New Approach Tests Cement-Sheath Integrity During Thermal Cycling
Operators in the North Sea have been concerned about the ability of the cement sheath to maintain sealing integrity because of the increasing number of reported failures in mature wells. This paper presents results from a new laboratory setup to visualize the source of issues.
An Integrated Approach to Solving Sustained Casing Pressure in the Cana-Woodford Shale
Many wells in the Cana-Woodford shale suffer from chronic sustained casing pressure (SCP) because of poor cement-sheath bonding.
