Traditional well cement barriers often fail over time
Leaks from wells with failed cement barriers are a common problem at all stages of a well’s lifecycle. These leaks, principally comprised of methane, pose operational and safety hazards, can contaminate water-bearing zones, and introduce potent greenhouse gas into the atmosphere.
Stopping a well from leaking can be challenging and costly, often requiring multiple attempts to solve the problem.
Well Operators need new durable permanent barrier technology to stop gas migration, methane emissions, and repeated well repairs.
Polymers are long-chain molecules used in countless materials including sealants. Conventional polymers may have limitations such as low strength, poor thermal stability, and/or limited barrier resistance.
Nanoparticles are materials with dimensions typically between 1 and 100 nanometers. At this scale, they have a very large surface area relative to their volume, and their atoms are highly reactive at a chemical level.
Nanomodification is the purposeful dispersion of select nanoparticles into a polymer to radically improve its properties.
Nanoparticles act like reinforcements that hold the polymer chains together.
Nanoparticles slow down the polymer’s chain motion.
Nanomodification creates a more torturous path and rapidly blocks the gas travel passage.
Nanoparticles activate new surface chemistry and improve adhesion to casing, cement, and rock surfaces.
A product family designed for cement enhancement, well top penetration, and standalone sealing applications.
