\nPEEK Centralizer\n<\/h1>
\nThe Casing Centraliser is also an important mechanical component of oil and gas wells. Its purpose is to be able to keep tubing or casing centered in the wellbore, so that it does not press against the wall of the well.
PEEK centraliser is not just designed to absorb 210 \u2103 temperatures down the hole, so that the tubing string slides as silk to the designated depth. More importantly, it ensures that in the process of deployment of 3000-metre length using a PEEK centraliser, the hook load is minimised by around 15 - 20 tonnes as compared to a steel centraliser. This saving does not just result in time savings but also reduces the potential of drilling to be stopped or even the loss of the well.\n<\/div>\n<\/div><\/div><\/div>\n<\/section>

    \n Friction resistance: \n <\/div>\n\n <\/li>\n\n <\/ul>\n\n<\/div>
    \nIn the run-in process 2000-metre long horizontal section: Friction coefficient in the centralisers of traditional steel: up to 0.5.
    At 1500 metres, hook load loss is nearly 45 tonnes and at any given time, there is the risk of self-locking. \n<\/div>
    \nPEEK centraliser: The lowest possible coefficient of friction is 0.12. Hook load loss is held at less than 12 tonnes under the same conditions. This 33 tonne hook load saving equates to an adequate amount of what could be called safety margin so that should your tubing string be unexpectedly affected by a borehole collapse or rock fall, you can reach it. It is not only about deploying quicker, but is a life-saving backup in times when it counts!

      \n Temperature Resistance:\n <\/div>\n\n <\/li>\n\n <\/ul>\n\n<\/div>
      \nThe temperature has been raised to 260 \u00b0C.
      At ultra-deep wells, the strength of materials falls exponentially with each 10 \u00b0C rise in bottomhole temperature. High-temperature nylon, commercially available: softens above 140 o C, not just becoming structurally unsupportive, but may also stick to the wellbore walls and result in stuck pipe.\n<\/div>
      \nOur compression centralisers: PEEK PEEK: PEEK has compressive strength over 100Mpa even at intensely high temperatures of 260\u00b0C.
      Field experience: At Tarim Oilfield, a 8,200-metre ultra-deep well, in which core temperatures were 198 \u00b0C, we used 120 PEEK centralisers.
      It took 72 hours to get to the bottom of the descent. When retrieved, the rib deformations had less than 0.2mm.

        \nIn high-sulphur wells in the Middle East our products have shown ten years of service life. \"Numerous clients have complained that steel centralisers corroded into rust debris within two years of deployment,\" In highly acidic environments with H2S concentrations of more than 15%:
        Traditional metal centralisers:
        Extremely high risk of hydrogen embrittlement with an average life expectancy of less than 1.5 years. Should they break and drop to the bottom of the well the cost of recovery is in the hundreds of thousands of US dollars.\n<\/div>
        \nPEEK Centralizer
        We performed 720 hour simulated saturated strong acid immersion testing. <0.5% loss of mechanical strength was recorded. Our 360-degree precision moulding process not only provides protection against chemical corrosion, but also 150MPa ultra-high pressure testing (equivalent to 15,000 metre deep sea pressure). In Middle Eastern environments characterised by high salinity, extremes of heat and high acids, we ensure stable operation for over 10 years - genuinely meeting 'one unit per well, no replacement required throughout its life'.

        • The \"Golden Clearance\" (ID vs. Pipe OD):<\/strong>
          Our PEEK centralizer ID will be 1.0mm-2.5mm more OD than the largest pipe OD.
          Why? This precision margin is critical so that the centralizer can be easily rotated or slid when installing the wells without causing the wobbling effect that causes fatigue due to vibration in the ultra-deep wells.<\/li>\n
        • Rib Blade Angle (Spiral Design):<\/strong>
          All PEEK centralizers have a 20\u00b0 to 30\u00b0 spiral vane. This is not to be made pretty--it gives the cement slurry a \"Vortex Effect\" so that it is assured that results in 95%+displacement efficiency, and does away with mud pockets behind the pipe.<\/li>\n
        • 100% Customization Capability:<\/strong>
          Since we are CNC 5 axis machining rather than crude injection machining, we can readjust the Rib OD in 0.1mm steps to suit your particular borehole requirements. In the event that your borehole is tight (say by swelling shale), we can shave the ribs to offer the optimum Standoff and Running Force.<\/li>\n<\/ul>\n<\/div>\n<\/div><\/div><\/div>\n<\/section>
