SCIN

Oceanit’s SCIN (Steel Cement Interfacial Nanobond) technology is a nanotechnology-based pipe treatment that achieves significant improvement in the water-wettability of oil well casing exteriors to provide a significant increase in cement-steel bond strength and uniform cement-steel bond. SCIN-treated steel was rigorously laboratory tested, scaled up in two different locations, and subjected to field trials in both unconventional and deepwater applications.

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 both unconventional and deepwater environments. The pipe treatment was applied to over 5,200 feet of pipe, ranging from a 5-inch 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.

  • Creates a permanent, superhydrophilic surface
  • Increases interfacial bond between steel and cement
  • Improvement in acoustic cement evaluation
  • Highly scalable process suitable for steel tubulars, valves, and components
  • Excellent high-pressure, high-temperature stability
  • No changes required to normal pipe handling equipment or procedures
