Hectori Technology

Hectori actively conducts the magnetic horizontal gradient and radiometric surveys described at this website on its own account, for partners, or for the oil and gas industry at large. Photographs of our field operations are available online to provide interested parties with a concept of how logistically simple and non-intrusive our surveys are. Magnetic surveys are conducted on foot to avoid the contaminating magnetic influence of survey vehicles. When radiometric surveys are conducted concurrently with the magnetics, a low-ground-pressure vehicle, such as an ATV or 8-wheel-drive ARGO is used to carry the gamma-radiation sensor and spectrometer. Data locations in the field are recorded by GPS.

For geologists and geophysicists examining our site, we provide technical details that can be downloaded as follows:

  1. The most comprehensive discussion of Hectori's geochemically-based surface exploration survey technology is given in: High-Resolution Ground-Magnetic (HRGM) and Radiometric Surveys for Hydrocarbon Exploration: Six Case Histories in Western Canada*; written by Leonard A. LeSchack of Hectori Inc. and David R. Van Alstine, of Applied Paleomagnetics, Inc. This is Chapter 5 in the above-mentioned AAPG-SEG book and can be accessed from this web page.  A short summary of this paper taken from the "Introduction" of the AAPG-SEG book is presented below:

"Leonard LeSchack and David Van Alstine use high resolution ground-based magnetic and radiometric surveys successfully for hydrocarbon exploration in Western Canada and present six case histories. From the science of paleomagnetism they observe that it is possible to identify which of several stacked reservoirs leaking hydrocarbons has caused a specific near-surface diagenetic magnetic anomaly to occur. This capability permits focusing on more prolific Devonian targets even though these reservoirs are overlain by less economic Cretaceous oil and gas fields. The results of over 100 wells from these case history areas were compared with their associated magnetic signatures, permitting meaningful trends to be developed which have proved valuable for further exploration in Western Canada and, likely, throughout the world. The authors claim 85% success in predicting new field discoveries using magnetic and radiometric surveys, and have suggested reasons why tectonic and hydrocarbon maturation studies support the development of distinctive clusters of magnetic data for different reservoirs in the Western Canada Sedimentary Basin. The authors show that, at least in Alberta, by correlating high resolution aeromagnetic data with their ground-based magnetic data, it is also possible to interpret diagenetic anomalies observed in airborne data for use in predicting the prolific Devonian targets and to focus where to conduct more definitive ground-based surveys."

2.     Hectori Inc discovered a Leduc pinnacle reef in Alberta using only magnetic HG' and passive tellluric surveys. Upon drilling in 2002, Hectori found their predicted reef within 10m (30') of its estimated depth. This discovery has been described in "Surface Exploration Successful in Finding Alberta Leduc Pinnacle Reefs," 2004 AAPG Annual Convention, Dallas 18-21 April. The extended abstract may be accessed from this web page.
