APA 2017 data pack
Kadme, Cama GeoScience, Sxicom and Rocktype present an extensive data package for the 2017 Awards in Predefined Areas (APA) of the Norwegian continental shelf. The pack, designed to guide licensing decisions for the 2017 APA round and beyond, has a particular focus on the the Barents Sea. It includes:
- Merged and matched 2D and 3D seismic data from all 3 APA areas
- Petrophysical well interpretation of 100 Barents Sea wells
- QEMSCAN analysis of 1000 Barents Sea core samples
QEMSCAN of 1000 Barents Sea samples
Rocktype is performing the largest ever QEMSCAN survey by scanning 1000 samples from 11 Barents Sea wells. This survey showcases the new high-volume QEMSCAN 50 service from Rocktype. This fast, low-cost service enables clients to get precise mineralogy and porosity throughout all cored intervals in these wells.
We have sampled at 0.5m or 1m spacing from all available core. This provides a continuous mineralogy record to match directly to the well log.

High resolution QEMSCAN petrography
From the samples scanned at 50 μm, we will select 50 representative samples to be scanned in high resolution as QEMSCAN 4. These high resolution scans enable detailed study to texture, pore lining phases and mineral association.
High quality seismic data 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
Seismic clean-up and quality control
- Scan 3D data trace headers for consistency
- Compare navigation in trace headers with navigation file
- Check for data spikes
- Check for seismic anomalies
Petrophysical interpretation of 100 Barents Sea wells
The experts at Cama Geoscience will interpret well data from 100 Barents Sea exploration wells.
- Petrophysical (CPl) interpretation of 100 exploration wells
- Mud log 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
- Well data will be matches to corresponding QEMSCAN analysis data
Data delivery – speedy online access
The initial data set will be provided on disk, with updates provided online through the Kadme Whereoil platform. The delivery includes:
- Public APA 2017 datasets for the Barents Sea, followed by updates with the Norwegian Sea and North Sea
- Interpreted petrophysical datasets in Petrel and DUG format; seismic, well data and velocity models
- QEMSCAN 50 mineral map images and tabular mineralogy from 1000 samples
- High resolution QEMSCAN 4 mineral map images from 50 samples
We are grateful to Statoil for advice with devising a sampling programme from five key Barents Sea wells and their permission to make the resultant QEMSCAN data available through our APA 2017 multiclient study. We hope this 800 sample dataset will provide great insights to Barents Shelf explorers as they enter the APA 2017 round and beyond.
