April 2020 | Hearing blocks for APA 2020 in VBPR core area

APA 2020 opens for sub-basalt exploration

Fenris Graben, Skoll High, Gjallar Ridge and Rån Basin soon open for exploration. Over the last 20 years, VBPR and TGS have invested in geological, geochemical and geophysical data in the outer Vøring basin and escarpment; initially with the Geophysical Atlas of the Møre and Vøring Basins (1999-2012), the North Atlantic Seafloor Sampling (2000-2016), and the Petroleum Implications of Sill Intrusions (2000-2003).

In 2013 a major effort was started, in collaboration with supporting oil companies, to unravel the Volcanic Margin Petroleum Prospectivity (VMAPP) of the outer continental margins around the North Atlantic. A breakthrough in petroleum system understanding was made with the outstanding seismic resolution of the P-Cable well tie line (2015), and with the access to the high-quality 3D cube CVX1101 (released 2015, currently being reprocessed with support from VBPR). Huge investments by TGS in new high-quality 3D coverage (AM17-18-19), and advanced reprocessing with high precision velocity models, has recently resulted in stunning  imaging improvements of the sub-basalt stratigraphy.

In addition to the new and reprocessed seismic data, applicants in APA2020 will need access to the Vøring Transform Margin Sampling (2000), Vøring Sampling (2016), the P-Cable 2D well-tie line (2015) and the deliverables from the VMAPP 1 and 2 project (2013-2021). Please contact VBPR or TGS sales representatives for quotations.

February 2020 | Milestone Paper on mid-Norwegian geology

Regional work on mid-Norwegian continental shelf published (Dmitry Zastrozhnov et al)

Over the last 15 years, a significant data accumulation including new and reprocessed 2D seismic reflection lines, large 3D seismic surveys, regional interpolated 3D volume (J-Cube MN), potential field data, new exploration wells, seabed sampling and revised bio-lithostratigraphic schemes enabled an improved understanding of the mid-Norwegian margin. New and reprocessed seismic data achieved a better imaging of intra-volcanic sequences and sub-basalt basin geometries in the outer domain of the mid-Norwegian margin and deep basin structures in the central parts of the Møre and Vøring basins.

The main goal of this paper was to compile, integrate and jointly interpret this comprehensive geological and geophysical dataset to improve the understanding of processes controlling the formation and development of the deep Cretaceous-Paleocene basins of the mid-Norwegian margin. Another important task was to update tectonostratigraphic framework for the Møre and Vøring basins. Several new structural elements have been identified and described in the central and outer Møre and Vøring basins including the Ervik Ridge, Bylgja Ridge, Kolga High, Hevring High and Dufa High. Previously defined structural elements in the outer Vøring Basin (e.g. Rån Ridge, Vigrid Syncline and Gjallar Ridge) have been revised. Distal elevated crustal marginal plateaus were suggested to present in the outer Møre and Vøring basins.

The paper shows that the Early Cretaceous to Paleocene evolution of Møre and Vøring basins is associated with episodic phases of extensional events separated by intermediate cooling phases. This study also shows that the Vøring and Møre basins have different structural and sedimentary evolution. The pre-breakup evolution and configuration of the outer mid-Norwegian margin significantly differ from the previously proposed Iberian-type model and this may provide additional industrial interest in this yet underexplored region.

February 2020 | VBPR contribution to higher drilling efficiency

Application of Resonance Enhanced Drilling (RED) technology to coring

In a comparison between the efficiency and quality of cores obtained using RED technology against conventional coring, improvements in penetration rates of up to 180% compared to conventional coring for the same drilling conditions were achieved. The project was performed i cooperation between the University of Aberdeen, Northeast Petroleum University in China and VBPR (J. Millett).

January 2020 | Join inspiring discussions on Energy Transitions

Ms Ingrid Paola Tello Guerrero (ALS) and Mr Benjamin Bellwald (VBPR), conveners at EAGE 2020, invite you join inspiring discussions.

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.

December 2019 | Explanation for the structural rise of Mjølnir’s central peak

Romain Corseri, VBPR with paper on Mjølnir Impact Crater

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.

September 2019 | VBPR represented in EAGE Special Interest Community

Benjamin Bellwald represent VBPR in EAGE Special Interest Community on Decarbonization and Energy Transition

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

August 2019 | OGIC Project Case Study: VBPR UK with Univ. of Aberdeen

Applying Resonance Enhanced Drilling to coring

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.

July 2019 | Atlantic Margin Revival

Atlantic Margin Initiative (TGS) - the key to new gas reserves for Europe

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.

June 2019 | Understanding volcanic facies in the subsurface

A combined core, wireline logging and image log data set from the PTA2 and KMA1 boreholes, Big Island, Hawai‘i

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.
