We review the technical basis of upstream oil and gas assets to support acquisitions, divestments, farm-ins, and investment decisions. Our assessment tests reservoir, production, well, facilities, cost, and schedule assumptions and identifies material risks, opportunities, and unresolved data gaps.
We examine the evidence behind an asset's technical assumptions and assess how uncertainty, operating constraints, and future obligations could affect production, expenditure, and project value. The review is tailored to the asset, transaction objectives, and available information.
Review the geological and reservoir basis of reported volumes, recovery assumptions, and resource classification to assess the credibility of the asset's recoverable potential.
Test forecast assumptions against production history, pressure response, well tests, and operating constraints to assess whether expected production can be delivered and sustained.
Assess whether processing, gathering, and export systems can accommodate the production forecast, and review documented equipment condition, reliability, and remaining service life.
Challenge the proposed development or redevelopment plan, including well delivery, facilities scope, expenditure estimates, and the dependencies that control the production start date.
Screen documented health, safety, and environmental issues and assess the technical basis of abandonment and site-restoration provisions that may affect future expenditure or operations.
Translate technical findings into inputs for economic evaluation and transaction discussions, identifying material downside exposure and opportunities that require further validation.
We agree the decision to be supported, review the available evidence, challenge material assumptions, and consolidate findings into a technical assessment with clear actions and limitations.
Scope and review depth agreed for each assignment
Define asset boundaries, transaction objectives, the evaluation date, materiality, and reporting requirements.
Check data completeness, versions, and consistency. Record missing information and request operator clarification.
Review models, forecasts, wells, and facilities. Use management interviews and site visits where included in the scope.
Assess material downside and upside drivers and quantify production, cost, or schedule impacts where data supports it.
Present evidence, findings, limitations, mitigation actions, and technical conditions requiring further resolution.
Traceable documents, reconciled data, and clearly stated uncertainties.
Issues that could change production, expenditure, timing, or asset value.
Prioritized mitigation, further work, and technical decision conditions.
The data request is matched to the asset's maturity and the agreed scope. An early review identifies information gaps that may limit conclusions or require additional investigation.
Deliverables connect technical findings to the decision you need to make. Each output states its evidence base, key assumptions, and unresolved issues so the review can be used alongside commercial and financial analysis.
An executive summary and discipline findings covering the asset, reviewed evidence, technical assumptions, limitations, and conclusions.
A prioritized record of material issues, potential production, cost or schedule effects, supporting evidence, and mitigation options.
Reviewed production profiles, cost and schedule assumptions, abandonment inputs, and sensitivity cases for economic evaluation, as included in the agreed scope.
Open questions, additional data requests, recommended studies, and technical conditions to address before or after the transaction.
Scope of work: The assessment depth, access to operator data, interviews, and site visits are agreed at the outset. Formal reserves certification, physical inspection or testing, and specialist legal, tax, or environmental studies are defined as separate workstreams when required.
