eSteam’s downhole steam generator is a novel, disruptive and game-changing technology for heavy oil and oil sands production
The resources in Canada and the USA are readily accessible to oil companies, and the political and economic environments are stable. Heavy oil can be profitably produced with today’s higher market price. In Canada, the in-ground in-situ process involves injecting surface steam into horizontal wellbores. In particular, a technique known as Steam Assisted Gravity Drainage (SAGD) is rapidly growing.
Heavy oil resources are found in the United States, Canada, Venezuela, Russia, China, Oman, Brazil, Mexico, Columbia, Ecuador, Madagascar, Trinidad and other parts of the world including offshore.
eSteam™ is superior to conventional surface steam injection
Heavy Oil Background
Heavy oil is a dense, viscous crude oil that has an API gravity between 10 and 20 degrees.
Most heavy oil has a high viscosity and does not flow easily in the reservoir without heat.
Currently heavy oil production in the United States is in decline.
Heavy Oil Resources in the United States and Canada
The U.S. heavy oil resource approaches 100 billion barrels of original oil in-place.
Heavy oil is concentrated in 248 large reservoirs holding over 80 billion barrels of oil primarily located in California, Alaska and Wyoming.
Canada has the 2nd largest oil reserves in the world with about 1.7 trillion barrels of heavy oil and oil sands.
Heavy Oil Economics
Application of thermal recovery processes in heavy oil reservoirs depends on the capital cost per barrel of steam.
Oil price volatility is a significant deterrent to heavy oil projects, particularly with smaller independent producers.
Expanded development is resource constrained – capital, people, investment, and “know how”.
The economics of heavy oil production in California and Canada are well known for existing surface steam technologies. A disruptive technology such as eSteam™ could change the entire economic picture.
Conventional Surface Steam Technology
Most heavy oil recovery is by surface steam injection and in-situ production such as SAGD in horizontal wellbores.
Surface steam has been applied to produce heavy oil in shallow (less than 2,500 ft.) reservoirs, mostly in California, Canada and Venezuela.
Efficient thermal EOR technology such as eSteam™ could enable nearly two-thirds of the resource in-place to be recoverable from favorable shallow heavy oil fields and deeper onshore and offshore heavy oil reservoirs at or below 2,500 ft.
Additional U.S. heavy oil production of at least 500,000 barrels per day is possible with new technologies like eSteam™.
