... Abstract Summary The multi-objective optimization of CO 2 -water-alternating-gas (CO 2 -WAG) injection identifies the optimal well control scheme that co-optimizes NPV and CO 2 storage. Considering the expensive computational cost of the compositional simulation, a popular approach is to use...

... Abstract Carbon capture and storage (CCS) provides a viable option to reduce CO 2 emissions into the atmosphere. In CCS, CO 2 is planned to be safely stored in suitable subsurface formations, providing sufficient storage capacity and sealing integrity. Analysing caprock properties like...

...Fluid Behavior on First Fill Fig. 1 presents the constant enthalpy behavior of first fill from a source of dense phase pure CO 2 at 100 bara and 10°C entering a pipeline at low pressure. As the fluid drops in pressure, the temperature follows the CO 2 phase line, and therefore the CO 2...

... For carbon steel pipelines being used for CO 2 transportation, hydrotesting introduces a series of challenges linked to the post hydrotesting phase where the line must be drained and dried to ensure that all free water is removed. The following sections in this paper outline some elements...

... compression and pumping energy requirements, leading to high OPEX, CAPEX, and CO 2 emission. A novel Pseudo Dry Gas (PDG) concept has been developed as an inline gas-liquid separator (liquid removal system) which separates liquids into a dedicated liquid line from the gas to induce hydraulically ‘dry gas...

... After a short period of time the CO 2 is absorbed onto the material and the system initiates the closure of the inlet and outlet doors. Subsequently, the vacuum pump is engaged to expel any remaining air in the unit. Once this is completed, the heating system is activated to release the absorbed...

... the service life of the pipeline. Internal bore fluid permeation into annulus can happen throughout the life of flexible pipe. As explained, based on actual product composition data, there was presence of H 2 S and CO 2 . It is typical for a hydrocarbon reservoir to produce H 2 S especially when water...

...US Regulatory Guidance on CO₂ Sequestration Area of Review (AoR) and Class VI Permits In the realm of CO 2 sequestration, stringent monitoring techniques are mandated to trace the progression of the CO 2 plume and subsurface pressure changes. Regulatory authorities, operating...

...Caprock Integrity Evaluation Abstract One of the efforts to reduce the impact of climate change is by reducing carbon dioxide (CO 2 ) emission through carbon capture and storage (CCS) operation. As part of CCS feasibility study, geomechanical risk analysis is conducted on the field...

... Note that standard CO 2 saturation curves should be referenced as there are limitations to the statements above due to the various combinations of effects on the cement that can occur, and the effective parameter range (temperature, pressure, salinity) for CO 2 is broader than the scope...

... of the origins of CO2 and its prediction which will help in de risking prospects and monetizing stranded high contaminants fields. This novel method employing an integrated Geology and Geophysics (G&G) coupled with a model-based approach has been utilized to produce CO 2 concentration and risk maps...

... When CO 2 is introduced into the shale, it is held in the macropores structure as free gas ( Fatah et al., 2020 ). The CO 2 -shale interaction occurs inside the nanopores system throughout time, influencing the pore structure and its specific surface area, total pore volume, fractal dimension...

... The savings could be summarized in: Drilling Days including all engines, power generation and all CO 2 emissions associated with the drilling rig. Logistics Days include transportation of chemical products, trucks, and vessels, depending on the working environment. This analysis...

... Project X will be the first Carbon Capture and Storage (CCS) project in Company Y, amongst organization's anchor to achieve net zero emissions by 2050. This project will be the largest offshore CCS project in the world with the ability to capture up to 3.3 MTPA of CO 2 e from new CCS facilities...

... continue to develop a comprehensive connection test protocol for CCS injection wells and investigate impact of low temperature and the corrosion performance of premium OCTG connections with liquid CO 2 . CO 2 phase change can occur in the tubing during the process of injection or during the shut...

.... As the utility and deck space requirements of these CO 2 capture modules are not to be ignored, it is best to consider CCS at the start of a field development project. This paper, however, also describes possible solutions for implementing the CO 2 capture modules on existing offshore facilities. Solvent...

... Abstract The sequestration of carbon dioxide (CO 2 ) in shale formation has dual benefits of reducing carbon emissions and enhanced oil recovery (EOR). CO 2 purified from industrial waste gas is the main gas source for CO 2 injection into oil reservoirs, but industrial waste gas may contain...

... Photocatalytic reduction is a sustainable technology which uses light energy to convert CO 2 into valuable products. For example, UV lamp [ 8 ] and renewable solar [ 9 ] can be used to convert CO 2 into methanol. In a typical photocatalysis reaction, photon energy is used to photoexcite...

...: namely, CO 2 is injected into the stratum to generate CO 2 hydrate, and the surrounding area is heated by the exothermic formation of CO 2 hydrate to promote the dissociation of methane hydrate. This combination of CO 2 hydrate storage and enhanced recovery of methane hydrate is important because...
