Alkali-activated materials, sometimes called geopolymers, can be used as alternative
cementitious materials to conventional Portland cement. Currently, there is a significant …

This paper presents the results of numerical studies aiming to assess the effects of cement
hydration on the casing integrity in superhot well conditions. Casing integrity challenges for …

Well integrity issues have been widely studied in the oil and gas sector; however, with
storage wells (eg towards natural gas, CO2 and H2), new challenges may arise due to the …

Cement sheath plays important role for the integrity of injection/production wells in
subsurface activities. During the life of the well, mechanical and thermal loadings are …

The strength of Portland cement material deteriorates sharply in the high-temperature
environment under the shale oil in-situ conversion condition, which can reach up to 650 C …
