OGEL Products & Services

A subscription to OGEL includes A) access to the journal; B) OGELFORUM membership; and C) the Legal & Regulatory database. Below follows an explanation of the different OGEL services & Products.

A) OGEL Journal (ISSN 1875-418X)

Oil, Gas & Energy Law (OGEL, ISSN 1875-418X) is a peer-reviewed academic journal covering recent developments in the area of oil-gas-energy law, regulation, treaties, judicial and arbitral cases, voluntary guidelines, tax and contracting, including the oil-gas-energy geopolitics. It publishes short comments, scholarly articles, opinion pieces, and book reviews. The journal was established in 2003 and is published by MARIS BV from the Netherlands. Since the start it has gained popularity with a large number of (international) energy companies, governmental organisations, law firms (mainly those with a claim to special competence in international oil, gas and energy regulation), international agencies, academic and think-tank institutions in the field of energy policy and various NGOs.

Open to all to read and to contribute

OGEL has become the hub of a global professional and academic network. We therefore invite all those with an oil-gas-energy law and regulation interest to contribute. In addition to full length articles, we are looking for short comments on recent developments of broad interest. We would like where possible such comments to be backed-up by provision of in-depth notes and articles and primary legal and regulatory materials. Please contact us if you want to participate in this global network: we are ready to publish contributions with name, photo, and brief biographical description - but we will also accept anonymous ones.

Fully searchable archive

The OGEL journal started in 2003. As a result, there is an extensive database with over 2000 articles available. This fully searchable archive will help you with your research and can provide valuable background information and insights. The full archive is only available for premium subscribers.

To summarise:


The OGELFORUM mailinglist or listserv offers a unique platform for discussion, sharing of insights and intelligence of relevant issues related in a significant way to oil, gas and energy issues: Policy, legislation, contracting, security strategy, climate change related to energy.

OGELFORUM brings together most of the world's experienced professionals in the field of oil, gas and energy law, regulation and policy. OGELFORUM members are now the most up-to-date informed professionals in these fields. A fully searchable archive of OGELFORUM discussions is available to all OGEL readers.

You can learn more about OGELFORUM here.

C) OGEL Legal & Regulatory Materials

A valuable asset of your OGEL subscription is the database of Legal and Regulatory Materials, a growing collection of (energy) laws, treaties, agreements, awards and other primary materials relating to the Oil, Gas and Energy sector.

Different from existing services, this "OGEL knowledge bank" focuses in particular on the inclusion of authoritative "soft" regulatory materials - voluntary codes, guidelines, standards, resolutions and declarations. Both the impact of the NGO "civil society", the corporate governance and the professional communities are reflected in the "soft" regulation database.

Be sure to check out our special arrangement for a combined OGEL/TDM subscription.
