TS-NANO SEALANTS PERFORMANCE
Backed by decades of experience in nanomaterial sciences and sub-surface engineering, TS-Nano patented its sealants that provide sealing solutions to site-specific, complex field problems.
NANO-MODIFIED POLYMER CEMENT
TS-Nano sealants are designed to mix with cement to produce next-generation slurries with superior sub-surface performance.
Core Features
Field Deployment Cases

Case #1
Cut and Capped Well
This well’s wellhead was already removed and the site was remediated. Sometime later, the well started to bring water and gas up to the surface. Cement and other materials were applied to re-plug the well, but gases were still detected at the surface.
TS-Nano Solutions
By working with the well owner, a “saucer” was welded to the cut casing, and TS-Nano’s very flowable sealant was applied over the top of the exposed casing annulus and the cement. Our sealant was able to penetrate the cement porosity and sealed the micro-annuli. The gas leak was successfully shut off.

Case #2
Cut Production Casing With Leaking Cement Plug
This Permian Basin well needed to be Plugged and Abandoned due to mechanical issues. The 5.5-inch production casing was cut and pulled just above a leaking cement plug, leaving a 36ft (~11m) open hole section below the surface casing shoe to place a plug.
TS-Nano Solutions
With such a large volume void, TS-Nano nano-modified polymer sealant was mixed with cement and the modified cement slurry was pumped downhole to the target depth of 400 ft (122 m). The cement plug mixed with TS-Nano sealant successfully passed the regulatory test. This operation allows the well owner to continue filling the wellbore with cement to the surface and complete the entire Plug & Abandon operations.

Case #3
Sustained Casing Pressure (Surface Casing Vent Flow)
This Permian Basin well had cement plugs set at various depths throughout the 7-inch production casing. Previous attempts to mitigate the sustained casing pressure were unsuccessful.
TS-Nano Solutions
TS-Nano collaborated with the well owner to identify poor cement bonds between the surface and production casing strings. To eliminate cement shrinkage and improve cement properties, TS-nano nano-modified polymer sealant with mixed with the cement and pumped down the wellbore. After the operations, the well sustained casing pressure diminished and the owner was able to P&A in compliance with local regulatory requirements.
