Abstract The NE Atlantic volcanic rifted margins include vast underexplored basin areas neighbouring mature petroleum-producing regions. We appraise the cross-border prospectivity of outer and central Faroe–Shetland, Møre southern Vøring basins present insights from extensive new 3D seismic surveys. Regional surfaces are used to compile a profile highlighting key discoveries UK Rosebank field in SW Norwegian Ormen Lange NE. Cretaceous Paleocene reservoirs remain main exploration focus...
Abstract Unravelling past, large-scale ocean circulation patterns is crucial for deciphering the long-term global paleoclimate. Here we apply numerical modelling to reconstruct detailed paleobathymetry-topography of southwestern inlet Barents Seaway that presently connects Atlantic and Arctic oceans. Subaerial topography was likely enough block Water from entering in earliest Eocene (c. 55 Ma). The water may have entered middle 47 Ma) as observed major basin subsidence, but paleotopographic...
K-feldspars form important detrital and authigenic components in sediments but may be difficult to separate by conventional means for isotope analysis, particularly geochronology. UV lasers are being increasing applied situ analysis since they strongly absorbed clear minerals such as K-feldspar, can achieve a spatial resolution of better than 20 μm individual Ar/Ar analyses. Here we demonstrate separation K-feldspar with mean age 423±14 Ma overgrowths 138±5 clastic from the Msolwa Group...
The shallow migrating hydrocarbon fluids in the western Barents Sea are usually found to be associated with high seismic amplitudes. We have attempted characterize such high-amplitude anomalies Hoop Fault Complex area of Sea. workflow is devised for discrimination that presence hydrocarbons from those not, and quantifying them further includes computation a set attributes their analyses. These comprise coherence, spectral decomposition, prestack simultaneous impedance inversion, extended...
Summary The outer Møre and Vøring basins offshore mid-Norway are vast underexplored areas. By integrating interpretation of new seismic 3D data, as well regional 2D, 2Dcubed, potential field we identify targets for future hydrocarbon exploration. Here present an integrated the crustal structure across Basin indicating that Cretaceous infill basin thins towards western margin. thinning upper sequences suggests lower Jurassic plays could be viable in parts basins. Imaging margin is complicated...

Summary Quaternary and Neogene sediments are commonly known for their sealing properties potential drilling hazards. However, examples such as the Peon Aviat discoveries in North Sea show that shallow reservoirs can be prospective. In this study, we use 2D 3D seismic data combined with well information to document new unconventional play models from subsurface of Norwegian Continental Shelf. These plays include (i) glacial sands an ice-marginal outwash fan, sealed by stiff subglacial tills...
Summary A dramatic reduction in global greenhouse gas emissions is necessary to achieve climate change targets. Wide ranging measures are required reduce with carbon capture and storage forming a vital component. Current sequestration occurs volumes of Mt/a into dominantly sedimentary reservoir rocks. Pilot tests have demonstrated that basalt reservoirs provide an alternative permanent scenario (e.g. Carbfix project). Here, we use 2D 3D seismic data combined well identify map potential safe...
Summary Europe need more energy supplies in the current geopolitical situation. Natural gas is a key source and Norway stepping up to meet demand. The Norwegian Sea sit relatively close this market big parts of basin still poorly explored or not at all. Atlantic marginal highs covering 25,000sqkm, about 5 quadrants latitude, have no exploration wells. This despite large structural closures, great two-sided migration catchment areas, Pre-Cretaceous Paleogene age reservoir potential. Latest...
Summary The Gjallar Ridge is a major high along the NW margin of Vøring Basin, offshore Mid-Norway. In this area are voluminous volcanics. While previous wells have targeted crest, or more landward in Vigrid Syncline, we consider flanks to be prospective. By using 3D seismic data and well show that there numerous amplitude anomalies on ridge Paleogene, both north south Ridge. We look detail at Rån Flow, which interpret potentially dacitic flow coming from Transform Margin. Margin would been,...

While carbon capture and storage (CCS) has been recognized as a major enabler to reduce the amount of CO2 released into atmosphere, industry is still in its infancy. Both new technology cost-effective approaches will be necessary if CCS live up potential global warming decades come. Energy data companies such TGS can, with help from partners, work on concepts technologies that key for market, current products made oil gas market can potentially repurposed use CCS. Technologies are also being...

Summary In this paper we present best practices, learnings and benefits of using triple source configurations in connection with large marine exploration campaigns. The utilization more sources behind a streamer vessel will increase efficiency improve sampling between the streamers leading to cost savings improved quality data. addition, setup two sub-arrays instead three sub-arrays, reduce sound pressure level from each source, hence reducing environmental impact shot. However, despite...

Increased resolution and quality in imaging processing of towed marine seismic data can be obtained by acquiring multiple source lines along single sail lines. Doing so, using blended shots typically forces a trade-off between inline sampling length non-interfering time windows against the number crossline sources. Instead, encoding sources means signal apparition, it is possible to acquire set that well sampled on source-side both inline. We present results from recent apparition...
Abstract The Hoop area in the Barents Sea (Norway) is a frontier province with limited well control. It was initially regarded as gas-dominant hydrocarbon province, but explorationists are viewing new interest after successful Wisting oil discovery. Despite this success, considered high-risk due to inefficient sealing, and apparent absence of high-quality reservoir sands. This paper demonstrates how integration 3D seismic controlled source electromagnetic (CSEM) data can help de-risk these...
