New Academic Initiative

Monday March 12th sees the launch of the new UKOGL Academic Hub ‘Beneath Britain’ to be based at Oxford University.

This will not only service all future academic requests but will provide unique research opportunities to further our understanding of the subsurface UK with workstation access to the complete UKOGL seismic archive.

The Library is currently seeking to work in partnership with the BGS and other parties to be able to provide an enhanced offering incorporating borehole records and geological backdrops.

More details and full contacts will be posted shortly and during this transitional set up period the UKOGL team can be contacted as normal for any academic enquiries.

2016 OGA UK Onshore Seismic Data Download

The 2016 OGA UK onshore seismic data release packages are now available to be downloaded via the UKOGL Interactive Map website.

The UKOGL Interactive map provides immediate access to the onshore reprocessed data packages and the post stack 2D and 3D SEG-Y data can be viewed before downloading using iSeisview – An online seismic data viewer developed by Lynx Information Systems Ltd. that enables the user to interactively view the Post Stack SEG-Y in real-time.

Only the reprocessed 2D post stack SEG-Y and 3D data that forms part of the 2016 OGA data can be viewed in iSeisview.

The seismic viewer developed by Lynx enables SEG-Y data in 2D or 3D inline and crossline profiles to be displayed interactively in a web browser and allows the user to select display styles, zoom levels, horizontal and vertical scales and trace amplitudes of the SEG-Y data.

Access to the 2016 OGA onshore data packages via the UKOGL Interactive map does not require a login.

The freely available government funded reprocessed onshore data is comprised of UK onshore reprocessed 2D post stack SEG-Y data, SEG-Y gathers, navigation data and supporting processing reports located over three onshore areas of the UK:

  • Isle of Skye
  • Solway Firth
  • South Coast of England.

The original processed 3D Wytch-Farm-98 post stack SEG-Y data is also available as part of the South Coast data set with all inlines and crosslines available to be assessed interactively using iSeisview before downloading.

How to Access the Data

Access to the OGA Onshore data packages is via the contents sidebar on the UKOGL Interactive Map as indicated below.

The reprocessed 2D Post Stack SEG-Y data and 3D Post-Stack SEG-Y survey can be viewed immediately by selecting the “Live Seismic Viewer” option to assess the data using iSeisView or, by selecting the “View and Download Files” option a Virtual Data Room developed by Lynx will be launched for each area to easily access all onshore files that have been made available as part of the 2016 Government-Funded UK onshore reprocessed data packages.

Following line selection – Option to interactively view the available SEG-Y data or access and download the data

The “View and Download Files” option launches the Lynx Virtual Data Room: 2D lines can be selected and the SEG-Y data viewed interactively via iSeisview either by selecting each line from the “Map” or via a “2D Seismic Line List” view.

Virtual Data Room – The selection of a 2D line enables the SEG-Y data to viewed interactively using iSeisview

To view inlines or crosslines from the available 3D survey in iSeisview, ‘hover’ over and ‘click’ on the 3D survey and then use the left mouse button to select an inline or the right mouse button to select a crossline.

The left mouse button is used to select an inline to view via iSeisview from the 3D survey.

The right mouse button is used to select a crossline to view via iSeisview from the 3D survey.

EBCDIC header information, inlines and crosslines can also be selected using the options via the SEG-Y viewer.

To download the available data select the “Download Files” tab.  The data for each package can  be quickly and easily selected for download using the ‘tick’ boxes. Data for each area and line has been grouped and “pre-zipped” in to associated processed versions, SEG-Y gathers, reports, velocity files and navigation data files to streamline access to the data packages.

Select files and download via the “Download Files” tab.

The terms of the use of the data as supplied as part of the 2016 OGA data release packages can be found in: Oil and Gas Authority user Agreement.

The 2016 offshore data packages are available from download via the UKOilandGasData portal.

 

Prospex 2017

We will be exhibiting at the upcoming Prospex Conference as organised by the PESGB, to be held at the Design Centre Islington from December 13th to 14th 2017.

