New Data Available From UKOGL in Warwickshire: Daw Mill 3D Seismic & Borehole LAS Data

UKOGL are pleased to announce that post stack seismic data and digital LAS data located over the Daw Mill 3D survey in Warwickshire have been added to the UKOGL archive. The data is available to download via the UKOGL interactive map.

The new Coal Authority data over the area displayed in the map below can be accessed for free under the Open Government Licence.

The available post stack data for the Daw Mill survey was originally recorded and processed in 2002, 2004, 2005 and 2011, expanding the coverage to the South West of the original 2002 survey with each subsequent year of recording.

The final 2011 merged and reprocessed post stack 3D data volume provides full seismic data coverage over the Daw Mill survey area.

In support of the available 3D seismic, LAS data is available to download for 32 of the 37 coal boreholes that are currently displayed by UKOGL over the area of the Daw Mill 3D survey, and this includes comprehensive logging suites for the newly added Eaves Green Lane BH and Keatley Pool BH.

These two new data sets add to the coverage that’s already provided by the 2D Coal Authority seismic data over this area of Warwickshire (displayed in the map below). All Coal Authority data is available to download for free from the UKOGL interactive map.

Isle of Wight Offshore 2D Seismic Data now available from UKOGL

In support of the recent release of 2D, 3D seismic and well data located over Poole Bay, UKOGL have made available for download a selected set of data located offshore to the southwest of the Isle of Wight which provides greater coverage to tie this newly designated landward area to eastern onshore data. 11 of the 37 lines in the OX98-90 survey run onshore to enable seamless interpretation from onshore to offshore. The data set includes reprocessed 2D versions not available in the UK National Data Repository (NDR). 

Instructions on how to access this data can be accessed via the Poole Bay Blog post here.

The intention of this exercise is to make it easier for interested parties to study this key area of British Geology. Additional offshore 2D data is available from the NDR but coordinates will need to be transformed to OSGB to match.

Poole Bay 2D, 3D Seismic and Well Data now available from UKOGL

Now that Poole Bay has been designated a “Landward” area, UKOGL has archived and made available for download a selected set of data located in OSGB (National Grid) projection to enable seamless interpretation from onshore to offshore. These data include reprocessed offshore 2D and 3D versions not available in the UK National Data Repository (NDR).  Well data, including LAS files, have been copied from the NDR database and relocated in OSGB.

The intention of this exercise is to make it easier for interested parties to study this key area of British Geology. Additional offshore 2D data is available from the NDR but coordinates will need to be transformed to OSGB to match.

Seismic Data Access:

The seismic data can be accessed by selecting the individual 2D lines and 3D surveys or by using the ‘Area Selection’ tool. The seismic data that is available for each line or survey is listed under the ‘SEGY’ tab of the information box. If interpreted versions are available they will be shown under the “IMAGES” tab of this box.

Well Data Access:

Onshore and ‘Offshore’ wells are presented as separate data layers and can be displayed via the options in the Contents Panel – Wells>Surface Locations>Well class>NSTA (Offshore) Wells.

Individual well layers can be displayed and made available for selection by switching each layer ‘on or off’ to filter the well presentation.

To access the available well data, multiple wells can be selected and highlighted using the ‘Area Selection’ tool or individually by selecting just the well spot location.

Select the ‘Downloads’ tab in the well information panel to access the list of available files.

To access, view and download data click on the ‘ID’ information box and follow the instructions provided.

UKOGL Seismic Data – Interpreted Images – Access, View & Download

UKOGL have implemented a new website feature that provides direct access to over 2400 interpreted onshore seismic images.

The interpreted images have been compiled and collated from reports currently held by UKOGL and can be viewed and downloaded  alongside  the seismic images that are already available for each onshore line on the website.

The interpretations may be based on pre- or post-drill prospect assessments and well results may have indicated that changes are necessary. For additional context please view the associated source reports where available, or the drill dates, finalised tops and times for any wells associated with the prospect

Neither the UK Onshore Geophysical Library nor the original interpreters warrant the integrity of these data and will not be liable in contract or in tort for any loss, damage or expense of any nature suffered by the user as a result of the use of, or reliance on, these data
