Frequently Asked Questions

An oil and gas reserves audit is an independent technical review of previously prepared petroleum reserves estimates. It examines supporting evidence, estimation methods and classification decisions to assess whether reported reserves are reasonable and adequately documented. This Oil & Gas Reserves Auditing and Independent Verification training course develops the skills needed to conduct these reviews and communicate technical findings.

Reserves evaluation estimates recoverable petroleum quantities using geological, engineering and commercial information. Independent reserves verification reviews an existing evaluation to assess the reasonableness of its estimates and supporting assumptions. This training course focuses on examining estimates prepared by others, identifying evidence gaps and documenting verification conclusions.

You will learn to plan a petroleum reserves audit, assess technical evidence and prepare structured audit findings. This Oil & Gas Reserves Auditing and Independent Verification training course covers PRMS classification reviews, estimation assumptions and the assessment of material discrepancies. Participants also develop their ability to trace reported estimates to supporting data and communicate defensible independent verification conclusions.

Yes. The training course applies Petroleum Resources Management System (PRMS) definitions and classification principles to reserves auditing and independent verification. Participants examine reserves categorisation, project maturity and the evidence supporting commerciality. The emphasis is on assessing whether classification decisions are justified by the available technical and commercial documentation.

The training course reviews volumetric calculations, decline-curve analysis, material-balance estimates and reservoir simulation forecasts from an auditor’s perspective. Participants examine the suitability of methods, the reliability of inputs and the reasonableness of recovery assumptions. The reserves auditing training course also addresses deterministic and probabilistic approaches to uncertainty.

This Reserves Auditing and Independent Verification training course is suitable for reservoir engineers, reserves auditors and petroleum reserves evaluators responsible for reviewing reported estimates. It also benefits subsurface managers, technical assurance specialists and independent petroleum consultants. Petroleum regulators and national oil company review teams will find the content relevant to their oversight responsibilities. Familiarity with reserves estimation, reservoir engineering or upstream asset evaluation is recommended.

Yes. Participants review proved, probable and possible reserves classifications within the PRMS framework. The training course examines the technical evidence and uncertainty considerations supporting these classifications, alongside the project maturity and commerciality requirements for recognising reserves. Participants learn to identify classification decisions that require further evidence or clarification.

This Reserves Auditing training course develops a structured approach to comparing reported reserves estimates with supporting data, estimation assumptions and classification criteria. Participants examine inconsistencies in technical interpretations, production forecasts and documentation. They then assess the significance of findings in relation to the audit scope and intended use of the reserves information.

Participants learn to review geological interpretations, reservoir studies and reserves calculations used to support petroleum reserves estimates. The training course also examines production histories, forecasts, fluid properties and reservoir parameters. Development plans and economic assumptions are reviewed to assess commerciality, classification and the traceability of audit evidence.

Yes. Participants contribute to an illustrative independent reserves audit report using the course’s sample technical documentation. They consolidate verification findings, assess material discrepancies and document evidence gaps or scope limitations. This activity develops their ability to present structured observations, recommendations and technical conclusions.
