“…To date, CCS deployment has been restricted locations known as extensional basins where tectonic plates are stretching, as these are characterised by low background seismicity. However, widespread storage will require a wider range of settings including locations that are not hydrocarbon bearing and where geological data is sparse (Sun et al, 2020(Sun et al, , 2021.…”

Limiting climate change to less than 1.5 o C would require vast quantities of CO2 storage in subsurface geological formations. Global injection rates projected by integrated assessment models synthesised in IPCC reports are on the order of ten gigatonnes per year by 2050. Industrial experience with megatonne per year storage projects allows us to evaluate the feasibility and potential limitations of a transition to the gigatonne scale. The successes with CO2 have also led to interest in new energy technologies using subsurface fluids, including hydrogen storage underground. We review the role of subsurface CO2 and H2 storage in a sustainable energy transition. We have found that current deployment demonstrates the viability of CO2 storage in a variety of geological, social, economic, and technological contexts, and is making contributions to climate change mitigation today commensurate with the impact of solar photovoltaics in the USA market. The implications of this are that CO2 storage is well positioned to play an important role in the energy transition, and H2 storage may benefit from this experience. However, these are not certain outcomes, with many hurdles -the development of multi-site regional scale storage, viable business models for accelerated deployment, demonstrating environmental sustainability and achieving societal acceptability -yet to be addressed.

“…Foreland basins and their adjacent fold-and-thrust belts contain significant hydrocarbon resources (Mann et al, 2003), and also show high potential for CO 2 storage (Sun et al, 2020). As important fluid migration pathways and potential reservoir space, fracture networks have been widely studied in thrust belts composed of carbonate deposits due to their abundant hydrocarbon resources, e.g., in the Zagros fold-and-thrust belt (Stephenson et al, 2007), the Bighorn Basin (Bellahsen et al, 2006), the Apennines (Van Dijk et al, 2000) and the Oman Mountains (Gomez-Rivas et al, 2014).…”

Sedimentary rocks of foreland fold-and-thrust belts typically undergo intensive fracturing as fold grows. The resulting fracture networks can present significant variations depending on the distribution of sedimentary facies and the complex structural characteristics of fold-and-thrust belts. The Puig-reig anticline, located in the south-eastern Pyrenees, mainly exposes proximal fluvial deposits in the north limb and medial fluvial deposits in the rest of the anticline. Thus, this anticline constitutes an excellent case study to investigate the main controls on the distribution of fracture networks in folded fluvial deposits, in terms of structural position and lithofacies variations. Outcrops were selected to be representative of different structural positions, from the fold hinge to its limbs, and of a variety of the main lithofacies, from proximal to medial fluvial deposits. Fracture data were acquired using the linear scanline method. Results indicate that the anticline is affected by four sets of fractures. The north limb is dominated by thick conglomerate bodies with interlayered sandstones deposited from unconfined flash floods and wide-shallow channel streams in the proximal fluvial fan, and presents large fracture spacing and low fracture intensity but relatively large fracture length and aperture. The crest and the crest-limb transition zones are mainly composed of interlayered conglomerates, sandstones, siltstones and clays, deposited from braided channel streams and overbanks in the medial fluvial fan and present fractures with relatively high fracture intensity and variable fracture length and aperture. The south limb, composed of channel filling sandstone layers and stable overbank fine deposits in the medial fluvial fan, is characterised by low fracture intensity and small fracture length and aperture. Based on multiple linear regression analysis, fracture intensity is mainly controlled by the structural position, bedding thickness and lithological associations, with relatively more intense fracturing in thin sandstone layers with multiple interlayers of fine deposits in the anticline crest. The fracture length is mainly controlled by bedding thickness 2 and is affected lithological associations. The fracture apertures are mainly controlled by lithofacies, with relatively higher apertures affecting conglomerate bodies. The results of this study are relevant for characterising similar systems in the subsurface, where data is scarce.

“…For example, in the South Pyrenees, an ideal natural laboratory due to its well‐preserved and well‐exposed outcrops, most studies focused on the cover thrust sheets (Travé et al ., 1997; Lacroix et al ., 2011, 2014, 2018; Beaudoin et al ., 2015; Crognier et al ., 2018; Cruset et al ., 2018, 2020a,b; Nardini et al ., 2019; Muñoz‐López et al ., 2020a,b), whereas only a few studies involved the Ebro Foreland Basin (Travé et al ., 2000, 2007; Cruset et al ., 2016). On the other hand, compressional settings have high potential for carbon capture and storage (CCS) (Sun et al ., 2020). The Ebro Foreland Basin has been assessed as one of the priority regions for CCS development in Spain (Sun et al ., 2021a).…”

Origin and distribution of calcite cements in a folded fluvial succession: The Puig‐reig anticline (south‐eastern Pyrenees)

As one of the predominant diagenetic products in clastic rocks, calcite cements are typical fingerprints of cement‐forming fluids and are key controls on reservoir quality. The Puig‐reig anticline, in the south‐eastern Pyrenees (Spain), exposes excellent outcrops of conglomerates, sandstones and claystones, which were deposited from a proximal to medial fluvial system and underwent folding, fracturing and cementation. This anticline constitutes an appropriate case study to investigate the origin and distribution of calcite cements during folding evolution and how they affect reservoir quality. Based on structural, petrographic and geochemical analyses (carbon, oxygen, strontium and clumped isotopes and elemental composition), five generations of calcite cements (‘Cc0’ to ‘Cc4’) have been identified, filling intergranular porosity of host rocks, faults and four fracture sets (F1 to F4). Calcite cement Cc0 precipitated in intergranular porosity from meteoric fluids in the phreatic zone during the early diagenetic stage. During the most intense phase of thrusting and folding, Cc1 precipitated in intergranular porosity, faults and F1 to F4 fracture sets from hydrothermal fluids that migrated from deeper areas of the Pyrenean chain. During the late stage of fold growth, Cc2 precipitated in faults and their associated fractures in the anticline crest from hydrothermal fluids but at shallower burial depths than that of Cc1. Calcite cement Cc3 mainly precipitated in fractures with the same strike as F1 and F4 fracture sets in the north‐western part of the anticline, from formation fluids that probably migrated through the frontal thrust of the south‐eastern Pyrenees. During the continuous fold denudation, Cc4 precipitated from meteoric fluids in F1 to F4 fracture sets across the anticline. Results indicate that at foreland basin margins, external fluids coeval with compressional deformation and/or alteration of detrital carbonates contribute to intensive calcite cementation. This can result in an overall occlusion of porosity and significantly damaged reservoir quality.
