Article
Full-text available
The rate of seismicity in the hydrocarbon‐producing Fort Worth Basin of north‐central Texas, which underlies the Dallas–Fort Worth metropolitan area, increased markedly from 2008 through 2015, coinciding spatiotemporally with injection of 2 billion barrels of wastewater into deep aquifers. Although the rate of seismicity has declined with injection...
Article
Full-text available
Faults play an essential role at many potential CO 2 storage sites because they can act as conduits or barriers to fluid flow. To contribute to the evaluation of the Aurora storage site in the northern North Sea, we perform a structural characterization and assessment of across-fault seals that displace the Lower Jurassic storage complex. We find t...
Preprint
The maturation of geological CCS along the Norwegian Continental Shelf is ongoing in the Norwegian North Sea, however, more storage sites are needed to reach climate mitigation goals by 2050. In order to augment the Aurora site and expand CO2 storage in the northern Horda Platform, regional traps and seals must be assessed to better understand the...
Article
Full-text available
The Permian-Triassic alluvial rift succession in the Horda Platform area is analysed to construct a refined depositional model. The study demonstrates how subsurface continental rift successions may be stratigraphically subdivided and correlated by integrating seismic and well-log data in concert with conceptual models. Regional unconformities mark...
Preprint
Full-text available
Discrepancies in models of continental rift-basin dynamics and stratigraphic response calls on further investigation on the subject. Geometric- and lithological trends between stages of faulting is studied in the Permian- Triassic continental rift succession in the Horda Platform. The Horda Platform occupies the northeastern margin of the North Sea...
Conference Paper
The presence of Upper Jurassic through Lower Paleogene sealing units in the Horda Platform has been assessed and established for the purpose of derisking the Alpha CO2 storage prospect in the Smeaheia fault block. The nearby Troll East field closure provides as an excellent analogue for evaluating seals surrounding the Alpha closure. Analysis of ma...
Article
Smeaheia, a prominent fault block located on the Horda Platform, northern North Sea is identified as a potential subsurface CO2 storage site. We utilize the GN1101 3D seismic survey 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 st...
Article
Full-text available
From 2006 through mid-2018 there have been 125 Mw = 2.5 recorded earthquakes within the Fort Worth Basin and the Dallas-Fort Worth metropolitan area. There is general scientific consensus that this increase in seismicity has been induced by increases in pore fluid pressure from waste water injection and from cross-fault pore pressure imbalance due...

NCCS Task 9 - Structural derisking
Article
An understanding of trap and fault seal quality is critical for assessing hydrocarbon prospectivity. To achieve this, modern analytical techniques leverage well data and conventional industry-standard 3D seismic data to evaluate the trap, and any faults displacing the reservoir and top seal intervals. Above all, geological interpretation provides t...

Full-text available
Abstract: Smeaheia, a potential subsurface storage unit situated in the northern North Sea, east of Troll East was previously considered as the most suitable location for storage of CO2 for a proposed full-chain CCS project in Norway. The site was preferable owing to the adjacency to existing pipe-line infrastructure, a lack of potential for interf...
Thesis
Full-text available
Faults that displace siliciclastic reservoirs have been observed to either seal hydrocarbon accumulations in structural traps or serve as conduits for buoyant fluid migration. While many faults located along the Texas Inner Shelf in the Gulf of Mexico do provide adequate lateral seals for the Lower Miocene petroleum system, oil and gas operators ta...

The ambitions for this Task are to reduce risk related to injecting and storing CO2 in the continental shelf, and contribute to maximize the CO2 injection volume for the Smeaheia region (Norwegian Continental Shelf storage region) as well as develop techniques to address fault-sealing and integrity. Task will investigate: - Faults and migration pathways in the Smeaheia region - How to improve geological and geomechanical models for the area - Challenges related to pressure depletion prior to injection - Improved models for along fault flow and fault reactivation - The possibility of additional storage volumes related to satellite storage sites (additional injection wells) in the Smeaheia region https://www.sintef.no/projectweb/nccs/research/structural-derisking/#/
