Calcium carbonate is by far the most widespread scaling material. Its deposition in pipes andflowlines has been along-standing problem for many industries. Hence, a lot of research is devoted to scale inhibition. One of thecalcium carbonate scale management methods relies on removal of calcium ions ...

Depleted oil reservoirs are considered a viable solution to the global challenge of CO₂ storage. A key concern is whether the wells can be suitably sealed with cement to hinder the escape of CO₂. Under reservoir conditions, CO₂ is in its supercritical state, and the high pressures and temperatures i...

The key objective of well cementing has always been to provide zonal isolation in oil, gas, and carbon dioxide (CO₂) storage wells to ensure safety and prevent environmental problems. The loss of zonal isolation and wellbore failures are mostly associated with inappropriate cementing and/or cement-s...

In this study, our recent and new approach for detailed tracking of the interface between well fluid and cement by using particles is investigated. The particles can enable us to know the precise location of the interface between two fluids and be sure about displacement efficiency in the annulus. T...

In this study, a new approach for detailed tracking of the interface between well fluid and cement by using particles is investigated. This can improve the quality of annular cementing of CO₂ wells and thus the storage safety. For this purpose, the displacement mechanisms of Newtonian and non-Newton...

Clay‐rich shale poses substantial challenges to establishing well integrity during drilling, operation and abandonment of wells used in oil and gas production, CO₂ sequestration, and other waste disposal activities. We review problems created by shale for borehole stability, zonal isolation, and lon...
