“…Here, the negative signs are indicative of profits earned by selling the incremental fuel. However, these costs are subject to wide variability as a function of the effectiveness of CO 2 injection; that is, amount of hydrocarbon recovered per tonne of CO 2 injected 15,63 . For instance, the effectiveness of EOR in the Gulf Coast is 0.9 bbl‐oil/t‐CO 2 , which is significantly lower than the value for California (2.5 bbl‐oil/t‐CO 2 ) 11 .…”

Deployment of bioenergy with CO 2 capture and storage (BECCS) is projected to be crucial in reducing the United States' CO 2 emissions intensity. In this paper, we utilize a spatially explicit costing model to evaluate how regional biophysical factors and geography affect BECCS viability. We find that the cost of biomass provision and CO 2 transport and storage are an average of $20/t-CO 2 and $16/t-CO 2 for aquatic and terrestrial BECCS, respectively. Assuming rapid technological development in the CO 2 capture domain, this corresponds to 40-72% of land area in the conterminous United States exhibiting systems integration costs compatible with 2030 carbon prices (median $90/t-CO 2). Results are strongly influenced by the cost of geologic sequestration, in particular storage quality (as driven by depth, permeability, etc.) and available capacity, rather than simply proximity to nearby CO 2 sources. For this reason, the Southeast presents appealing BECCS readiness owing to high biomass productivity (several counties with yield >100 000 dry ton of biomass per year) interspersed with well-explored sinks with large sequestration potential and optimal reservoir quality with permeability >500 mD. We also find that geologic storage capacity is unlikely to be a major biophysical constraint, as sink utilization in most states would likely remain below 10% at the projected rates of BECCS deployment to achieve the 2°C target and as low as 1% in Texas, Oklahoma, and Alabama. The analysis also reveals subtle secondary outcomes; for example, to what extent different regions may be well poised to adopt different, complementary negative emissions technologies based on specific confluences of circumstances.

“…However, shale gas exploration in India is still at its primitive stages of commercial validity. Although little research on Indian coal deposits pertaining to coal bed methane extraction has been reported, − research on shale properties has been very much limited. , Feasibility of shale gas extraction in India within its economic liability requires immense data to pose shale gas as a safe and reliable alternative to the conventional coal energy. Therefore, research on characterizing the Indian shale reservoirs has become a new prospective research platform.…”

A thorough knowledge on pore size distribution (PSD) is one of the fundamental requirements for characterization of shale gas reservoirs and for accurate estimation of their gas storage potential. However, being an important future source of energy need in India, the pore size distribution of Indian shale gas systems is not scientifically well understood. In the present study, the nanoscale pore size distributions of prospective Indian shale basins, viz., Cambay, Cauvery, Krishna-Godavari (K-G), and Damodar valley (DV), were investigated using mercury injection porosimetry (MIP) and low-pressure gas adsorption (LP-N2 and LP-CO2) techniques. The study focused on identifying the priority basins for shale gas production which can be substituted for sequestration of CO2 based on their PSDs. The samples exhibited higher thermal maturity with increasing organic content. The chemical composition of the shale samples was inferred from XRD data, which depicted higher clay content. The prominent clay minerals identified muscovite, illite, and kaolinite, which are generally flaky in nature. These minerals contributed significantly to the pore size complexity of the studied shale samples. The experimental result suggested that the samples exhibited diversified pore size characteristics. The shales are chiefly bimodal, consisting of mesopores (2–50 nm) and micropores (<2 nm). The micropores were efficiently accessed using CO2, while N2 was effective on characterizing the mesopore region. MIP analysis was used to infer the pore throat area. The average pore diameter of samples ranged from 3.38 nm in Damodar valley to 3.94 nm in thr K-G basin, while Cauvery and Cambay basin samples possessed 3.88 and 3.86 nm, respectively. Both N2 and CO2 adsorption (type II and type I, respectively) suggested the presence of micropore infilling in all of the basin samples. However, Cauvery basin samples were inferred with higher mesopore content as compared to other basins and possessed higher quartz percentage, making it more appropriate for hydraulic fracturing. The Cauvery basin showed enrichment of larger pore sizes. The results signified that the Damodar valley shales have a higher affinity toward CO2 adsorption. This suggested that the basin could be a better host for future carbon storage, compared to other basin pore structures.
