SUPERGRID, our workstation-ready projects for efficient exploration on the Norwegian Continental Shelf.

Across Norway, companies are continuously reviewing, assessing and selecting their favoured exploration options. Matched and merged regional datasets are essential tools for refining geological knowledge about exploration prospects. KADME, CAMA GeoScience and SXICOM are working together to support this exploration activity with fine-tuned data sets and regional interpretations.

The SUPERGRID projects will enhance your exploration activities with smooth and rapid access to integrated 2D/3D seismic and well datasets and high-quality interpretation.

The datasets are delivered in Petrel and DUG for seismic, well data and velocity models. We can also provide support to ensure rapid loading of your own seismic data. Our aim is to deliver what you need for a ready-to-go project for basin modelling and detailed prospect interpretation and evaluation.

High quality seismic with maximum coverage

  • New homogeneous seismic dataset from different public vintages

  • Released 2D and 3D seismic datasets matched for maximum coverage and quality

  • Overlapping 3D surveys merged into a 25m x 25m grid

  • Original geometry used on 2D lines

  • Stranded 3Ds re-gridded and original grid

  • 2D lines used to tie the stranded 3Ds

  • 2D lines spliced where applicable

  • Velocity data provided as a 1000m x 1000m grid, every 100ms

  • New velocity model combined with check shots

Additional services include merging and matching with proprietary seismic datasets and project setup.

Interpreted well data

 

  • Petrophysical (CPl) interpretation of all exploration wells

  • Mud logs and mud gas data

  • Logs, Vcl, ø, Sw, check shot and deviation

  • Detailed salinity (Rw) maps

  • Detailed QEMSCAN® mineralogical analysis of 1050 core samples from selected wells in the Barents Sea to calibrate petrophysical analysis and as input for interpretation

  • The mineralogy distribution and porosity information are provided per sample in an Excel tabular format.  The images of mineral maps come in PNG format and will be organized in directories by well.

The delivery will include:

  • Public datasets for the Barents Sea, Norwegian Sea and North Sea

  • Interpreted datasets in Petrel and DUG format; seismic, well data and velocity models

  • Tabular mineralogy data and mineral maps at 50 μm and 4 μm resolution

  • Synchronised ArcGIS project presenting the location of all delivered seismic, wells, cross sections, etc.

  • Optional delivery of data within KADME's Whereoil software, hosted or on premises, and combined with DISKOS and NPD data. 

Additional services include:

  • GIS support

  • Well automatic downloader to keep you up-to-date with all new and released DISKOS well data
