Elk Petroleum

What Elk Petroleum does

Elk Petroleum is a privately held, upstream oil and gas operator focused on the development and production of long-lived reserves through enhanced oil recovery (EOR) at the Greater Aneth Field, located in the Paradox Basin across the Colorado/Utah border on Navajo Nation land. The company operates three contiguous units covering more than 45,000 acres (the Aneth Unit at 62% working interest, the McElmo Creek Unit at 68%, and the Ratherford Unit at 59%) under a corporate structure in which Elk Petroleum Aneth, LLC (the parent, majority-owned by AllianceBernstein-managed funds) owns Resolute Aneth, LLC (leaseholder) and Elk Operating Services, LLC (the field operator). Elk is majority-owned and controlled by funds and accounts managed by AllianceBernstein, a global institutional investment manager, and is co-owned in part with the Navajo Nation Oil & Gas Company, with field staff predominantly drawn from the Navajo Nation.

The company's core technology is CO2 Enhanced Oil Recovery combined with legacy waterflood secondary recovery and selective horizontal drilling. The McElmo Creek CO2 flood began in 1985, waterflood secondary recovery dates to 1961, and horizontal drilling and additional CO2 flooding were instituted in the 1990s, with CO2 injection now active across approximately 75% of the Aneth Unit after beginning in 2007. Field production exceeds 500 million barrels from an estimated 1.5 billion barrels of original oil in place, leaving roughly 35% of reserves undeveloped. Production is optimized through rod pumps and electric submersible pumps, and management has deep prior EOR experience, including 21 years on Chevron's Rangely CO2 flood (SVP Operations) and senior production/drillings roles at EP Energy in the Uinta Basin.

Elk generates revenue by selling crude oil produced from the Greater Aneth Field to refineries and petroleum purchasers in the Rocky Mountain region; pricing is commodity-based and not publicly disclosed at the company level. Its go-to-market is asset-acquisition driven: the Business Development team actively evaluates and pursues onshore U.S. acquisitions where Elk can act as operator, with no software product, subscription pricing, or non-oil revenue streams. The customer base is effectively a single-asset, single-commodity exposure, and economic value is delivered alongside community-employment and economic-benefit commitments to the Navajo Nation.

Core offering

Elk Petroleum develops and produces long-lived oil and gas reserves at the Greater Aneth Field in the Paradox Basin, operating three contiguous units (Aneth Unit, McElmo Creek Unit, Ratherford Unit) covering 45,000+ acres on Navajo Nation land. Its core activity is tertiary CO2 Enhanced Oil Recovery (EOR) supported by waterflood secondary recovery and horizontal drilling, with the company acting as operator and majority working-interest owner across all three units.

Product overview

Elk Petroleum is an oil and gas company that operates as a holding company structure with three principal entities: Elk Petroleum Aneth, LLC (the parent company owning wells and infrastructure), Resolute Aneth, LLC (holding record title to leases and rights-of-ways), and Elk Operating Services, LLC (the operator of the three field units). The company's core product is the Greater Aneth Field, comprising three contiguous operating units (Aneth Unit, McElmo Creek Unit, and Ratherford Unit) covering 45,000+ acres on Navajo Nation land. Operations center on CO2 Enhanced Oil Recovery techniques, with the field having produced over 500 million barrels of oil from an estimated 1.5 billion barrels of original oil in place, leaving approximately 35% of reserves undeveloped. Elk Petroleum operates all three units with working interests ranging from 59% to 68%.

Direct peers

• Denbury Resources: Denbury was the most pure-play U.S. CO2 EOR producer, operating tertiary recovery floods in the Gulf Coast and Rocky Mountain regions using owned CO2 reserves and pipelines — directly comparable in core EOR technology, business model, and asset profile to Elk's Greater Aneth operations.
• EP Energy: EP Energy operated mature Uinta Basin and Permian assets with EOR/secondary recovery programs, and several of Elk's senior leaders (VP Drilling, VP Production) held engineering and management roles at EP Energy. Overlap in basin (Uinta), recovery techniques, and leadership experience makes it a strong comparable.
• Merit Energy: Merit Energy is a privately held, niche-focused operator specializing in mature, long-life oil and gas properties with secondary and tertiary recovery — closely comparable to Elk in scale, asset type (mature fields, EOR), operating model, and private ownership.

Others

• Kinder Morgan: Kinder Morgan is the largest transporter and supplier of CO2 to U.S. EOR operators via its Bravo and other pipelines. It is a key enabler and ecosystem partner for CO2 EOR economics and a relevant comparable for understanding CO2 supply and EOR project infrastructure.

Broad incumbents

• Chevron: Chevron operates the Rangely CO2 EOR flood in Colorado, where Elk's SVP of Operations Jeff Roedell spent 21 years. Chevron's Rangely project is one of the longest-running large-scale CO2 floods and is the closest analog in scale, reservoir type, and technology.
• Occidental Petroleum: Occidental operates the Permian EOR program and large-scale CO2 floods (e.g., Denver Unit, Hobbs field) and is a global leader in CCUS via its 1PointFive business — directly comparable in CO2 EOR technology, with a broader asset base and capital scale than Elk.

Emerging players

• Earthstone Energy: Earthstone is a small/mid-cap independent E&P focused on the Permian and Bakken basins, acquiring and developing mature and unconventional assets. Comparable in scale, acquisition-driven growth model, and operational focus to Elk.
• Whiting Petroleum: Whiting is a small/mid-cap independent E&P with operations in the Williston Basin and Rocky Mountain region, applying EOR and waterflood techniques to mature fields. Comparable in scale, geography, and recovery techniques to Elk.
• Mach Natural Resources: Mach is a small/mid-cap independent E&P with operations across multiple basins, applying secondary and tertiary recovery techniques to mature assets. Comparable in scale, asset philosophy (mature field optimization), and private/PE-backed ownership profile.
• Hilcorp Energy: Hilcorp is a privately held operator known for acquiring mature, declining onshore fields and applying intensive workover and enhanced recovery techniques to extend field life — directly comparable in operating style, asset profile (mature fields), and private capital structure to Elk.
