Gedco - Calgary

CHAD Data was formed in April, 2012, as a spinoff company from GEDCO.

In recent years, GEDCO focused its efforts on sales and services related to its seismic software products and their extensive database of gravity and magnetic data was not marketed. To rectify this situation, a few GEDCO shareholders and an outside investor formed CHAD Data and bought the gravity and magnetic database of GEDCO in order to focus on licensing that data to interested parties.

The name CHAD has no connection with Africa or Florida elections – it is simply an anagram made up of the initials of the two largest shareholders, Henry Dunfield and Andreas Cordsen.

Our web site contains a complete description of the available data. We hold an APEGA Permit to Practice and are able to setup Master Service Agreements with larger companies, if appropriate.

CHAD’s High Resolution AeroMagnetic (HRAM) data covers large parts of the Western Canada Sedimentary Basin in Alberta and BC, as well as most of the Canadian part of the Williston Basin in SE Saskatchewan. These data were all acquired with GPS technology and have been culturally edited to remove most manmade magnetic artifacts. The data quality is as good as one could acquire today – perhaps better in areas where there has been extensive development (and new magnetic sources introduced) in the last decade.

CHAD’s gravity data base covers a wide range of vintages from older land based data in parts of the Mackenzie Delta and AB/BC Foothills through extensive on ice coverage in the Beaufort Sea to two airborne data sets acquired in 2000. The Turner Valley data set is one of the best-documented and studied airborne gravity data sets available anywhere.

CHAD offers interpretive services for its data through Ted Glenn, a very experienced interpreter and structural geologist with both oil and mining experience. Ted uses CHAD’s copy of Oasis Montage (Geosoft) for data filtering, etc.

CHAD also owns the proprietary rights to MAG3DPRO, a software package for performing various kinds of magnetic depth solutions on profile and gridded magnetic data. This software has fixed several bugs that exist in the commonly used implementations of Werner and Euler 3D depth solutions, and has had excellent results when used in areas where there is good well control for comparison.
