De-risk prospect picking with the only unified regional datasets on the Norwegian Continental Shelf

Across Norway, companies are continuously reviewing, assessing and selecting their favored 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.

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 activity. The high value of the end 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 modeling and detailed prospect interpretation and evaluation.

High quality seismic with maximum coverage

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

  • 3D surveys merged into 25m x 25m grid where applicable

  • Original geometry used on stranded 3Ds and 2D lines

  • 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 using DUG depth conversion to deliver depth-converted seismic data

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

Interpretation of 100 exploration wells in the Barents Sea

 

  • Petrophysical (CPl) interpretation of the 100 exploration wells

  • Mud logs and mud gas data

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

  • Detailed salinity (Rw) maps

  • Calculated porosity is calibrated to measured core porosity

  • Interpreted NPD tops

Detailed core analyses of petrophysical properties, mineralogy and textures  

We will also deliver an extensive petrographic study of Barents Sea exploration wells using QEMSCAN technology, thanks to our collaboration with Rocktype.

  • 1000 core samples analyzed with QEMSCAN at 50 μm for precise mineralogy and porosity values and calibration of log values, including Vcl, gamma, density and ø

  • 50 samples analyzed at 4 μm for detailed textural information enabling study of grain shape, pore size distribution and pore lining phases

The mineralogy distribution and porosity information will be provided per sample in an Excel tabular format.  The images of mineral maps will come in PNG format and will be organized in directories by well. Each image will have sample ID, well, depth and a scale bar printed on it and sample ID, well and depth in the filename.

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 APA 2017 datasets for the Barents Sea, followed by updates with the 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

Additional services include:

  • GIS support

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