FALKLAND ISLANDS
NON-EXCLUSIVE REPORT BASED ON NEW AFTA AND VITRINITE REFLECTANCE DATA

GEOTRACK INTERNATIONAL IN ASSOCIATION WITH SPECTRUM ENERGY
AND INFORMATION TECHNOLOGY LTD

Thermal history 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 data.
  • 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.
