Significance of nanosilica incorporation in type G oil well cement pastes
… brought about a requisite for improving existing oil well cementing materials and understanding the macro and microstructural characterization mechanisms of oil well cement (OWC). OWC slurries have stringent performance requirements, including low viscosity, rapid strength development, low …

Characterizing the Behavior of Smart Oil Well Cement for Enhancing the Monitoring of Cement Sheath Integrity
Oil well cementing is one of the most important and yet complex steps of a drilling project. One of the challenges in maintaining the well integrity is in monitoring the performance of oil well cement (OWC) used in the construction of the well. Recent oil well failures have clearly identified the …

Reactive MgO and Self-healing Microcapsules for Enhanced Well Cement Performance
The annular cement sheath plays a crucial role in ensuring well integrity by providing adequate zonal isolation, stabilizing the formation, and protecting the casing from corrosion. A majority of well integrity problems originate from oil well cement shrinkage and shrinkage-induced cracking, as …

Modeling the Behavior of Smart Oil Well Cements and Offshore Pipe-Soil Interaction in Very Soft Soil
It is critical to ensure the durability of the oil and gas production infrastructures from borehole to pipelines. Rheology properties and hardening characteristics are some of the important parameters for cementing slurry during installation. Also over the last decade, health monitoring of the …

A nanochemomechanical investigation of carbonated cement paste
… and in particular its principal component, cement paste, has an interesting relation with carbon dioxide. Concrete is a carbon dioxide generator-- it is estimated that 5-10% of atmospheric CO₂ comes from this source. Carbon dioxide is a concrete corroder-- it can penetrate into the porous …

Resistivity Characterization and Modeling of Synthetic Based Drilling Fluids and Corrosion Detection in Steel
… relationship. The model predictions agree well with the experiments results. Also, the effects of various types of contamination on the SBF were investigated. The effects of synthetic based drilling fluids (SBF) contamination on the smart cement with a water-to-cement ratio of 0.38 were …
