UK Onshore Geophysical Library, c/o Lynx Information Systems Ltd, 84 Coombe Road, New Malden, Surrey, KT3 4QS.
The contact telephone number 0208 780 2634 and all contact email addresses will remain unchanged.
We apologise for the inconvenience that the relocation of our office caused resulting in the website and interactive map being offline during this period, but we are now fully operational following the move.
The 14th Onshore Licence Applications have been released by the Oil & Gas Authority and can now be accessed via the UKOGL website.
Applications can be searched and downloaded either geographically via the ‘Catch all reports’ icon on the interactive map or via a text based search using the ‘Industry Activity Reports’ link on the UKOGL home page.
Dr Malcolm Butler, Chair of UKOGL since its foundation in 1994 and joint
Director of Beneath Britain since it was established in 2018, has been
appointed an Officer of the Order of the British Empire (OBE) by the
Queen in the 2021 New Year’s Honours List for services to Education,
Research and Development.
UKOGL have recently completed a project to improve the coverage of 2D SEGY format migrated seismic data available in UKOGL. Migrated hardcopy sections for 219 lines have been scanned and vectorised to SEGY and are now available for release. The lines were selected to ‘infill’ areas that previously lacked migrated SEGY data coverage.
The image below displays the 219 lines selected over England overlaid on top of the complete 2D onshore seismic coverage available through UKOGL.
The image below displays the new 2D data set (red lines) that improves and complements the comprehensive 2D migrated coverage (purple lines) already available in UKOGL; infilling areas that previously had limited SEGY format migrated data.
Please contact UKOGL for more information about the new update to the post stack SEGY archive or for any other questions that you may have about UKOGL.
The migrated hardcopy sections were scanned and vectorised by Lynx Information Systems, output to SEGY and are now ready for workstation loading.
Update: 10th August 2020 – The UK Onshore Geophysical Library office has now re-opened, but with a reduced level of office based staff. Contact can now be made with UKOGL by both phone and by email, via our general email address (email@example.com) or direct via the contact details here.
Well Layer Improvements and Two-Way Time Data Generation
UKOGL have improved the appearance and functionality of the
Well Layer displayed on the interactive map, the expanded selection options include
the ability to filter on the well category, wells that reach a certain depth
and wells that penetrate certain formations.
In addition, a new functionality has been embedded as an
option to generate estimated Two-Way Times (TWT) for wells that do not
currently have TWT data available through the site.
The well category display, search, filter and selection options
on the map can now be controlled via a single user selected ‘drop-down’ menu option,
which combines both the old “Well” layer and the old “Additional Selected
Boreholes” layer in to one layer that now removes the need to run the same query
twice across the two data sets.
All wells with TWT data can now be filtered on the display
via the menu to improve access to TWT information.
The UKOGL interactive web map now supports ‘on the fly’
generation of TWT data for wells that do not have TWT data currently available.
Using the mouse arrow select a well without TWT data then select the ‘DEPTHS’ – ‘Well Tops – View’ option to launch the well information page.
By selecting the ‘Two-Way Times’ option on the page a list
of ’near-by wells’ is generated that already have TWT data available. A buffer
range can be used to limit the search radius of the donor wells available to
The TWT data is generated by extrapolating the TWT depths from
the user selected well to the corresponding depth of the well that is currently
without TWT data. Data is generated ‘on the fly’ each time a donor well is
selected by the user.
The newly generated TWT data can be downloaded from the UKOGL site as a spreadsheet document. Values generated by the Two-Way Time extrapolation function are not retained by UKOGL but they can be regenerated by the user if required again at a later date.
While a great effort has been made by UKOGL to accurately generate TWT data from extrapolated well depths, use of the generated values is always at the users own discretion.
