Well Cement Degradation and Wellbore Integrity in Geological 2 CO$_2$ Storages: A Literature Review

Carbon capture and storage has emerged as the most cost-effective way to minimize the CO _2 ratio in the atmosphere. The well cement degradation and wellbore integrity of well cement storage must be investigated thoroughly in order to ensure a safe and economical geological storage. This review paper is intended to give the researchers a fundamental understanding of well cement degradation and wellbore integrity in geological CO2 storages to assist them in further investigation. In experiments and simulations during geological CO _2 storage, the paper mainly focuses on mechanical, thermal, chemical, and degradation time for cement.

Accelerated Accumulation of Anthropogenic CO 2 Drives Rapid Acidification in the North Pacific Subtropical Mode Water During 1993-2020

According to recent reports, the formation and movement of the North Pacific subtropical mode water may play a significant role in oceanic uptake, transport, and storage of anthropogenic CO 2. Moreover, tracer-based studies reveal that the accelerated accumulation of C ANT could be traced back to the surface formation waters by STMW formation. mode waters' memory function in retaining the anthropogenic carbon fingerprint during its formation and transport have been shown by the vertical and horizontal consistencyencies.

Multi-Layered Systems for Permanent Geologic Storage of CO 2 at the Gigatonne Scale

Carbon Capture and Storage as an essential decarbonization solution depends on a fine-grained caprock's sealing capacity to permanently store CO 2 deep underground. Uncertainties in estimating the caprock sealing capacity are on the rise on both spatial and temporal scales, and they could delay CCS deployment at the gigatonne scale. We have created a computationally useful transport model to capture the trend of basin-wide rise CO 2 migration in a multi-layered environment with geological time scales.

Applicability of the linearized Poisson-Boltzmann theory to contact angle problems and application to the carbon dioxide-brine-solid systems

The linear Poisson Boltzmann equation has been extensively used in colloidal science and bioelectrostatics for the determination of potential and surface charge density. Low pH conditions that conform to LPB theory result in low pH values in the case of carbon dioxide sequestration in saline aquifers under extremely low pH conditions coupled with adsorption-induced decrease of surface charge density. Using literature based experimental results, we discovered the point of zero charge pH of sandstone, quartz, and mica when integrated into our model. Our original research focuses on interparticle electrostatics involving colloidal stabilization, which is quite different from the classical model, because we have used the LPB theory in a completely different context from the classical approach, where the focus is on colloidal stabilization involving colloidal stabilization.

Fusarium head blight resistance exacerbates nutritional loss of wheat grain at elevated CO 2

At ambient and elevated CO 2, 15 wheat cultivars with varying degrees of resistance to Fusarium Head Blight were grown at ambient and elevated CO 2 to determine how disease resistance traits could influence wheat climate resilience. Although most wheat cultivars had increased yield when grown at elevated CO 2 levels, FHB moderately resistant cultivars' nutritional values were more affected than susceptible cultivars. In reaction to elevated CO 2 exposure, this is the first report showing a connection between the degree of plant pathogen resistance and grain nutritional content loss in response to elevated CO 2.

Radon signature of CO 2 flux constrains the depth of degassing: Furnas volcano (Azores, Portugal) versus Syabru-Bensi (Nepal Himalayas)

Here's a look at how the depth of degassing at two hydrothermal sites in geodynamically active contexts, Furnas Lake Fumarolic Field with mantellic and volcano-magmatic CO 2, and the Syabru-Bensi Hydrothermal System with metamorphic CO 2, are limited by combined measurements. At both sites, radon fluxes reach extremely high levels that are systematically associated with large CO 2 fluxes. An advective-diffusive model of radon transport is well represented by a comprehensive investigation of radon sources.
