The March 31, 2014 agreement between Anticosti Hydrocarbons L.P. partners provided for an exploration program.

In 2014-2015 | Stratigraphic survey wells 
First, in 2014 and 2015, 12 coreholes were executed with four mining drills in order to take samples from the Macasty Formation, in compliance with the highest health, safety, and environmental standards.

The techniques used for stratigraphic survey wells are different than those used for petroleum drilling. For example:

  • Equipment has a smaller footprint (rigs are smaller and less equipment is required);
  • Drilling sites requires less area (30 m X 40 m for the site, 20 m X 20 m for the flare pit);
  • Hole diameters are smaller;
  • Holes are completely filled in with cement upon completion of work;
  • Holes cannot be used for production.

In 2017 | Fracked wells


The core samples taken from the Macasty Formation will be used to identify the best locations for three fracked test wells planned for 2017.

Drilling site preparation work to begin in 2016, in compliance with the North American oil and gas industry's highest standards.

The objective of drilling with fracturing is to assess the economic potential of hydrocarbons on Anticosti Island.

At the end of phase 1 
Based on the results obtained during the 2014–2017 campaign, our board will decide whether to start producing or to continue the project with a second phase of work consisting of additional petroleum drilling.

Government monitoring of Anticosti work 
The Government of Quebec has created a website on oil and gas exploration, including the Anticosti Island exploration program ( The website presents the government action plan on oil and gas development as well as the monitoring of Anticosti work.

What is stratigraphic survey well?

It is a technique for collecting data on geological formations through sampling and analysis carried out in the course of preliminary investigation with a view to locating, designing, and building a drill site to explore for or produce oil, natural gas, or reservoir brine, or an underground reservoir and the wells found there.

Upholding the highest standards

We will carry out our operations in a respectful and safe manner for the community, in compliance with the industry's highest standards. We have implemented a number of measures to reduce risk to a minimum. For example, for conducting stratigraphic survey wells, we will:

  • Install cemented surface casings: 
    Protects groundwater.
  • Use blowout preventers (BOPs): 
    Blowout preventers are fastened (cemented) to the surface casings to ensure employee safety and control the wells in the event of gas kicks.
  • Use a closed-loop drilling fluid system: 
    To limit the amount of water required, we developed a process for reusing water and recovering drill cuttings.
  • Provide employee training: 
    All drillers and driller assistants receive task-specific training.
