Oil and gas extraction

For efficient oil and gas extraction

Oil and gas still make a critical contribution to generation of energy. But the growing scarcity of resources demands ever greater effort for extracting fossil fuels and the employment of new, more efficient methods. In addition, harsh environmental conditions and other mechanical strains create the need for particularly dependable and robust technology. It is precisely these challenges that we address. Using precise, robust and low-maintenance sensors with explosion protection. These explosion-proof sensors are approved internationally and ideally suited for use in oil and gas extraction.

Application examples

  • Holding cable tension

    Reliable position feedback for tight wire cables

    The solution

    Floating drilling rigs are connected to the seabed using wire cables. To prevent damage, they must be held under tension at all times. This can be difficult during swelling. Because of this, the tension is hydraulically adjusted via the tensioning device. Our BTL magnetostrictive linear position sensors guarantee reliable feedback of the piston position of the cylinders.

    The features

    • Many interfaces
    • Space-saving with installation in the cylinder
    • Contact-free and therefore wear-free

  • Rising pipe – Monitoring tension

    Position measurement ensures intelligent leveling and tension maintenance

    The solution

    The task of wave compensation cylinders is to maintain the specified tension of the drill string and compensate wave movements. To do so, the hydraulic cylinders are attached between the drill string and the rig. Equipped with our BTL magnetostrictive linear position sensors, these intelligent hydraulics level movements and guarantee the necessary tension of the riser pipe. No matter how much the floating oil rig is currently rocking.

    The features

    • Length of up to 7.6 m
    • Explosion protected in the stainless steel housing

  • Positioning the drill string

    Certified protection against explosions

    The solution

    For fast and efficient drilling, pipehandlers take drill rods out of the magazine and position them directly over the borehole. Powerful hydraulics are needed in order to move the heavy rods. Our BTL magnetostrictive linear position sensors support the hydraulics and in doing so play a decisive role in promptly and correctly positioning the rods.

    The features

    • High temperature range
    • Robust and long-lasting

  • Controlling valves

    Certified protection against explosions

    The solution

    Control and shutoff valves also need to work reliably under rough environments. Especially if explosion protection plays an important role. Here, our certified BTL magnetostrictive linear position sensors guarantee the reliability and security that people and technology require.

    The features

    • High reliability
    • Many international approvals: ATEX, IECEx, among others

  • Erect and align hydraulic artificial lifts

    Precise alignment of artificial lifts over the borehole

    The solution

    Hydraulic artificial lifts need to be placed precisely over the borehole so that side loads and component wear are minimized as much as possible. Balluff's inclination sensors offer non-contact angle measurement for precise vertical alignment in multiple axes. The sensors operate by measuring the deviation from horizontal, up to 360° (one complete rotation).

    The features

    • Mounts directly on the equipment to be aligned
    • Space-saving and robust, well-suited to outdoor conditions
    • Fluid-based and MEMS technologies available to suit moderate to high accuracy requirements
    Position oil pumps with the help of inclination sensors

  • Controlling hydraulic artificial lifts

    Position feedback for hydraulic lift cylinders

    The solution

    Hydraulic artificial lift systems are enhancing energy efficiency and optimizing production rates through constant monitoring of downhole conditions and adjustment of the rate and duration of pumping operations. Controlling the velocity and stroke of a hydraulic lift is key to obtaining these benefits.

    Balluff magnetostrictive linear position sensors are available with operating strokes up to 7620mm to accommodate all but the longest-stroke lifts.

    The features

    • Non-contact, wear-free operation for long service life
    • Standard models for non-hazardous applications
    • Flameproof / Explosion-proof protection method for hazardous locations
    • NEC, CEC, ATEX, IEC, and many other international approvals for explosion-proof variants
