Depleted hydrocarbon reservoirs are a promising target for CO 2 sequestration. Injection of
cold CO 2 into such geological reservoirs will cause thermal stresses and strains in wellbore …

The cement sheath, serving as the primary element of well barriers, plays a crucial role in
maintaining zonal isolation, protecting the casing from corrosion, and providing mechanical …

Leakage is one of the most serious challenges for the safe production of high‐pressure gas
wells for its high risks, including abnormal annular pressure, natural gas accumulation, and …

Salt cavern used for energy (natural gas, hydrogen) storage has a significant advantage in
peak shaving of gas supply due to their high injection-production efficiency and fast gas …

Rock salt cavities are commonly utilized for underground gas energy storage on a big scale
due to their characteristics of low permeability and low porosity. Salt cavern wellbore leaks …

Due to their good air tightness and stability, gas storage salt caverns are widely used in
rapid peak shaving of natural gas. The wellbore is used to connect the cavern to the surface …

Portland cement is commonly used in everything from general construction to fluid barriers
in environmental and petroleum structures. Wellbore integrity finite element models have …

Cement sheaths undergo extreme loading conditions in wells during subsurface operations.
A damaged cement sheath may lead to fluid communication between different formation …

Well integrity represents an objective/solution for protecting human life and environment
while retaining oil production rate during the life of the well. Characterization of cement …
