Nano Sealants for Oil & Gas wells

Global warming is one of the major issues in worldwide. Methane emission plays critical role, oil & gas wells emit tones of methane in environment through leakage every year. It is very important to seal the micro cracks within the wells to stop methane emission to save the environment.


VSI has been serving in Oil and Gas field for last two decades. We are always passionate to provide best possible Engineered, Time saving and Economical solutions in Oil & Gas sector.

We design innovative sealants   and adhesives along with the engineering to solve leaks in the most challenging conditions. Our sealants are developed with superior durability characteristics and penetration characteristics to meet the most stringent performance requirements. Sealants and adhesives that can function under a wide range of temperature, pressure and chemical exposure conditions.

    TSN-20 Subsurface Sealer

    TSN-20 is a subsurface sealant that penetrates, flows and seals very thin microcracks (< 30 micrometers). These cracks are large enough to be problematic but so small that other sealants cannot penetrate and seal.

    • The set-time, density, and viscosity are tailored to provide project-specific solutions.
    • Sets under brine and maintains flowability for up to two hours.
    • Maintains favorable properties to temperatures over 100 oC, making it applicable to deep oil & gas wells and even some geothermal wells.
    • Bonds well to a wide range of surfaces, including steel, concrete and rock.
    • Withstands a high number of pressure and temperature cycles due to its flexibility, strength and long-term durability.
    • Very durable under a range of environmental conditions.

    Microfine Cement

    Contact angle for a type G cement substrate and a drop height of 10 mm for TS-Nano 20™ and microfine cement.

    The contact angle for TS-Nano 20™ is 62% lower than the contact angle of microfine cement. The surface tension is 43% lower than the one of the microfine cement. Contact angle, viscosity, and surface tension are indicators of sealant penetrability and its ability to flow into thin microcrack and displace other fluids

    TS-Nano sealant TSN-20 has much greater bond strength to cement and rock formations than microfine cement
