RECONSTRUCTING THE BARENTS SEAWAY IN THE CENOZOIC – THE BRAVO PROJECT.
Vis sammendrag
The Barents Seaway represents an important marine connection between the Atlantic and Arctic oceans. However, how and when precisely the Barents Seaway formed are not very well understood being overshadowed by its neighbor, the Fram Strait Gateway. The Bravo (Barents Sea Evolution) project will address this issue and aims at reconstructing the Barents Seaway paleobathymetry in the Cenozoic. The key challenge is to quantify the spatial distribution and temporal evolution of km-scale vertical movement of Cenozoic uplift and erosion due to glaciations and pre-glacial tectonism. BRAVO approach requires a comprehensive analysis of off-shelf sediment estimation, lithospheric strength, and other mantle-related processes in order to produce a reliable model. BRAVO will use extensive seismic and well data, and utilize numerical modelling technique using pyGPlates software. BRAVO will also test the paleobathymetry reconstructions by simulating the corresponding sediment source-to-sink in the Cenozoic using pyBadlands, an open-source codes for sediment transport, erosion and depositional processes. BRAVO is a Marie Skłodowska-Curie Actions (MSCA) project funded by the European Union’s Horizon Europe and the Research Council of Norway (2023-2026).

Screening traps and seals for CO2 storage expansion in the northern Horda Platform, Norwegian North Sea.
Vis sammendrag
Evaluation and development of new and exciting CO2 storage opportunities on the Norwegian Continental Shelf is on the rise. Of note is the Aurora site located in northern Horda Platform of the Norwegian North Sea, where injection is scheduled to commence in 2024 under project Longship. While the planned injection volumes at Aurora are over 1.5 megatonnes per year, many more storage locations are required in order to meet international climate mitigation targets by 2050. Other parts of the northern Horda Platform show CO2 storage potential, but additional subsurface characterization is required. As a contribution towards this effort, I present two possible Jurassic storage complexes (Lower and Upper), where I discuss the presence of available storage aquifers, structural traps, as well as top and fault seals. Overall, our work supports the notion that the northern Horda Platform may be capable of hosting a future CO2 storage hub for northern Europe.

Distribution of faulted Mesozoic and Tertiary seals for CO2 storage in the northern Horda Platform, Norwegian North Sea.
Vis sammendrag
This lecture summarizes a recent case study involving the derisking of geological seals for a potential offshore CO2 storage site. In the northern Horda Platform of the northern North Sea, the structural and stratigraphic architecture of the producing Troll East hydrocarbon field is directly analogous to the Alpha CO2 storage prospect in the Smeaheia fault block just to the east of the field. Building on this observation, we have mapped the proven regional seal units of Troll East in order to extrapolate and understand their distribution throughout the northern Horda Platform. Here, we utilize our results to compare Alpha with Troll East, and discuss top and fault seal presence in the context of derisking Alpha’s CO2 storage prospectivity.

Structural traps and seals for expanding CO2 storage in the northern Horda Platform, North Sea.
Vis sammendrag
Full-scale CO2 storage within the Norwegian Continental Shelf is scheduled to commence in 2024 at the Aurora site under project Longship and the Northern Lights JV. While tens of megatons of injected CO2 are anticipated over the coming years, many more storage locations are required in order to meet international climate mitigation targets by 2050. In the event of success at Aurora, the northern Horda Platform region could be further developed into a North Sea CO2 storage hub, but more subsurface evaluation is needed to identify prospective sites. Here, I present two possible Jurassic storage complexes (Lower and Upper), and discuss the presence of available storage aquifers, structural traps, as well as top and fault seals based on the latest 3D seismic and wellbore data. Our results indicate that both storage complex aquifers are preserved throughout the study area, and we have identified a total of 95 Lower and 64 Upper Jurassic fault-bound traps. Mapping, modeling, and formation pressure analyses suggest that top seals are sufficiently thick over the majority of identified traps, and provide vertical pressure barriers between storage aquifers. While across-fault juxtaposition seals appear to dominate the Upper Jurassic storage complexes, Lower Jurassic aquifers are often up-thrown against Middle and Upper Jurassic aquifers, posing a potential risk to CO2 containment for many Lower Jurassic footwall traps. However, I go on to show that apparent across fault pressure differentials and shale gouge ratio values >0.15 correlate at such juxtapositions, suggesting fault rock membrane seal presence. Moreover, I illustrate that aquifer self-juxtapositions are likely zones of poor fault seal within the study area. Overall, our work provides added support that the northern Horda Platform represents a promising location for CO2 storage expansion, carrying the potential to become a future storage hub for northern Europe.

