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.
EAGE 2019 Workshop 2:
Seismic Inversion for Marine Overburden Characterization
With more than 100 3D surveys acquired in all the oceans of the world, the P-Cable technology has revitalized research on glacial landforms, sedimentary processes and offshore geohazards, and also has great impact on exploration of shallow oil and gas reservoirs (ref. Wisting oil field, Barents Sea).

The EGU General Assembly 2019, taking place in Vienna (Austria) on 7–12 April 2019, will bring together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. B. Bellwald (VBPR), R. Barrett (University of Kiel), B. Manton (VBPR) and S. Planke (VBPR) will present results from ongoing R&D projects.
New paper by B. Bellwald et al, characterizing meter-scale URU landform assemblage of the SW Barents Sea using P-Cable high-resolution seismic data. URU landforms are imaged in a quality comparable to conventional multi-beam echosounders.
The Wisting team has successfully combined data from six exploration and appraisal wells with 3D seismic data (both P-Cable high-res data and conventional broadband) and Controlled Source Electro Magnetic (CSEM) data in the technical studies for subsurface optimization.
P-cable has enabled very detailed interpretation of reservoir heterogeneity and compartmentalization and as a result also more accurate volume prediction (see also "Wisting is Growing" - expronews)
Synthesis report presenting our conjugate margin approach for exploring the outer mid-Norway and SW Barents Sea margins by integrating seafloor sampling results, geology, and plate reconstructions models to understand the hydrocarbon prospectivity of these frontier areas.
Report will be available Q1-2019
Rachel Barrett (Uni Bremen) was invited to work on the Tampen slide in the Norwegian Sea using the AM17 high resolution 3D seismic cube recently collected by TGS. The work is part of the European Training Network SLATE, where VBPR contributes as partner.
The "10th Hydrocarbon Exploration and Development Congress” was organized by the Argentine Oil and Gas Institute (IAPG) at the Intercontinental Hotel, Mendoza. This Congress, more commonly known as “ConExplo”, is the most important technical event of the Oil & Gas industry in Argentina.
