SHELL | RED LEAF RESOURCES | AMERICAN SHALE OIL | OIL SHALE EXPLORATION COMPANY | OTHERS

According to the Unconventional Fuels Task Force report from September 20091, several companies are actively engaged in various aspects of oil shale technology development in Colorado, Utah, and Wyoming. Go here for the full version of this report.

In addition, according to their report from June 20092, a number of public agencies, laboratories, and universities are actively involved in oil shale research. Go here for the full version of this report.

In the sections below, we offer a general overview of some of the major companies doing research into Colorado, Utah and Wyoming oil shale.

Freeze Wall Test


Shell Exploration and Production - www.shell.com/us/mahogany

 

Shell owns three (3) of the 160-acre Research, Demonstration, and Development (RD&D) leases located on BLM lands. Shell is working on an In Situ Conversion Process, where electric heaters are drilled into the oil shale resource. These heaters gradually heat the rock to between 650- and 750-degrees. At this temperature, the hydrocarbons in the oil shale are released. Once released, traditional methods are used to bring the resource to the surface. The Shell In Situ Conversion Process produces 2/3 liquid hydrocarbons and 1/3 gas hydrocarbons. In one pilot program, a 30’-by-40’ area produced 1,700 barrels of high quality light crude oil and the associated gas.

Currently, Shell is conducting their “freeze wall” test. The freeze wall is an environmental study to show that groundwater can be kept out of the production area. Holes are drilled around the production area and a closed-loop pipe system is inserted. Refrigerant is piped through the system, freezing area groundwater and creating an impermeable barrier. Once the barrier is completed, the production area is dewatered and heated. The resource is extracted and groundwater is protected.

At this time, Shell has completed the Freeze Wall.  They are currently conducting tests on the Freeze Wall's effectiveness.

Red Leaf Resources, Inc. – www.ecoshale.com

 

Red Leaf Resources, In.c Red Leaf Resources, Inc. is perfecting their new “EcoShale” process. Headquartered in Salt Lake City, Red Leaf has conducted a small pilot program on Utah State Lands south of the city of Vernal. The EcoShale technology is particularly exciting, because no process water is used and no groundwater is impacted. In addition, the process is energy efficient, low in carbon-dioxide emissions, and lends itself to quick and effective reclamation.

In the EcoShale process, the topsoil in a location is removed and a bentonite environmental protection layer is constructed in the opening. Raw oil shale ore is trucked to the location and heated with natural gas. Once heated, the hydrocarbons are released, collected and refined. Once all the hydrocarbons have been removed, the spent shale is left in place. The topsoil is restored and grasses and plants quickly reestablish themselves for wildlife or rangeland uses.  One item of particular note is that Red Leaf's technology could be economically viable on a small scale.

At the 2010 Colorado School of Mines Oil Shale Symposium, Red Leaf announced that their process will use less than one barrel of water per barrel of oil.  In addition, they anticipate small-scale commercial production within the next 2-3 years.  Currently, Red Leaf is planning a larger pilot project.

American Shale Oil, LLC – www.amso.net

 

American Shale Oil, LLC (AMSO) holds one of the 160-acre RD&D leases in Colorado. AMSO is a 50/50 partnership between the French energy company, Total, and IDT Corporation. The AMSO concept is to use the CCRTM (Condensation, Convection, and Reflux) Process, whereby directionally drilled, parallel heating and production wells will be drilled into the resource. There, the resource is heated, releasing the hydrocarbons. The main benefit of the AMSO program is that a minimum of surface is disturbed as the wells are drilled in a 200-foot wide corridor as opposed to directly over the resource. AMSO is currently working with the BLM on their pilot test program and characterizing their resource.

AMSO is targeting a deeper oil shale formation (ilitic) that is below the area's water tables.  This could reduce the need for groundwater mitigation.  Right now, they are looking to conduct a pilot test on their R,D,&D lease in late 2010 or early 2011.

White River Oil Shale Mine

Oil Shale Exploration Company – www.oilshaleexplorationcompany.com

In March 2011, it was announced that Enefit (Eesti Energia) of Estonia had acquired Oil Shale Exploration Company (OSEC).  Enefit is a World leader in oil shale technology as Estonia has been utilizing oil shale for almost a century.  Enefit plans to import their technology to America.  The project is on a single BLM RD&D lease in Utah.

From the OSEC website:  "Enefit looks forward to continuing the work started by OSEC, with the aim of developing a modern commercial shale oil industry in Utah utilizing the Enefit technology. We envision this facility as not only being a leader in its field, but also creating long term stable jobs and economic benefits for the local community, the state, and the federal government.  Eesti Energia/Enefit is recognized throughout the world as the leader in oil shale development."
