Any upstream company - private, public or state-owned - is welcome to apply for IOGP membership.

Membership is also open to any association – national, regional or international – that already has on its roster at least two IOGP members and is directly concerned with exploration and/or production.

Associate membership is open to companies, other corporate bodies and national institutions that provide oil- and/or gas-field services to companies that qualify for full IOGP membership.

Our Memorandum and Articles of Association and Regulations provide full criteria.

Upstream membership fee structure

Units of interest


Members pay one unit for each of the following areas in which they have an interest in operations:

  • Europe
  • Middle East
  • Africa
  • Asia & Australasia
  • North America
  • South America
  • Russia & Caspian Sea

The cost of each unit of account is £11,840 per annum.

Membership tiers

Members are categorized into four tiers of fees, based on the level of the company’s production, based on gross barrels of oil equivalent (BOE):

Tier Production level Multiplier
1 More than 2 million BOE/d 1.50
2 600,000 to 2 million BOE/d 1.25
3 200,000 to 600,000 BOE/d 1.10
4 All other and associations 1.00

The multiplier does not apply to the European Supplement.

Example: For a Member with an interest in operations in all seven regions and allocated the tier 3 multiplier, the annual fee becomes:

(7 x £11,840 x 1.10) = £91,168

European supplement for upstream members

In addition to the standard fee for upstream membership, for companies with interests in Europe, there is an annual EU supplement of €53,810 (Euros) to cover the cost of IOGP’s Brussels Office.

Associate membership fee structure

The Associate Membership fee is subject to a multiplier of 0.5, per region.

For an Associate Member operating in all seven regions, the formula would work our as:
7 x £11,840 x 0.5 = £41,440 p.a.

European supplement for associate members

In addition to the associate membership fee, for companies with interests in Europe, there is an annual EU supplement of €53,810 (Euros) to cover the cost of IOGP’s Brussels office. The multiplier also applies to this figure. For an Associate Member this works out as:

€53,810 x 0.5 = €26,905 p.a.
