TGS, through its wholly-owned subsidiary Arcis Seismic Solutions, begins multi-client energy survey of Ille Lake in Central Alberta, Canada. The lake, popular with anglers and nature-lovers, covers 180 km2 (70 mi2) in the deep basin of Central Alberta, Canada. The Ille Lake survey is optimized and designed to evaluate multiple zones from the Cardium and the Upper & Lower Mannville (Glauconite, Ostracod & Basal Quartz Oil), through to the newly emerging Duvernay unconventional play. In addition to the survey's optimal acquisition parameters, Arcis provides proprietary tools that will enhance imaging and rock property assessments for even greater assistance with the placement of horizontal wells.