Pre-Salt Carboniferous Basin Configuration and Supra-Salt Evolution of the Nordkapp Basin, Barents Sea: Interplay between Pre-Salt Rift Architecture and Syn-Rift Layered Evaporitic Sequences, Sediment Progradation and Differential
Loading.
Vis sammendrag
Reprocessed regional 2D seismic reflection profiles, 3D seismic data, available wells, and gravity and
magnetic data, together with basin modelling are utilised to comprehend the pre-salt Carboniferous rift
architecture and supra-salt evolution of the Nordkapp Basin (study area: ~150000 sqkm). The Nordkapp
Basin evolved over a basement that had been affected by complex interaction between the Timanian and
Caledonian structural elements. During the late Devonian-early Carboniferous NE-SW-oriented extension,
the Nordkapp Basin consisted of a northern and a southern regional half-graben separated by an
elevated interbasin ridge. During the late Carboniferous-early Permian, a second extension phase took
place with a shift in stress orientation to NW-SE that influenced the two regional half-grabens and caused
the development of seven sub-basins separated by interbasin transfer zones in the Nordkapp Basin. The
relative depth of each sub-basin, the arrangement of structural highs along with evolving master faults
and depositional paleo-environment all controlled the thickness and facies of syn-rift layered evaporitic
sequences (LES).
Some remnant topography existed in the Nordkapp Basin in the earliest Triassic, when a regional
prograding system arrived from the east causing differential loading and triggering the salt movements,
which in turn created significant local topography with mini-basins surrounding the growing salt structures.
The resulting composite basin topography strongly influenced the Triassic progradational sediment
routings and dictated both where the initial deposition could take place and the formation of distinct
depositional fairways. Basin modelling and structural restoration have revealed that once the mobile salt
depleted from the syn-rift LES beneath the axial zone then the salt structure was sourced from
depocenter opposite to it. The salt structures were slightly rejuvenated due to the reactivation of the
Carboniferous structures caused by the far-field stresses propagating during late Triassic in response to
the evolving Novaya Zemlya fold-and-thrust belt farther to the east. The salt was depleted from the synrift
LES by the early Cretaceous as the prograding shelf platform complex buried the salt structures. The
main phase of rejuvenation of the salt structures took place during the early-middle Eocene as a result of
the transpressional Eurekan/Spitsbergen orogeny farther to the northwest until the Cenozoic uplift eroded
most of the post-middle Cretaceous sediments. The spatially diverse salt structures affected the late
Permian to Cenozoic supra-salt sedimentary strata in the Nordkapp Basin which offers an excellent
environment to study the distinct supra-salt structural styles, including turtle structures, secondary and
thrusted welds, bowl vs wedge geometries, collided and secondary mini-basins, salt wings and megaflaps.

