Our dedicated session focuses on real actions contributing to a carbon
footprint reduction throughout different geoscientific activities, including
CCUS, geothermal and new technologies. The session brings together
key speakers from universities, service companies, governments and
authorities, sharing knowledge of the strategies used and lessons learned.
The effect of far-field tectonic stresses on the central peak uplift was investigated using new high-resolution P-Cable and conventional seismic reflection data. Impact-induced faults were activated by uplifted segments of the central peak up to 500 m above the platform level during one or several contractional episodes. Differential compaction, previously seen as the main deformation process, may have increased the original central peak height by only ~10 m. The mobilization of impact-shattered rocks by tectonic compression provides a new and robust explanation for the structural rise of Mjølnir’s central peak.
Senior geologist John Millett of VBPR believes the time has come to drill through magmatic rocks on the Norwegian continental shelf. This can lead to new oil discoveries.

The overall objective of the group is to promote knowledge and develop skills among geoscientists and engineers working with Decarbonization & Energy Transition technologies.
The kickoff call was hold September 6th 2019, and Karin de Borst from Shell was elected president with the commitments to:
- Attract new members, publish relevant news, exchange information in the LinkedIn group
- Support focused events by providing advice on topics, speakers, reviewing papers, etc
- Collaborations with other EAGE communities
VBPR approached OGIC to support a proof of concept project to identify if Resonance Enhanced Drilling (RED) could be used for coring. OGIC supported VBPR’s project with the RED team from the University of Aberdeen.
The project had three principle goals:
1. Test RED technology efficiency with a coring bit.
2. Attain equal or improved core quality for the homogeneous test rocks.
3. Improve ROP of core cutting without sacrificing quality.
The research demonstrated no negative effects, no fracturing and that the cores were of good quality. Importantly, the pilot project demonstrated that ROP (rate of penetration) could be substantially improved for coring applications by as much as 50%. This increase could be extremely important for longer coring runs and could have important applications beyond industry such as IODP scientific drilling where coring for up to and over 1 km is relatively common. The next stage for this project will be to initiate a development project to bring the coring technology to market.
After 20 years of SeismicGravityMagnetic Integration (SGM) and Seafloor Sampling in the Arctic region, VBPR provide TGS with unique regional competence in chasing reservoirs for new gas resources in under-explored Møre-Vøring Basins and marginal highs. With the proximity of the East-Greenland continental margin, huge traps disguised by basalts can have excellent reservoirs.
To help understand volcanic facies in the subsurface, data sets that enable detailed comparisons between down-hole geophysical data and cored volcanic intervals are critical. The data set and results of this study include findings which should enable improved borehole facies analysis through volcanic sequences in the future, especially where down-borehole data and images but no core are available.
The field course was run by VBPR, DougalEarth and Breno Waichal from Florianopolis University as part of the VMAPP project. Geoscientists from Petrobras and CNPC participated to study the interactions between volcanism and prospective sedimentary basins. Fieldwork remains a vital aspect of exploration and production within complex volcanic basins such as the pre-salt offshore Brazil. Thanks to all participants for making it a special week.
High-resolution 3D site characterization can deliver reliable quantitative property volumes of the subsurface when based on seismic data able to image meter-sized objects. Following the theoretical analysis of seismic wave propagation in the shallow sub-surface (Lebedeva-Ivanova et al., 2018), Nina will present two case studies based on re-processing of 3D P-Cable seismic data.
