Reduce the risk in picking prospects with the only unified regional datasets 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 as well as high-quality interpretation.

High quality data is a vital resource for the oil and gas industry, particularly when making major licensing decisions. The challenges lie not only in sorting through the huge mass of available data, but also in making it easier to access the right data so that teams can start making important decisions sooner.

Our industry-leading experts have extensive experience of the Norwegian Continental Shelf, enabling them to ensure effective data synchronization and high-quality interpretation.

SUPERGRID includes velocity models, core sample analysis and special geological/seismic studies to support exploration teams over APA/BR activities. The value of this product is guaranteed by extensive 2D/3D seismic data merges and well data setting on the main exploration areas (Barents Sea, Norwegian Sea and North Sea).

All of our work is subject to regular and rigorous quality control during the interpretation phase.

The datasets are delivered in Petrel and DUG for seismic, well data and velocity models. We can also provide support to ensure rapid seismic data loading. 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 1,050 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.

Project data delivery – speeding up data access and prospect picking

Kadme’s data management experts will provide datasets on disk. Updates will be made available online.

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 premise, combined with DISKOS and NPD data.

Additional services include:

  • GIS support

  • Well automatic downloader provides a synchronised, local repository of entitled, new and released DISKOS well data.

Customer references

“The comprehensive SUPERGRID data package has been of great value for us as a startup oil company in Norway. A seamless seismic merge of mutual consistent surveys backed up by a checkshot corrected velocity cube make interpretation, seismic attribute generation and depth conversion easy. All this, together with a consistent well data base with picks and CPI logs, has been crucial for our screening of opportunities and regional understanding of the Norwegian Continental shelf. Everything is nicely organized in Petrel and IP and has saved us for a lot of data management work. KADME and its partners SXICOM and CAMA GeoScience has also been helpful with services and updates during the implementation.”

“Kadme, SXICOM and CAMA GeoScience delivered Supergrid project comprising all the public Norwegian Sea well data with conditioned and QC’d logs, all the public 2D and 3D seismic surveys and a comprehensive regional geological interpretation. 2D and 3D surveys were QC’ed and conditioned and merged into one regional dataset. They have done detailed petrophysical interpretation for more than 200 wells with a very elaborated description of their workflow. We are happy with the delivered database and with their high quality petrophysical interpretation work”
