Denali Petroleum and Gas is developing a major natural gas field located in the Susitna Valley, approximately 70 miles from Anchorage, on over 567,000 acres leased from Alaska’s Department of Natural Resources. Per a bankable appraisal done in May 2026 by the by the consulting unit of ASRC Energy Services, a wholly owned subsidiary of Arctic Slope Regional Corporation, the field is estimated to contain 59 Trillion Cubic Feet ("59 TCF") of natural gas resources. At full envisioned field development, this amount of natural gas should be sufficent to serve many customers for well more than a century. The Cook Inlet Gas IPS covers about 9,600,000 acres and comprises the Cook Inlet basin, Matanuska Valley, and Susitna Lowland. All Denali-leased property is located in the Susitna Lowland basin. The USGS Scientific Investigations Report 2012-1545 determined that “The Cook Inlet-Susitna region of south-central Alaska contains large quantities of gas-bearing coal of Tertiary age. The U.S. Geological Survey completed an assessment of undiscovered, technically recoverable coal-bed gas resources underlying the Cook Inlet-Susitna region in 2011, based on the total petroleum system (TPS) concept... The Cook Inlet Coal-Bed Gas TPS encompasses approximately 9,600,000 acres, comprising the Cook Inlet basin, Matanuska Valley, and Susitna Lowland. Wells were drilled in the Susitna Valley during the 1960s and 1980s, revealing a substantial presence of natural gas. However, these wells were abandoned because the operator focused on finding oil. Subsequent studies by both the U.S. Geological Survey and the Alaska Division of Geology & Geological Services further determined that the formations in the region, including the Susitna Basin, are hydrocarbon-bearing strata—geological formations within which gas reserves are commonly discovered.
The analysis of samples from the surrounding wells located in the area of Denali’s leases shows natural gas from the region to be of high quality, high heat value based on 98 to 99 percent Methane (C1) and no indication of sour gas (low sulfur and low CO2), making this gas "sweet" of very high value for local consumption and power, as well as export via LNG.
Gas produced from this field will be sold to regional Alaskan gas utilities and is expected to help address the current decline in locally available gas supplies. Wells will be drilled and managed by a firm with long experience in the Alaska energy industry, the Arctic Slope Regional Corporation.
Denali is dedicated to minimizing its ecological footprint, protecting biodiversity, and mitigating climate impacts throughout the lifecycle of our natural gas operations. Denali seeks to support a lower-carbon future for the globe by providing natural gas to support energy production, a cleaner-burning fossil fuel than oil and coal. In producing and de-livering natural gas, Denali is committed to operating in a manner that supports environmental stewardship and to meet-ing all governmental requirements and standards. Environmental stewardship is not just a policy; it's a fundamental val-ue embedded in every aspect of our operations, enabling us to deliver clean, reliable natural gas while protecting natural resources for generations to come. ____________________ KEY AREAS OF ENVIRONMENTAL COMMITMENT WATER MANAGEMENT • Use responsible water management strategies.• Recycle produced water, to minimize freshwater consumption. • Protect local water sources through best treatment technologies and stringent disposal practices. • Minimize water footprint through efficient operations and continuous improvement." METHANE EMISSIONS REDUCTION • "Monitorr methane emissions reduction via advanced leak detection and repair (LDAR) programs." • Use best technologies to minimize fugitive emissions from wellhead to burner tip." • Employ solutions like drone-based monitoring and satellite imaging to identify and address leaks. • Implementing 'green completions' to capture gas that would otherwise be flared or vented. LAND USE & BIODIVERSITY PROTECTION • Minimizing operational footprint through efficient site design, multi-well pads, and directional drilling. • Restore /reclaim disturbed lands to their natural state, promoting biodiversity and ecological health. OPERATING EXCELLENCE & REGULATORY COMPLIANCE • Adhere to and/or exceed applicable environmental regulations and industry best practices. • Maintain Environmental Management Systems to support environmental performance. • Promote a culture of environmental responsibility among all employees and contractors. • Conduct regular environmental audits and assessments to identify and address potential impacts. • Commit to transparent reporting of our environmental performance.
