Kureha Energy Solutions is an oilfield service company specialized in degradable technology. Kureha has a degradable frac plug product line that differentiates itself from your typical supplier. With KES stemming from a chemical company, it has a vast knowledge of degradables, particularly Polyglycolic Acid or PGA, which is a polymer based degradable. Our degradable frac plugs primarily consist of this material (PGA), which makes us the primary source for non-chloride dependent degradables, meaning our plugs degrade solely with temperature.

    • Comprised of Kuredux PGA polymer which degrades without any trigger, such as acid or salt.
    • Degrades predictably at wide temperature range.
    • More trustable and predictable degradability compared with metal balls.
    • Available diameter from 0.5 inch to 4.5 inch.
    • Specific gravity is approximately 1.6.
    • Environmental friendly fully compostable material, satisfying the test protocols of ASTM D6400 and ISO 14855.
  • Kureha Degradable Rubber (KDR)
    This product has been widely used as the degradable sealing element and temporary protector for downhole tools....

    • High (H), standard (M), low (L), and ultra-low (U) temperature grades are available.
    • Higher mechanical strength than conventional nitrile rubbers.
    • Stably degrades in fluids without trigger (such as acid or salt).
    • Various shapes and hardness are available for your application.
    • Similar deformation behavior with conventional nitrile rubber.
    • Greater elongation at fracture than nitrile rubber.
  • Retrievable Ball Sensor (under development)
    This product enables to gather various downhole information such as temperature and pressure during drilling, completion, and production. A game-changing technology that may eliminate an expensive fiber optic installation or wireline-type sensors....

    • Features

    • Ball sensor consist non-degradable sensor body and dissolvable shell.
    • Ball sensor can be efficiently pumped down hole with the high-density dissolvable shell and can be easily retrieved by flow-back after the high-density shell has dissolved.
    • Low apparent specific gravity (<1.0) after shell dissolves.
    • Collect temperature and pressure information for up to 10 days.
    • Data stored in memory and downloaded to PC at surface.
    • No wireline or coiled tubing units are required.
    • Typical pump-down ball size are 2", 2.5" 2.75".
    • Can be used with frac plugs and other completion tools.
