Institutional-grade access to domestic oil & gas

Capitalizing on the structural undersupply of domestic and global energy.

The world still runs on oil & gas — and capital has retreated

For more than a decade, ESG mandates and the 2020 price shock have starved the upstream sector of capital. Institutional funding for new drilling has collapsed nearly 90% from its 2017 peak. Meanwhile, global oil demand continues to grow, existing fields decline 2–5% every year, and a supply gap of 7.1 million barrels per day is projected by 2030. The opportunity is structural — and the capital vacuum has opened the door for private investors.

For more than a decade, ESG mandates and the 2020 price shock have starved the upstream sector of capital. Institutional funding for new drilling has collapsed nearly 90% from its 2017 peak. Meanwhile, global oil demand continues to grow, existing fields decline 2–5% every year, and a supply gap of 7.1 million barrels per day is projected by 2030. The opportunity is structural — and the capital vacuum has opened the door for private investors.

The popular narrative says oil & gas is a sunset industry. The data tells a different story. The oil & gas industry generates $4.3 trillion in annual revenue and $3 billion in daily profit — making it the seventh largest industry in the world, larger than pharmaceuticals, automotive, or food production. And every industry ahead of it on that list is completely dependent on hydrocarbons.

Warren Buffett's Berkshire Hathaway has spent more than $400 million accumulating Occidental Petroleum stock, even as Wall Street panics about falling oil prices. The smart money sees what the headlines miss: a supply-constrained commodity with growing demand and a shrinking capital base willing to fund new production.

Aspen Energy's strategy is designed to capitalize on this dislocation. By acquiring non-operating working interests (NOWI) and overriding royalty interests (ORRI) in producing assets, the platform generates immediate cash flow from existing wells while securing the right to participate in new drilling on the same acreage — without taking on direct operational risk.

We focus on the lower 48 (no offshore exposure), partner with major operators in proven basins, target infill drilling rather than wildcat exploration, and employ partial price hedging to dampen commodity volatility. Add IDC, depletion, and depreciation tax advantages, and the result is a structurally advantaged path into one of the most important sectors in the global economy.

The Structural Energy Opportunity

Oil, natural gas, and coal still supply 83% of global energy demand. Renewables remain a small share of the mix, and the transition to alternatives is measured in decades, not years.
New exploration & development spending is down 55% since 2015. Existing fields decline 2–5% annually, requiring roughly 5 million barrels per day of new production every year just to stay flat.
Annual private equity funding into upstream oil & gas collapsed from $15.8B in 2015 to roughly $1.6B in 2023. The retreat of institutional capital has created an exceptional opportunity for private investors.
The Aspen Energy model targets producing wells for immediate cash flow, paired with proven undeveloped acreage for new drilling — generating quarterly distributions with significant upside potential.

The Aspen Energy model

Institutional discipline across every energy investment decision
We target assets with proven geology and production histories consistent with major operator standards.
Aspen co-invests alongside established operators, positioning alongside experienced teams who bear the operational and geological risk.
We underwrite conservatively and hedge price exposure so the investment thesis does not depend on commodity price assumptions.
Formation-level risk analysis is a primary screen, not a secondary one. We evaluate what is underground before we evaluate what is on paper.

Three tax benefits unique to oil & gas

For high-income earners and high-net-worth investors, the tax treatment is often a primary reason to allocate to oil & gas.

Intangible Drilling Costs (IDCs)

Depletion

Depreciation
