Ressources et Energie Squatex Inc. announce the discovery of a significant reservoir rock which could contain a large quantity of conventional natural gas in the Lower St. Lawrence area. While carrying a stratigraphic coring program which started in 2010 to evaluate the oil and gas potential of its licences, important porous dolomitized limestone zones of hydrothermal origin containing gas (89%Methane) were met in a core hole that reached 1874 meters in the Mitis River area, south of Rimouski. These horizons of the Sayabec Formation are covered with fine grains rocks of the St-Leon Formation acting as cap rocks. A similar porous horizon was already known outcropping near St-Cléophas in the Matapedia, some twenty kilometers more to the east.
The core hole Massé No.1 was aimed to test a series of seismic AVO (amplitude vs offset) anomalies indicating the possibility of the presence of fluids and/or porous reservoir rocks near thrusted zones. The cores collected starting at 1847m where important gas flows started to occur, exhibit a 10 meters thick zone which contains a measured porosity which locally reaches 20,8% with a permeability of 1624 mD.
