Exploration data

The OGA is committed to improving access to quality data to revitalise exploration of oil and gas across the UK Continental Shelf (UKCS). Over the past few years numerous licence round data packages, including the recent 32nd licence round, and other geoscientific data packages have been released. There is over 400GB of exploration data now freely available on the OGA’s open data site.

All data can be accessed through the UK National Data Repository (NDR) and the OGA Open Data site

The table below is a summary of all the exploration data, as of January 2020, that is openly available on the OGA’s Open Data site.

Initiative Link Area Provider Abstract
21CXRM BGS MNSH Final MNSH BGS Study of the Carboniferous and Devonian petroleum systems focused over and around the Mid North Sea High. The project delivery includes seismic, well and gravity interpretations along with burial/uplift/maturity modelling, source rock geochemistry studies and palaeographic reconstructions to inform the location of prospective Carboniferous and Devonian plays. Onshore data and knowledge has been incorporated.
21CXRM BGS Irish Sea Final Irish Sea BGS Study of the Carboniferous play focused on the Irish Sea area. The project delivery includes seismic, well and gravity interpretations along with burial/uplift/maturity modelling, source rock geochemistry studies and palaeographic reconstructions to inform the location of prospective Carboniferous and Devonian plays. Onshore data and knowledge has been incorporated.
21CXRM BGS 21CXRM Paleozoic Project UKCS BGS Study of the Carboniferous and Devonian petroleum systems. The project delivery includes seismic, well and gravity interpretations along with burial/uplift/maturity modelling, source rock geochemistry studies and palaeographic reconstructions to inform the location of prospective Carboniferous and Devonian plays. Onshore data and knowledge has been incorporated.
21CXRM BGS Orcadian Final UKCS BGS Study of the Carboniferous and Devonian petroleum systems focused over and around the Orcadian Basin/East Shetland Platform.
The project delivery includes seismic, well and gravity interpretations along with burial/uplift/maturity modelling, source rock geochemistry studies and palaeographic reconstructions to inform the location of prospective Carboniferous and Devonian plays. Onshore data and knowledge has been incorporated.
21CXRM Source Rock Potential - ESP ESP IGI Evaluation of the source rock potential of the East Shetland Platform including an interpretation report, a geochemical database, 1-D modelling input data and results and a comprehensive literature database.
21CXRM Post Well Analysis CNS OGA A post well analysis of exploration and appraisal wells drilled during 2003-2013 in the Moray Firth and the UK central North Sea has been carried out. Wells fall into three categories: dry, technical success, and commercial success. The project focused on the dry wells and the technical but not commercial successes. This was a deliberate move to ensure that we captured key learnings that could be transferred across industry.

31st Licence Round Durham University Post Doctoral Research Project - New Appraisal of the Western Approaches Basin SWA Durham University This project was focused on the SW Approaches area. The deliverables include a review of the chronostratigraphy of the SW Approaches and surrounding basins, an evaluation of the impact of Variscan deformation on the hydrocarbon potential of the area, an assessment of the reservoir quality of the Triassic and Lower Cretaceous intervals and the provision of reservoir and source rock distribution maps.
31st Licence Round Hypo-Lias: Hydrocarbon potential of the Lias UKCS TNO The original Phase 1 Hypo-Lias report was commissioned by a small group of industry sponsors and remains confidential to that group until 2019. The initial phase of the project was primarily focused around data from Norway and the Netherlands with some UK onshore analogue information. The OGA participated in Phase 1 of the Hypo-Lias project as a late entrant on the understanding that a subsequent UK Addendum could be made available for publication on completion. This delivery represents the work carried out as part of that addendum.

32nd Licence Round Prospects and Leads from Relinquishment Reports UKCS OGA A spatial database of mapped exploration leads and prospects is being made available. This additional resource has been compiled from information contained in relinquishment reports that have been provided to the OGA since 2004. This product enables the location of mapped opportunities to be viewed spatially and also filtered according to reservoir age. The database also provides a link to the published relinquishment reports so that the reports can be easily accessed via this spatial view.
32nd Licence Round Seeps Database UKCS OGA The OGA has purchased CGG’s NPA Satellite Mapping (NPA) database for the UKCS for publication. The UK database is composed of 983 individually interpreted satellite images, which form between a 10x and 20x temporal coverage, with 20x coverage for the majority of the North Sea. The NPA methodology uses multiple temporal snapshots in order to reduce interpretation ambiguities, account for the episodic nature of seepage and provides an interpretation of temporally repeating oil slick sites.
32nd Licence Round Structural and Tectonic Elements Database UKCS Getech This structural and tectonics database has been purchased from Getech by the OGA for publication. It is based on mapping using gravity and magnetic datasets, remote sensing data, geology maps, publicly available seismic data and literature. Structures are mapped at 1:1m scale, and an extensive number of attributes explain the data used in mapping, kinematics and confidence in the interpretation of the structure. Each structural element also has a detailed activation history within the attribution, describing periods of activity or inactivity and the kinematics through time based on direct data and/or Getech’s tectonic model for the area. 
32nd Licence Round AFTA UKCS Regional Reports UKCS Geotrack In collaboration with Geotrack International, the OGA is releasing the full catalogue of AFTA regional reports produced by Geotrack for the UKCS. This regional library represents a valuable source of data that can be used to aid the understanding of basin evolution and the impact on active petroleum systems. The reports include data from approximately 170 wells from the main basins of the UKCS plus additional supporting data from relevant outcrops.
32nd Licence Round CGG Digital Well Logs UKCS CGG The OGA has purchased digital well data from CGG for an additional 2235 E&A wells. Where available, the OGA has purchased joined digital well logs, deviation data and checkshot data for these additional wells.

The majority of the entries in the database represent legacy geochemical data collated from CDA (now NDR), the core/cuttings accessions database and other geochemical data. The database also includes new fluid analyses that have been carried out to fill data gaps. This database represents the largest publicly available geochemical database ever compiled for the UKCS. In addition shallow seismic interpretation, petrophysical TOC evaluations for potential source intervals in the Devonian and Middle Jurassic and a set of integrated regional depth maps are also released.
32nd Licence Round Octek-uk UKCS Badley Geoscience In collaboration with Badley Geoscience, the OGA is making available Badley’s OCTek-UK products. OCTek-UK provides maps and grids of crustal structure for the UK and adjacent areas, produced by application of the OCTek gravity inversion technique.
