For several decades, techniques for modifying the surface of steel pipes were practiced with varying results. In addition, these methods did not address either the hydrophobicity of the carbon steel or steel/cement interfacial bond, other than the use of surfactants in spacers and cement slurry. SCIN offers an economical solution to this issue by achieving a superhydrophilic pipe surface that is chemically reactive to Portland cement, allowing an effective bond to cement.
Working with a major operator, Oceanit has successfully ﬁeld tested SCIN in multiple wells in both unconventional and deepwater environments. The pipe treatment was applied to pipe ranging from 5- to 16-inch diameter. Post-job cement evaluation logs by a variety of techniques demonstrate a consistent improvement in acoustic coupling between the casing and cement.
