Development and evaluation of a coaxial cable sensing system for CO₂ sequestration wellbore integrity monitoring
… sensing system for monitoring and evaluation of wellbore stability during CO<sub>2</sub> injection.</p> <p>The real-time distributed sensing system is composed of Fabry-Perot interferometer based coaxial cable temperature and strain sensors. A high pressure high temperature (HPHT) sensor testing …

Emergence of Delamination Fractures around Casing and Its Stability
The cement sheath failures and nearby wellbore failures may lead to upward flow of drilling fluid or formation fluid, which may have significantly adverse consequences like loss of reserve and environmental hazards. In order to maintain wellbore integrity in the long term, it is expedient to …

Geomechanical characterizations and correlations to reduce uncertainties of carbonate reservoir analysis
… that examines the uncertainty of carbonate wellbore integrity.</p><p>The results present a new engineering classification to evaluate the carbonate drillability and deformability. Additional developments regarding the relationships between the carbonate compressive strength and confining …

Wellbore Microannulus Characterization and Seal Repair: Computational and Lab Scale Modeling
… Carbon Capture and Storage (CCS). Pre-existing wellbores penetrate the reservoirs where supercritical CO2 is to be injected. These wellbores can potentially be a pathway for contamination if CO2 leaks through wellbore flaws to an overlying aquifer or the atmosphere. Characterizing wellbore …

Effects of filtration process variables on filter cake properties and formation
… techniques have been developed to increase the integrity of the wellbore, stop lost circulation and allow drilling with wellbore pressure in excess of the fracture gradient. These techniques are theorized to alter the stress at the wellbore in order to make it more difficult to open or propagate …