Salt tectonics in
the Nordkapp Basin, Barents Sea – Interplay between sediment progradation and differential loading,
syn-rift layered evaporitic sequences and pre-salt rift architecture.
Vis sammendrag
The study utilised reprocessed regional 2D seismic
reflection profiles, 3D seismic data, available wells and
basin modelling to reveal the controlling factors for the
supra-salt sedimentary evolution of the northeastern,
central and southwestern segments of the Nordkapp
Basin. The basin offers an excellent environment for the
study of diverse supra-salt structural styles, including
turtle structures, secondary squeezed and thrusted
welds, collided mini-basins, bowl vs wedge geometries,
salt wing and megaflap. The observed salt structures
show different sizes, shapes, orientations and lateral
extent that affect the late Permian to Cenozoic supra-salt
sedimentation in the Nordkapp Basin.
Some remnant topography existed in the Nordkapp
Basin in the earliest Triassic related to the underlying
late Devonian to early Carboniferous (NE-SW) and late
Carboniferous to early Permian (NW-SE) extension
structures that overprinted on the contrasting Timanian
and Caledonian basement structural grains. A regional
prograding system arrived from the east causing
differential loading and triggering of salt movements,
which in turn created significant local topography with
mini-basins surrounding the growing salt structures. The
resulting basin topography strongly influenced the
Triassic progradational sediment routings and dictated
both where the initial deposition could take place and
the formation of distinct depositional fairways. The
depositional fairways primarily formed by differential
loading and density-driven subsidence caused by the
progradational sedimentation, and have restricted the
subsidence in the mini-basins outside the fairways.
Once the mobile salt was depleted from the layered
evaporitic sequences (LES) beneath the axial zone then
the salt structure was sourced from the depocenter
opposite to it. The salt was evacuated from the LES
diachronically along the strike of the basin as the
earliest passive diapirism occurred in the northeastern
segment and then progressed to the central segment due
to the direction of progradation of the approaching
deltaic system. We suggest that the direction and the
velocity of the prograding system arriving from the east
filled the initial depositional fairways over the syn-rift
LES and the pre-salt rift architecture thus defined the
sedimentary depositional architecture within the
Nordkapp Basin.
The salt structures were slightly rejuvenated due to the
reactivation of the Carboniferous structures caused by
the far-field stresses propagating during late Triassic in
response to the evolving Novaya Zemlya fold-and-thrust
belt farther to the east. The salt was depleted from the
LES by the early Cretaceous as the prograding shelf
platform complex buried the salt structures. The main
phase of rejuvenation of the salt structures took place
during the early-middle Eocene as a result of the
transpressional Eurekan/Spitsbergen orogeny farther to
the northwest until the Cenozoic uplift eroded most of
the post-middle Cretaceous sediments.

Pre-salt Carboniferous basin architecture, structural inheritance and segmentation in the Nordkapp Basin, Barents Sea.
Vis sammendrag
Reprocessed regional 2D seismic reflection profiles, 3D
seismic data, available wells, and gravity and magnetic
data were used to study the pre-salt rift architecture in
the Nordkapp Basin, Barents Sea, and its impact on the
evaporite accumulations and distribution of salt
structures. The basin is subdivided into three main
segments (the northeastern, central, and southwestern
sub-basins) and has evolved over the complex
interaction between the Timanian and Caledonian
structural basement grains. Each segment is
characterized by prominent magnetic anomalies related
to the Timanian and Caledonian structural inheritance.
The rotated magnetic lineations associated with the
Caledonian structures beneath the Finnmark Platform
pass through the central segment, where the Middle
Allochthonous Front creates the major sub-division
between the two structural grains. We suggest that the
rheological properties, locations, orientations and
interaction of the parts of the basement influenced by
Timanian and Caledonian structural grains together with
two subsequent extensional phases, have strongly
influenced the shallower pre-salt rift architecture.
During the late Devonian – early Carboniferous NE-SW
-oriented extensional phase, the Nordkapp Basin
consisted of a northern and a southern regional halfgraben
separated by an elevated interbasin ridge. The
hinged margins of the northern and southern regional
half-grabens were restricted against the NW-SE-striking
graben beneath the Veslekari Dome and Troms-
Finnmark Fault Complex, respectively. The internal
configuration of the regional half-grabens was affected
by the NW-SE-striking master faults. During the late
Carboniferous to early Permian, a second extension
phase took place with a shift in stress orientation to NW
-SE and influenced the two regional half-grabens. In
particular, a transfer fault with the character of an interbasin
transfer zone (the northern transfer zone) divided
the northern regional half-graben by separating its
hinged margin (incipient northeastern segment) from the
deeper part (incipient central segment). At the same
time, the elevated interbasin ridge acted as a southern
transfer zone, separating the incipient central and
southwestern segments of the Nordkapp Basin. The
Thor Iversen, Polstjerna, Måsøy and Nysleppen basin
border fault systems were formed during the second extensional
phase and reshaped the internal configuration
of the two regional half-grabens.
The structural interaction between the spatially variable
Timanian and Caledonian structural grains overprinted
by two subsequent phases of NE-SW and NW-SE
extension caused the development of seven sub-basins
in the Nordkapp Basin. Internally within the sub-basins,
the evolving structural elements including cross-cutting
master faults and structural highs have influenced the
deposition and facies of the layered evaporitic sequences
and defined the location of subsequent salt
structures. We suggest that the relative depth of each
sub-basin, the arrangement of structural highs along
with the evolving master faults and the depositional
paleo-environment all controlled the thickness and
facies of the syn-rift layered evaporitic sequences.

