In recent years, Norway has moved towards shorter confidentiality periods for seismic data, releasing geology reports earlier than expected. Seismic data providers and stakeholders should be aware that their data may no longer be protected by confidentiality – and of potential conflicts between their contractual confidentiality provisions and statutory disclosure requirements.
From 20 Years to 5 Years: Regulatory Evolution
In the early 1990s, regulations allowed many forms of seismic data to remain confidential for up to 20 years. The 1991 Petroleum Regulations established a tiered system: interpreted seismic data (such as geophysical analyses, reservoir interpretations) could be kept secret for 20 years; commercially marketed multi-client data for 10 years; and most other data (like raw field data from licensed areas) for significantly shorter periods (typically 2 to 5 years) (The development is briefly described in a presentation from Norwegian Offshore Directorate from 11. april 2024 on Reporting Requirements and Release of data, which can be found here).
By 2021, however, authorities signalled a move toward greater transparency. The Norwegian Petroleum Directorate ("NPD") began releasing certain reports much earlier than expected. In a push for openness, about 600 previously confidential “relinquishment reports” (detailed interpretations filed when production licences end) were made public on NPD’s Fact Pages. This surprised those that had commissioned for seismic interpretations assuming two decades of exclusivity. Regulators, however, were unequivocal: private agreements cannot override the mandatory disclosure rules.
On 1 January 2023, an amendment to Section 85 of the Petroleum Regulations cemented this trend toward shorter confidentiality and exclusivity: interpreted geophysical datasets now enjoy at most 5 years of confidentiality; and “other data” (essentially raw or non-interpreted data that are not commercially marketed) only 2 years. Additionally, if a production licence is relinquished, any interpreted data in the final status report must be released after just one year. Even commercially available seismic data (including multi-client surveys sold to third parties), which as a starting point remains protected for 10 years, can, when included in a relinquishment report, be disclosed at licence expiry. The only category exempt from these shortened timeframes are bona fide trade secrets, which remain confidential for up to 20 years. NPD may, in special cases, grant extensions or reductions of confidentiality on application, though never beyond 20 years.
Contract vs. Law: When Duties Conflict
Any contractual confidentiality clause must yield to legal obligations. If a contract were to stipulate, for example, that a seismic interpretation is to be kept confidential for 15 years, this provision is unenforceable considering that Section 85 of the Petroleum Regulations mandates disclosure after 5 years. Parties cannot contract out of the public-law reporting duty.
This means companies acquiring, processing, or licensing Norwegian seismic data should carefully review their confidentiality clauses. Older agreements (pre-2023) might contain confidentiality obligations that are inconsistent with current law.
Companies active in acquiring or using seismic data in Norway may want to update contract templates and strategies to reflect the new rules. Where existing contracts assumed longer confidentiality, renegotiation may be necessary, or at least to reach a mutual understanding of potential consequences to the parties. Overall, the direction is clear: data will emerge into the public domain sooner than before.
Interpreted Data
Another important consideration is the definition of “interpreted data” versus “other data.” The 2023 changes came alongside official guidelines clarifying these terms. The authorities now define "interpreted data" as products that are the result of a discretionary professional assessment, and which are of sufficient quality to form a basis for decisions in a production licence – explicitly excluding processed geophysical data and basic measurements from the definition of interpreted data (NPD has published a practical reporting guide, the so-called "Yellow Book". In it, the definitions connected to the different confidentiality windows are further defined and explained. The Yellow Book can be found here, guideline number 9). In practice, this means many deliverables that operators might informally call “interpretations” (e.g. processed seismic volumes or datasets with some level of enhancement) could be classed as “other data” with only a 2-year confidentiality window. It is a drastic reduction from 20 years' confidentiality in the 1991 regulations, and 5 years under the current regulation.
