Liberating America's Stranded Super-Basin

The Alaska Gasline and LNG project is a large-scale, integrated gas treatment, pipeline, and LNG production system which will allow the vast, conventional, proven, stranded gas resource on Alaska’s North Slope to be brought to local markets in Alaska and to global LNG markets. Anchored by the Prudhoe Bay field – North America’s largest oil and gas field – and the Point Thomson reservoir, the project has a proven conventional gas source for the first 40 years of project life. Alaska’s North Slope is a “super basin” with additional undeveloped gas resource for at least 100 years of supply.

The project will be the only practical link between the vast resource of the Alaska North Slope super-basin and the growing global LNG markets. Alaska is the closest and most direct North American supply to Asia, providing the project with a sustainable competitive advantage.

All major permits have now been received, and the project is ready to move forward to completion.

The “prize” of the Alaska LNG project is the enormous, proven, conventional, producing, but stranded gas resource on Alaska’s North Slope. With 40 Tcf of developed gas resource at Prudhoe Bay - North America’s largest oil and gas filed- and adjacent Point Thomson, the project has supply certainty for decades, with over one hundred years of additional potential resource. The Prudhoe Bay complex currently produces over eight billion cubic feet of associated gas per day, which has to be reinjected back into the reservoir for lack of an outlet to market. Prudhoe Bay sits in the middle of one of the world’s largest oil and gas basins, deemed by the American Association of Petroleum Geologists (AAPG) and IHS Markit Ltd. as one of 25 global “Super Basins”.   Alaska’s North Slope is a hydrocarbon-rich, largely unexplored area; at 245,000 square kilometers, it is larger than most U.S. states.  The Alaska gasline and LNG project will be the means to liberate the stranded resource.

The Arctic Carbon Capture Plant will be at Prudhoe Bay near existing oil and gas infrastructure. The plant would be comprised of three process trains to remove CO2 and impurities from the natural gas that could flow from the Point Thomson and Prudhoe Bay reservoirs. Carbon dioxide would be removed, captured, and compressed for reinjection into the Prudhoe Bay reservoirs. The Alaska LNG facility will be the only such facility in North America to capture and sequester the CO2 directly at the supply source. Highlights about the gas treatment plant include:

· Average daily capacity of 3.5 billion cubic feet; maximum capacity of 3.9 billion cubic feet per day.

· Located on 200+ acres near existing Prudhoe Bay production.

· Gas cleaned (CO2 removed), dehydrated, and compressed.

The backbone of the project is an 800-mile, 42-inch diameter pipeline being built in a well-established corridor with road access the entire route. With a daily capacity of 3.3 billion cubic feet, multiple compressor stations along the pipeline will help carry natural gas from the North Slope to Southcentral Alaska. Multiple interconnection points along the pipeline will provide for in-state gas distribution.

The pipeline will be constructed using proven and safe technologies. The design will minimize impacts to the environment, as the majority of the pipeline will be buried.

With the pipeline will come a stable supply of natural gas for Alaskans, ensuring they have access to a long-term and affordable gas supply for home heating and industrial needs. This economic resource will also drive multiple industries for Alaska including refining, and other industrial developments throughout resource-rich Alaska. The pipeline will transport North Slope resources to Nikiski for export to international LNG markets, ensuring demand and spurring new exploration projects throughout the state.

Details include:

· 800-mile, 42-inch diameter natural gas pipeline

· Multiple interconnection points for in-state gas distribution

· Multiple compressor stations

· 2,075 psig (143 bar) operating pressure

· Average throughput of 3.1 billion cubic feet per day; maximum capacity of 3.3 billion cubic feet per day

The liquefaction facility, located in Nikiski, will process, store, and produce up to 20 million tons of LNG per year using the Propane Precooled Mixed Refrigerant (C3MR™) Process, an Air Products patented technology. The innovative and highly technical facility includes:

· Three LNG trains

· Two 240,000 cubic meter storage tanks

· Terminal facilities and marine services

· Two loading berths to accommodate LNG carriers up to 217,000 cubic meters (Q-Flex)

The United States became the world’s largest LNG producer in 2023. 

The LNG markets in Asia comprise 75 percent of global LNG demand.

Constraints at the Panama Canal creates an economic barrier for each of the U.S. LNG projects to serve Asia.  Transiting the Suez Canal and Straits of Hormuz pose risks for LNG ships, making other global LNG suppliers a riskier choice for reliable supply.

The Alaska LNG project will be America’s closest LNG supply to the major LNG markets in Asia. The proven conventional resource, short and direct route with no third nation transit or constriction point, and stable pricing provides a competitive advantage for Alaska LNG.
