DOI: 10.1016/j.ijggc.2019.102896
Abstract: Abstract CO2 leakage through damaged wellbore cement sheaths is a major risk of geologic CO2 storage (GCS), as conventional wellbore cement is brittle and can be damaged due to acid attack and downhole stresses during… read more here.

DOI: 10.1021/acsomega.2c00903
Abstract: During hydrate exploitation, the formation and decomposition of hydrate in the wellbore are affected by many factors such as salinity, temperature, pressure, gas–liquid ratio, and so on. In the drilling process, inhibitors will be added… read more here.

DOI: 10.2118/195573-pa
Abstract: With oil and gas wells extending deeper and deeper, downhole conditions become increasingly complicated, and thus increasingly sophisticated wellbore models are needed. Current wellbore models usually neglect the coupling effect in the cement–consolidation process and… read more here.
