Cement is a major material component in the construction and sealing of hydrocarbon wells.
Well leakage through cement is a problem that increases maintenance costs and poses …

Durability and long-term integrity of oil well cement are the most important parameters to be
considered while designing the cement slurry, especially in the high-pressure and high …

The cement paste is subjected to various loads throughout a well's life, which may
compromise some of its essential characteristics and impair its performance. When the …

Oil well cement is a type of natural brittle material that cannot be used directly in cementing
operations. Fiber is a type of material that can effectively improve the strength and …

In deeper wells, high pressure and temperature post cementing operations put extreme
stresses on the cement sheath and dramatically affect the cement integrity. So, the design of …

To attain cement sheath integrity, a tight and ductile microstructure for the cement matrix is
desirable. Despite improvements achieved in cement design by employing fiber additives …

Stress‐induced fractures in wellbore cement can form high‐risk pathways for methane or
carbon dioxide leakage, yet little to no quantitative information on the impact of these …

The foremost function of primary cementing is to achieve zonal isolation and ensure long-
term cement integrity during the lifetime of the well. Current advanced drilling and cementing …

Mechanical performance of cement significantly affects cement sheath integrity and long-
term zonal isolation, especially in complex high-temperature, high-pressure (HTHP) wells …

Gas migration, one of the primary problems related to the integrity of oil wells, is caused by
cement failures. Gas migration can result in costly well repairs and may endanger personal …
