop samples
(Pre-Cambrian, Ordovician, Devonian, Carboniferous, Permian and Triassic).
- High quality vitrinite reflectance
data from 13 outcrop samples (Devonian, Permian, Permo-Triassic),
including histograms and full organic maceral descriptions.
- Rigorous interpretation of AFTA
data using Geotrack's multi-compositional apatite annealing model,
including microprobe analysis of all apatite grains for compositional
- Thermal history reconstruction
based on integration of AFTA and VR data, including recognition of
key paleo-thermal episodes, the time of cooling from maximum and subsequent
peak paleotemperatures, and estimates of the maximum and peak paleotemperatures
experienced by each sample.
- Geological background to the
Falkland Islands, description of regional geology and summary stratigraphy
of offshore basins predicted from seismic data.
- Regional synthesis and implications
for hydrocarbon prospectivity.