Regional containment derisking for future CO2 storage in the Horda Platform, Norwegian North Sea.
Vis sammendrag
Full-scale CO2 storage within the Norwegian Continental Shelf is scheduled to commence in 2024 at the Aurora site under project Longship and the Northern Lights JV. While tens of megatons of injected CO2 are anticipated over the coming years, many more storage locations are required in order to meet international climate mitigation targets. In the event of success at Aurora, the remaining Horda Platform region could be further developed into a larger North Sea CO2 storage hub, but more subsurface evaluation is needed to identify prospective sites. Here, I present two possible Jurassic storage complexes (reservoirs and seals) and discuss some of my ongoing PhD work related to derisking traps, seals, and overburden geology in the region. It is hoped that these results can later be leveraged for more site-specific analyses so that new prospects can be matured to help supplement the storage volumes at Aurora site and to further develop CCS operations in the North Sea.

Geological derisking of a potential CO2 storage hub for Europe in offshore Norway
.
Vis sammendrag
A Norwegian demonstration of the full-scale CCS value-chain is scheduled to commence in 2024. Carbon-dioxide captured from industrial sites in eastern Norway will be transported west, processed, and injected into the subsurface at the Aurora site in the northern North Sea. While Aurora represents a sizeable CO2 storage location, many more are needed in order to significantly reduce global emissions and meet climate mitigation goals. Ideally, developing additional storage sites within the vicinity of Aurora would expand on its soon-existing infrastructure, and create a potential CO2 storage hub for Norway and northern Europe. However, geological risks to CO2 containment must be identified and assessed before such a development could take place. Here, a summary of ongoing subsurface characterization work is presented in support of the storage hub concept in this region.

Top and lateral seal characterizations for CCS in Jurassic saline aquifers, Horda Platform, Northern North Sea.
Vis sammendrag
Capture of industrially sourced CO₂ and transport to the Aurora subsurface storage site in the northern North Sea are approved to commence in 2024 under the direction of the Longship and Northern Lights projects. Results from well 31/5-7 drilled in early 2020 within exploitation license EL001 confirmed suitable parameters at Aurora (e.g., porosity, injectivity, etc.). While the geology of the site proves promising for CCS, it remains imperative to mature additional locations in order to meet current climate mitigation targets and establish the Horda Platform as a European storage hub.
Planned injection and containment at Aurora will be hosted by the Lower Jurassic Dunlin Gp stratigraphic storage complex (storage aquifer and seals), however, the Upper Jurassic Viking Gp represents an additional storage complex. Moreover, Aurora is located in the western-most of three large, basement-rooted fault blocks, each showing storage potential. Hundreds of thick- and thin-skinned faults create two- and three-way structural traps for both storage complexes in all three fault blocks. Some Viking Gp traps contain hydrocarbons (e.g., Troll field), providing direct analogs, but should be avoided for CO₂ storage until the end of their production life around 2050. Nevertheless, the remaining structural traps currently make the most attractive storage prospects, as they can focus injected CO₂ in a predicable fashion, particularly during the early stages of the sequestration process before other trapping mechanisms take over (e.g., residual trapping).
As both top and lateral seals must completely envelop the storage aquifer, understanding the distribution and nature of the seals is critical for predicting subsurface CO₂ containment. In order to provide insight towards additional CCS potential in the Horda Platform, we present a summation of top and lateral seal mapping, modeling, and observations for the Dunlin and Viking Gp storage complexes in the three major fault blocks.
For the Dunlin Gp storage complex, interpretation of its top seal distribution from 3D seismic and wellbore data confirm seal presence in all three fault blocks, including that of the Aurora site. The majority of small thin-skinned faults at the Jurassic stratigraphic level and create aquifer juxtapositions against the top seal, while larger thick-skinned faults must provide membrane seals along the largest closures. In these latter cases, the Dunlin Gp sandstone aquifer is up-thrown and juxtaposed against the overlying Viking Gp sandstone aquifer, but shale gouge ratio analysis and regional aquifer pressures suggest favorable membrane fault seal potential. Top seal formations above the Viking Gp aquifer are determined to be present throughout the Horda Platform, but only the eastern-most fault block is currently prospective for CO₂ storage, given the high risk of contaminating producing fields in adjacent fault blocks. Fault seals in this case appear to be juxtaposition-controlled, even for thick-skinned faults, which are analogous to Troll East. Considering the availability of structural traps for expanding storage activities in the Horda Platform, our work infers that the presence top and lateral seals is probable for both the Dunlin and Viking Gp storage complexes.

