DAS continues to be a promising and cost-effective technology for carbon storage monitoring applications including systems that monitor geological changes using active seismics, and also for passive mode operations, e.g. the monitoring of microseismic activity during CO2 injection. The authors have developed a DAS interrogator research platform that has enabled a better understanding of the critical equipment architecture and experimental factors influencing the collection and analysis of DAS data. The authors plan to test this at different CCS pilot installations. In the future, the performance and functionality of the DAS interrogator research platform will be expanded, and techniques for applying it developed further in order to meet CCS specific needs determined from wider collaboration.

To evaluate subsurface reservoirs for CO2 sequestration, the grain scale properties and role of diagenesis is important for the injectivity and the subsequent mobilization. This study focuses on Johansen Formation of Jurassic age in the vicinity of Troll field within the northern North Sea. Johansen Formation is a saline aquifer and no hydrocarbon discovery has been reported in this reservoir so far. We analysed 24 wells using petrophysics and rock physics techniques to obtain net reservoir, net to gross ratio, effective porosity, volume of shale and level of cementation, and attempted to relate these parameters with the factors influencing them. The reservoir properties were found to be optimal approximately around depths shallower than 2000m (below sea floor, BSF). Even the shallowest sandstones exhibited cementation indicating calcite precipitation while the sediments deposited. Presence of shale however found to inhibit the quartz cementation possibly preserving the porosity. These findings will help understanding the complexity of the Johansen Sandstone as storage reservoir and the influence of heterogeneity on CO2 migration.

A re-establishment of the Svelvik Field Laboratory for active CO2 migration monitoring is accompanied with numerical pre-injection site investigations using a poro-elastic description of the glacio-fluvial and marine deposits. The aim is to discriminate pressure and saturation effects of CO2 injection and provide an optimized layout for a multi-physical monitoring campaign. Near surface and appraisal well grain size analysis and appraisal well logging data are used to constrain the elastic properties of a forward model. Results of the previous monitoring campaign and simulation for the planned injection are used to design the layout of the individual monitoring technologies optimized for a range of plume migration scenarios. The monitoring campaign and observation well locations are designed such that the CO2 plume will be captured by cross-well data. The simulated gas saturations and pressures are used to obtain elastic parameters describing the acoustic response. Using worst to best case scenarios being based of rock physical parameters provide resulting sensitivities to particular conformance criteria.

In July 2018, the Ministry of Petroleum and Energy (MPE) offered an area in the northern Stord Basin for applications to exploit a subsea reservoir for injection and storage of CO₂. This will be the first licence regulated by the Norwegian regulation for CO2 Storage (2014). By offering the area south of the Troll Field for an exploitation licence, it was decided to continue with the qualification of the Johansen-Cook aquifer for the Northern Light project.

Gassnova is working to establish what could become Europe's first industrial CCS project. The project will demonstrate that carbon capture, transport and storage (abbreviated to CCS) is possible and safe to implement. A full-scale CCS project can provide lessons and experiences that new CCS projects can take advantage of. In this abstract we present some experiences from the maturation of storage sites on the NCS.

Summary The central objective of this paper is to study the balance and interactions of the different mechanistic contributions to the physics occurring during oil displacement by CO2 (both continuous and WAG). Mechanism 1 (M1) is the conventional oil stripping/compositional effect and Mechanism 2 (M2) is the near-miscible IFT effect on oil relative permeability through enhanced layer flow. Using sufficiently fine-scale models, we explain how these mechanisms interact with each other and affect the sweep and local displacement efficiency in a heterogeneous permeability field. We believe that studying the key processes separately leads to a greater insight into the physics of CO2 displacement, and this will help us to simulate the transition from immiscible to miscible displacement consistently at larger scales.

Summary Carbon Capture and Storage (CCS) is a key climate mitigation technology required to meet the Paris Agreement goal of limiting global warming. Commercial-scale demonstration projects such as the Quest project in Alberta, Canada, or the Illinois Basin-Decatur project in Illinois, USA, have shown that the technology is feasible and safe. These projects demonstrate that existing technologies are sufficient for the successful implementation of CCS at the mega-tonne/year scale. However, scaling these technologies to meet the future need for giga-tonne/year storage remains a shared industry challenge. Responding to it demands addressing the low-probability, high-impact storage risks that cannot always be avoided within a large and diverse portfolio of CO2 storage projects. These include the risk of induced seismicity and fault reactivation, pressure management to improve storage security, exposure to legacy wells, and lowering the cost of large-scale containment monitoring. We propose four technology development pathways to address these giga-ton/year challenges, highlighting key focus areas.

Summary We present an integrated methodology for quantitative CO2 monitoring using Bayesian formulation. A first step consists in full-waveform inversion and CSEM inversion solved with gradient-based inverse methods. Uncertainty assessment is then carried out using a posteriori covariance matrix analysis to derive velocity and resistivity maps with uncertainty. Then, rock physics inversion is done with semi-global optimisation methodology and uncertainty is propagated with Bayesian formulation to quantify the reliability of the final CO2 saturation estimates.

Summary In 2016, a study identified the Smeaheia area located 30km off the western coast of Norway, as a suitable storage site for CO2. A concept selection study requested by the Gassnova public enterprise was subsequently performed by the Northern Lights subsurface team, a group comprised of personnel from Equinor and partners. The study revealed challenges with the various geological structures planned for CO2 storage, as well as the importance of understanding the pressure connectivity with the neighbouring hydrocarbon producing Troll field. Due to these challenges Smeaheia was not found mature enough for concept selection at this stage
