Downhole Tools

hydrobur-service, llc, manufacturer of downhole drilling equipment
  • About Company

    At Hydrobur-service we offer a broad portfolio of downhole drilling tools to optimize drilling for maximum efficiency and cost savings.

    We develop, manufacture and market a wide range of downhole tools to address the most complex challenges of steering a well and to provide high performance drilling and trajectory control.

    The company invests into research, development and manufacturing of its own innovative and cost-effective technology products, which forms the basis of our competitive advantage. Our in-house engineering team pushes the boundaries to design, improve and deliver new patented PDM power sections, double-acting hydraulic drilling jars, fishing jars, circulation subs, weight-on-bit tools and other drilling tools for today’s cost-conscious market.

    Drill Safer. Prevent Lost in Hole.


    The Hydrobur-service jar is designed to free a drilling tool stuck in a hole by jarring against the stuck point.

    Our drilling jar is a double acting hydraulic jar designed for use during drilling operations to apply an intensified force against a stuck portion of the drill string by jarring either up or down.

    Our fishing jar is a hydraulic jar designed to free a stuck portion of the drill string by applying an impact force during fishing operations by jarring up and delivering upward impact force with a higher frequency than a drilling jar due to a faster recharge.

    Our double acting hydraulic drilling jars and hydraulic fishing jars have a set of featured standardized assembly components that allow for the assembly of either of the models while manufacturing.


    • Simple, robust and dual-use design
    • One set of spare parts and accessories
    • Drilling or fishing assembly manufacturing depending on operational needs and requirements
    • Order-to-shipment time saving

    Optimize Performance. Maximize Efficiency.

    Multiple Activation Bypass Systems

    Our patented circulating sub is designed to protect the downstream BHA components by directing the flow from the inside of the drill string to the annulus while circulation.

    Weight-on-Bit Tool

    Our patented Weight-on-Bit Tool is designed to ensure even axial load, to prevent shock and vibration. It does not create any differential pressure, thus, causing no overpressure to mud pumps.

    Drilling Shock Tools

    Our drilling shock tool reduces direct impact on the drill bit, vibration in the BHA and harmonics in the drill string while drilling. A robust mechanism lessens vibrations and extends bit life.


    Our dump valve allows the mud to fill or drain from the drill string while tripping. Dump valve is made up above the positive displacement motor.

    Our float valve is designed to avoid flow of drilling fluid from the annulus to the drill string via BHA elements. Float valve is made up above the positive displacement mud motor.


    Our downhole filters are protective mechanisms that are installed above positive displacement mud motors to prevent PDM from clogging up with debris.
