HOUSTONTGS and PGS are working with Bain Geophysical Services to develop a new regional overview of the crust offshore Newfoundland and Labrador.

The Eastern Canada Crustal Study, launched earlier this year, will create 3D models including depth to magnetic/crystalline basement, depth to Curie isotherm, depth to Moho and crustal thickness, from the integration of seismic mapping and gravity and magnetic inversion and modeling.

Will Ashby, senior vice president North America for TGS, said: “We are particularly pleased that the delivery schedule will provide our early participants results in time to impact their exploration evaluation for the upcoming lease sales.

“This type of regional study helps to better understand the basic geologic framework for the area, and test alternative geologic interpretations, particularly beneath the shallower, more easily imaged horizons, so as to fully assess the crustal thickness and its effect on the petroleum system of this vast region.”

TGS also worked with BainGeo on the recently completed Gulf of Mexico/Gigante Crustal Study, designed to improve understanding of the petroleum system offshore Mexico.

In addition, shareholders of TGS have approved the company’s takeover of Spectrum. Closure of the transaction should follow during 3Q.

Kristian Johansen, CEO of TGS, said: “Spectrum’s portfolio will enhance TGS’ position as a leading multi-client geophysical data provider covering all mature and frontier basins.

“Spectrum’s extensive 2D library also furthers TGS’s data analytics strategy, where access to large amounts of data is a key success factor.”