Located at Booth Number 6, representatives of the UKOGL Trustees along with the Lynx Administration Team would very much welcome the opportunity to meet you to answer any enquiries and to provide an overview of the wide range of activites and resources that the Library has to offer in support of Industry Activity and Academia.

Schools Project – New Resource

We are pleased to announce that a new academic resource, as developed by the University of Derby and funded by UKOGL, is now available through the UKOGL website.

Compiled by Jack Higginson and Martin Whiteley, ‘Maps & Map Interpretation – An Introduction For Geoscientists’ provides a wide range of walk through exercises designed as both an educational tool and a teaching resource.

This can be accessed and downloaded via the Academic Support or Guides links on the UKOGL home page.

Alternatively a PowerPoint presentation or PDF document with embedded Presenter Comments can be accessed here.

Guides Resource

A new ‘Guides’ section has been added to the Main Menu on the UKOGL Home Page, where  additional general support material will be uploaded as it becomes available.

UKOGL Archive – New Lines – September 2017

Over 70 new seismic lines have been added to the UKOGL archive this month. Ranging from offshore Country Durham, the Midlands to South Wales this brings the total Coal Authority post stack line coverage now available through UKOGL to over 3000 lines in both SEG-Y and scanned hard copy section images.

The digital data was not available for these lines and was created by scanning, and vectorizing the hard copy sections to SEG-Y by Lynx Information Systems. UK British National Grid co-ordinates have been inserted in to the trace headers to ensure that the lines are ready for workstation loading and interpretation.

 

Additional Borehole Coverage

As a supplement to our primary Exploration wells coverage we now serve an additional wells layer of selected additional deep boreholes compiled over areas of limited exisiting coverage and control.

Providing access to an expanded Formation Tops database this resource has been compiled from a number of open access sources and sub surface memoirs, primarily derived from information held within the British Geological Survey’s Borehole Scans archive. For further information and access to extensive source records please visit the BGS site.

This compilation is an ongoing project and is still in its early stages, with the initial focus being across the south of England. New data will be added on a regular basis and this layer, shown as blue ringed well spots,  can be displayed on the map via the Wells Tab in the Table of Contents as below.

Coal Authority – New Post Stack Seismic

A new batch of Coal Authority post stack seismic data has been archived and made available to view and license through the UKOGL website.

This adds 112 new lines to the UKOGL coverage and is comprised of both stack and migrated versions. Many of these lines were previously only available as hardcopy sections as the digital data was not available. The SEGY data has been either loaded from the original files or reconstructed by scanning and vectorizing the sections by Lynx Information Systems to recreate the lines.

The majority of the lines highlighted in maroon in the image above, were recorded in the 1990’s. All lines have British National Grid X-Y co-ordinates inserted in to the trace headers and are available to be licensed immediately. Please contact UKOGL for more information regarding these lines or for any of the other data  sets available from UKOGL.

Oldham Associates Regional Report On-Line

We are pleased to announce the addition to our Regional Reports archive of a key legacy study as undertaken by Oldham Associates in 1984 over landward areas of Northern England.

The report, entitled ‘Prospects and Plays in the East Irish Sea and Solway Basins’, provides a geological framework along with a detailed assessment of 13 identified prospects throughout the region.

The report can be accessed via the Regional and Government Studies link (Northern England) on the UKOGL front page or through the ‘catch all’ search function on the on-line map.

We wish to extend our gratitude to both Les Oldham and Robin Grayson, co-authors of the report, for their kind permission to allow this resource to be made freely available through the UKOGL webite.

Both Les and Robin can be contacted directly with regards to this report and also for any prospective studies for which their expertise may be of support.

 

Regional & Government Studies

We are pleased to announce a new resource that provides access to our archive of regional studies as carried out across the UK Onshore. This compliation pulls together a series of key reports as undertaken by UK government departments, the British Geological Survey and other partner organisations, covering such topics as Prospectivity Assessments, Shale Studies and Unconventional Resources.

Furthermore UKOGL will make available additional regional reports as compiled by Operators and Consultants where permissions to release are granted.

This resource can be accessed via the link on the Home page…
