Williston Basin · Non-Operating Working Interests

Discipline in
American Energy.

We view the Williston Basin not as a frontier, but as a factory floor. By applying mathematical precision to third-generation heritage, we strip the speculation out of extraction.

The Philosophy
We don't buy land; we buy math. SISU was founded to resolve a contradiction in the energy sector: the gap between generational intuition and data-driven precision.

Every position we take is grounded in demonstrated production history from offsetting wellbores, established decline curve models, and mechanical integrity.

We do not underwrite exploration. We underwrite extraction efficiency in proven geologic windows. This is not inherited instinct. It is earned precision.

The Approach
Three strict mandates define every capital allocation we make. If a project does not meet all three criteria, we do not participate.
01
Tier-One Geology

We operate exclusively within the Williston Basin. By targeting established formations with robust offsetting production history, we isolate our focus purely on extraction efficiency.

Proven Formations
02
Premier Operators

We do not operate the rigs. We aggregate capital to partner exclusively with proven, well-capitalized operators who hold a documented track record of safe, precise execution.

Vetted Execution
03
Disciplined Underwriting

Geology and execution are meaningless without the right math. We model every opportunity against strict decline curves and multiple commodity price scenarios to ensure asymmetric upside.

Stress-Tested Returns
"The Williston Basin is no longer a frontier; it is a factory. Success here requires treating extraction as a disciplined, mathematical process rather than a speculative venture."
Heritage & Mathematics

As a third-generation member of an oil and gas family, Westin Bye understood early that the days of wildcatting were over. Bringing a formal background in mechanical engineering to the family legacy, he founded SISU to approach the basin strictly as a factory floor. The strategy is simple: pair deep, generational access with rigorous, uncompromising structural analysis.

Technical Diligence

Underwriting
The Asset.

For sophisticated partners, the high-level summary is not enough. We provide full transparency into the mechanical, mathematical, and structural frameworks that underpin every capital decision.

Mechanical
Horizontal Architecture
Understanding the modern multi-mile lateral wellbore, perforation clusters, and the hydraulic fracturing mechanics that define extraction efficiency in the Bakken and Three Forks formations.
Mathematical
Decline Curve Analysis
How we use Arps hyperbolic decline modeling against historical production data to project yield, calculate EUR, and stress-test returns across multiple commodity price scenarios.
Structural
Capital Efficiency & Tax Structure
The precise mechanics of Intangible Drilling Cost (IDC) deductions—which often shelter a significant percentage of invested capital in year one—and how the percentage depletion allowance supports tax-advantaged cash flow.
The SISU Standard

Institutional
Transparency.

Sophisticated investors require more than access to premium assets. They require premium execution. SISU is built to provide a frictionless back-office experience from first conversation to ongoing distribution.

Clean Tax Reporting
Accurate, timely delivery of Schedule K-1s, allowing your CPA to seamlessly integrate your Intangible Drilling Cost deductions and depletion allowances.
Production Data
No black boxes. Partners receive clear, regular reporting on wellbore performance, production volumes, and revenue distributions directly from the operator.
Direct Alignment
We invest our own capital alongside yours in every project. Our operational structure ensures that our success is mathematically tethered to yours.
Direct Access
By aggregating capital, we secure non-operating working interests in premier assets typically reserved for institutional funds.
