Geological storage of CO2 in depleted oil and gas reservoirs is approved due to its
advantages, such as strong storage capacity, good sealing performance, and complete …

Oil well cement is a necessary sealing material for carbon dioxide storage wells and oil and
gas wells containing carbon dioxide, but it is easily corroded by carbon dioxide fluids. Due to …

It is generally recognized that the CO 2 dissolved in formation water poses a serious threat
to the cement sheath in oil and gas wells. A numerical model was developed in this study to …

During the well completion test of deepwater high temperature and high pressure (HTHP)
gas well, the force on the packer changes dramatically, leading to the packer failure and …

Fine particle motions have significant implications in porous media, manifesting in various
natural phenomena and industrial applications. The movement of particles can lead to …

It is one of the important technical difficulties to improve the cementing sealing capacity of
the carbon dioxide (CO 2) injection well for ensuring the long-term effective of the CO 2 …

Cement sheath integrity is a critical concern in the successful implementation of geologic
carbon capture and storage (CCS) projects. Conventional ordinary Portland cement (OPC) …

Wells drilled in carbon storage sites could be converted to potential leakage pathways in the
presence of CO 2-bearing fluids and under the impact of the changes occurring in …

Carbon capture and storage is considered as an amelioration technique to address the
increasing level of carbon dioxide in the atmosphere. Depleted oil and gas reservoirs are …

Multi-packer completion strings have played a pivotal role in secure exploitation of oil and
gas, increasing production and mitigating greenhouse gas emissions. While the integration …
