Seafloor Sampling Cruises
- Recover in situ sediments for seismic tie in areas with no well
- Sample seep localities for identification and characterization of active petroleum systems
- Improve geological understanding of frontier basins
Our work areas are in the NE and NW Atlantic conjugate margins with focus on licensing blocks and important areas for future development. Seabed sampling results are important to improve licensing applications, constrain basin models, and increase success rates in exploration for oil and gas in frontier basins.
The seabed above potential hydrocarbon traps is tested for seepage using samples collected with a gravity corer and analyzed with two geochemical (APT and AGI) and one microbial (MPOG) methods. Stratigraphic samples collected across exposed fault escarpments are age dated and tested for source and reservoir rock properties, and results presented as a pseudo well.
New seabed samples reveal active Jurassic oil seeps and Mesozoic sedimentary sequences on the Jan Mayen Ridge.
Seismic tie to pseudo-well. Relevant for sub-basalt exploration on the Norwegian margin.
The ABS12 (Ammassalik Basin Sampling 2012) survey is located in a frontier area for oil and gas exploration offshore SE Greenland. A total of 21.75 m of sediments were recovered from nine coring sites, showing evidence of seepage of hydrocarbons.
