GSI has developed a new in-situ gasification extraction process with great potential for recovering oil and gas from oil shale and oil sands deposits.

GSI technology overview

GSI's technology stands out in a class of new oil shale production methods called in-situ processing technologies. Within the class of in-situ production technologies, GSI's patented process has several unique features that promise an environmental and economical breakthrough for recovering oil and gas from oil shale and tar sands deposits.

Single well design

The single well design is used in which a heat distributing inlet conduit is inserted into a gas effluent outlet conduit.


Gas flow management

Our gas flow management system ensures control of oxygen content and movement of effluent gases towards the outlet conduit.

Expanded Recovery

The GSI process is not limited to extracting products only from the “Mahogany Zone” but allows for recovery from the entire well cross-section, making possible cost-effective recovery from many areas not useable by other processes. The GSI heating and recovery systems are also well suited for product recovery from oil sands deposits.


Condenser and treatment system

Our condenser and treatment system safely separates the various grades of oil products and associated lighter gases (hydrogen, methane, propane, butane etc.) above ground.


Co2 geosequestration

The GSI process post-recovery leaves behind a unique sub-surface environment in the form of a large surface area of charred pores that adsorb high amounts of carbon dioxide for sequestration purposes.


GSI's In-Situ Gasification Process

Unlike traditional extraction methods, our proprietary technology is economical, environmentally friendly, and self-sustaining. The GSI process is a conceptually simple system:

  • Gases are heated in an above ground system.

  • While carefully controlling oxygen content, the heated gases are delivered into the bottom of the production well using an inlet conduit, thereby heating the entire cross section of rock and oil shale layers.

  • The continuous heating of rock and oil shale layer creates a hydrocarbon rich mix of hot gases that flow into an effluent conduit that is anchored around the opening of the production well.

  • These effluent gases are then condensed to separate Medium and Light Crude Oil (in liquid phase) and associated lighter gases such as Hydrogen, Menthane, Propane and Butane.

The process achieves a controlled and relatively quick production of partially refined and readily marketable products.
