OERN Forum Archive

If you got here from the old link, It means that you were looking for a topic or section of the OERN historical forum, which used to work on the domain oern.ru. Old addresses in the format /index.php/topic,... и /index.php/board,... are now redirected to this page so that citations, bookmarks and external mentions are not lost.

Why this OERN forum archive was created

The forum was a platform for professional discussions on subsoil use and expert practice. After the site was relaunched, the former structure of the forum changed, and direct links from old publications began to lead to non-existent pages (404). This archive closes the gap: it helps you understand what you were looking for and quickly find relevant materials on the current site.

How to find a topic using an old link

1) You have an old link of the form `/index.php/topic,...`

Copy the old URL in its entirety (even if it's already redirected here).
Pull an identifier from it: e.g., from /index.php/topic,31.0.html - number 31.
Do a Google/Yandex search on the query: site:oern.ru 31 "topic" Or add the keywords from the topic title (if you remember).

2) You have an old link of the form `/index.php/board,...`

This is a link to a forum section/category, not a specific thread.
Take the partition number (e.g., from /index.php/board,1.0.html - number 1).
Search on demand: site:oern.ru board 1 + keywords (oil, gas, TPI, reporting, audit, classification, etc.).

3) You don't have a link, you only have keywords

Use site search and/or external search. Practical query template:

site:oern.ru "OERN" + (your phrase)
site:oern.ru subsoil use expertise expertise reserves resources
site:oern.ru CRIRSCO NAEN Code

Where old forum discussions most often “led” to

Historical links from the forum are usually from the following areas (use these words when searching):

Public reporting of reserves and resources, disclosure standards and practices;
reserves/resource classifications, methodology and terminology;
expert opinions, independent expertise, data quality requirements;
oil and gas, TPI, hydrogeology, geological exploration, project appraisal;
regulation, compliance, interaction with professional and state institutions;
education, expert qualifications, professional ethics.

Useful sections of the current site

If you are not here for “discussion” but for official materials and structured information, start here:

Important: what this means for “old” links

Why did I end up on one page instead of a topic?

Because the historical forum had thousands of unique URLs, and your link leads to the address format of the old platform. At the first stage, it was more correct to return users to a single “entry point” and then restore the most significant destinations and point pages based on statistics.

Will specific topics be reinstated?

Only those for which there is real demand: conversions, external links, citations. If a specific topic is critical for you, prepare the minimum: an old URL, an approximate title and 2-3 keywords. This dramatically speeds up spot recovery or correct comparison with actual material.

Recommendation for those who cite materials

If you administer a site/document that has an old link to the OERN forum, update it to the current page on the current site (or use this archive page as a neutral entry point). That way you won't link to a 404 and you won't lose readers.
