  This section of the website gives access to certain specific information regarding the exploration activities in the Utica Shale.

 
  The St. Lawrence Lowlands region was the place, towards the end of 2007, of an important discovery of natural gas in the geological formation of the Utica Shale. This announcement created a real interest for gas exploration in the St. Lawrence Lowlands.

 
  The St. Lawrence Lowlands sedimentary basin contains a geological formation of calcareous shale particularly enriched in natural gas, the Utica Shale. This formation, located in the St. Lawrence valley between Montreal and Quebec, covers on surface and in sub-surface an area of about 10 000 square kilometers. The Utica Shale generally varies in thickness between 100 and 250 meters, reaching up to 750 meters in the Richelieu valley. The Utica Shale outcrops along the north bank of the St. Lawrence river, and deepens gradually towards the southeast to reach approximately 2.5 kilometers in depth along the Logan's Line fault. The Utica Shale is overlain by another shale formation, termed the Lorraine Group. Although these rocks also present a gas potential, the exploration activities presently focus on the underlying Utica Shale.
