Oil & Gas Lender Model Review
Executive Summary
Key Takeaways
- ✓ A lender reviewing an oil and gas financial model applies sector-specific checks, independent borrowing base replication, reserve report currency, and hedging compliance, beyond the general lender model review discipline.
- ✓ Independent borrowing base replication means the lender's own team, not only the borrower's model, recalculates the available borrowing base under the facility's specific methodology.
- ✓ Reserve report currency confirms the reserve report underlying the model is sufficiently recent and has not been superseded by a later technical update the model has not yet incorporated.
- ✓ Hedging programme compliance confirms any hedge structure required as a condition of the facility is actually in place and correctly reflected in the model's realized price assumptions.
Objective¶
This guide sets out how a lender reviews an oil and gas financial model, within Oil & Gas Financial Modelling, extending the Knowledge Centre's general Lender Model Review Checklist.
Independent Borrowing Base Replication¶
A lender's review should independently replicate the reserve-based lending borrowing base calculation using the facility's own methodology, rather than relying solely on the borrower's model output, consistent with the replication testing addressed in Oil & Gas Model Validation. This independent recalculation is the specific step that gives the lender assurance the facility's mechanics have actually been applied correctly.
Reserve Report Currency¶
The review should confirm the reserve report underlying the borrower's model is sufficiently recent and has not been superseded by a later technical update not yet reflected in the model, since a stale reserve report can materially misstate the current borrowing base a redetermination should be calculated against.
Hedging Programme Compliance¶
Where the facility requires a hedging programme covering a portion of forecast production, the review should confirm the actual hedge structure in place is correctly reflected in the model's realized price assumptions, rather than the model assuming unhedged spot exposure inconsistent with the facility's actual requirements.
Common Review Gaps¶
- Accepting the borrower's stated borrowing base without an independent recalculation using the facility's own methodology.
- Failing to confirm the reserve report underlying the model is current, rather than superseded by a later technical update.
- Reviewing realized price assumptions without confirming they reflect the actual hedge structure required as a condition of the facility.

Frequently Asked Questions
How does an oil and gas lender model review differ from a general lender model review?
It adds sector-specific checks, independent borrowing base replication, reserve report currency confirmation, and hedging programme compliance, on top of the general discipline covered in the Lender Model Review Checklist.
Why does the lender independently replicate the borrowing base rather than relying on the borrower's model?
Because the borrowing base calculation directly determines available credit under the facility, and relying solely on the borrower's own model output would not provide the lender independent assurance that the facility's specific methodology has been applied correctly.
What does reserve report currency confirm?
That the reserve report underlying the borrower's model is sufficiently recent and has not been superseded by a later technical update not yet reflected in the model, since a stale reserve report can materially misstate the current borrowing base.
What does hedging programme compliance review check?
That any hedge structure required as a condition of the facility is actually in place and correctly reflected in the model's realized price assumptions, rather than the model assuming an unhedged spot price exposure inconsistent with the facility's actual requirements.

Oil & Gas Financial Modelling
Oil and gas financial modelling is the practice of building financial models across the four structurally distinct segments of the hydrocarbon value chain, upstream exploration and production, midstream transport and processing, downstream refining and petrochemicals, and LNG, each governed by different revenue mechanics, contract structures and risk drivers. This page is the hub for the Knowledge Centre's oil and gas financial modelling content: industry structure and segment definitions, the financial KPIs the sector is measured against, the investment lifecycle from exploration through decommissioning, and how this domain builds toward asset and project-level models, commercial and investment analysis, and governance and assurance practice as it expands.
Lender Model Review Checklist
This checklist covers the checks a lender, credit committee, or independent reviewer should apply to a borrower's financial model as part of credit approval or financial close. It focuses on covenant calculation integrity, debt sculpting mechanics, cash waterfall priority, and circularity resolution specific to debt-financed models. It is intended for banks, credit teams, and advisors conducting lender-side model review ahead of a financing decision.
Reserve-Based Lending
Reserve-based lending (RBL) is the dominant financing structure for upstream oil and gas assets, tying the available borrowing base to the discounted value of proved reserves under a bank-defined price deck, redetermined periodically, typically semi-annually, against updated reserve and price estimates. The financial model supporting an RBL facility must replicate the lender's specific borrowing base methodology precisely, since an approximated version will not match the actual facility mechanics.
Oil & Gas Model Validation
Validating an oil and gas financial model requires procedures beyond general model validation practice: reconciling the model's decline and reserve assumptions against the current reserve engineering report, independently replicating any reserve-based lending borrowing base calculation, and verifying fiscal regime waterfall mechanics against the actual contract terms. This guide sets out these procedures as a step-by-step validation methodology, extending the general model validation discipline with the sector-specific checks this domain requires.
