History Research in the Delaware Basin 2005
Geotrack is currently supporting Dr Richard Swarbrick of Durham University
(UK) and his post-graduate research student Tom Sinclair in an exciting
new study applying Geotrack’s AFTA-based thermal history reconstruction
technologies in the Delaware Basin of Texas. Geotrack’s research
support for the preliminary study involving 10 samples is worth more
than US$12,000. Anadarko and BP are also supporting this research.
The key aims of the study are to provide direct constraints on the
thermal and denudation histories in the basin, especially the timing
and magnitude of major periods of heating and cooling and the mechanisms
responsible. These results will provide a framework within which Tom
will investigate the mechanisms responsible for sub-surface pressure
distribution in the basin.
As far as we know, no other fission track thermal history studies have
been carried out in the basin, perhaps due in part to the perception
that apatite-bearing sands will be rare as a result of the preponderance
of limestone and evaporities in the Palaeozoic sedimentary section.
In a pilot study of 10 samples, 5 from outcrop and 5 from a deep well
sequence, apatite suitable for AFTA has been recovered from all samples,
with excellent yields obtained from eight of these samples. This points
to a successful study and reliable results.
Stay tuned for the results!
