Competent Person’s Report (cpr)

Naphtho provides independent reserves & resources audits for stock market listings and associated valuations, and for internal company management use.

We have undertaken CPRs for oil and gas assets in Europe, Africa, Central Asia and the Far East.

Services also include site inspections and documentation prepared to AIM / TSX guidelines.

Reserves Audits

Naphtho conducts Independent Audits of assets and portfolios. We will collate the necessary data and, utilising operator development plans, create production forecasts and profiles. All the stages required for asset valuation can be done in-house.

Naphtho is able to conduct Independent Audits of assets and portfolios to SPE-PRMS, NPD, COGEH and SEC standards.

Independent Reporting

Naphtho provides an expert opinion on third party reserves reports, information memoranda and operator development plans for interested parties, including banks and lending institutions.


Naphtho is able to conduct an in-depth economic analysis of an asset and, if required, build detailed fiscal models. Once production profiles are generated, an economic analysis is required in order to determine a production cut-off and permit an asset valuation.