Structural analysis of the Smeaheia fault block, a potential CO2 storage site, northern Horda Platform.
Vis sammendrag
Smeaheia, a prominent fault block located on the Horda Platform, northern North Sea is identified as a potential subsurface CO2 storage site. We utilise the GN1101 3D and regional 2D seismic surveys to generate a high-resolution subsurface geomodel to inform the structural style and evolution of the fault block, to investigate geological controls on proposed CO2 storage and provide a geometric framework as a basis for future analyses. Two basement-involved (first-order) north-south trending fault systems, the Vette Fault Zone (VFZ) and the Øygarden Fault Complex (ØFC), bound the 15 km-wide fault block. Apart from activity during the Permo-Triassic (Rift Phase 1) and the Late Jurassic–Early Cretaceous (Rift Phase 2), we present evidence that rifting in this part of the North Sea continued into the Late Cretaceous with minor reactivation in the Palaeocene–Eocene. Two segments of the VFZ interacted and linked at a relay ramp during Rift Phase 2. Second-order (thin-skinned) faults show basement affinity and developed during Rift Phase 2 in two distinct pulses. A population of polygonal faults intersects the overburden and developed during the Eocene to middle Miocene. We have revised the areal extent of two structural closures that define the Smeaheia fault block, Alpha (VFZ footwall) and Beta (ØFC hanging wall) which consist of Upper Jurassic Viking Group target formations. Cross-fault juxtaposition analysis of the VFZ and second-order intra-block faults are presented and inform pressure communication pathways between the Smeaheia and Tusse fault block, as well as reservoir integrity and compartmentalisation. The geomodel further identifies important geological controls on CO2 storage in the fault block including a thinning caprock above the Alpha structure, and identification of hard-linkage between deep tectonic faults and shallow polygonal faults. Fault reactivation analysis was conducted on depth-converted faults to determine the risk of up-fault CO2 migration. Hydrostatic and depleted scenarios were modelled. Faults are modelled as classic cohesionless structures but also utilising parameters (cohesion and friction angle) derived from host rock mechanical analysis.

The doctoral thesis is a collection of four published journal papers, which investigate the influence of the basement inheritance on the pre-salt basin configuration and its effects on the accumulation of the layered evaporite sequence, salt tectonics and post-salt sedimentation in evaporite-influenced rift basins. The thesis has shown that rheological properties, locations, orientation and interaction of inherited structures created zones of weakness that influenced the development of complex pre-salt basin architecture along with subsequent regional extensional phases. Consequently, the syn-rift to post-rift processes within discrete accommodation space of varying depth and depositional paleo-environment, have influenced the thickness and facies (mobile to non-mobile) of the layered evaporite sequence. The study highlights that the regional extension and prograding sediment influx direction, the sediment transport velocity and the sediment thickness influenced the dynamics of the early to late passive diapirism, the salt expulsion and the depletion, together with the layered evaporite thickness and facies that were affected by the pre-salt rift architecture. The salt structures and evaporite-cored domes were rejuvenated due to far-field contractional stresses and eventually uplift eroded the successions over their crests.
