CobaltAlloy™ Oilfield tubing features a protective layer with "mechano-tribological" properties ... engineered for abrasion resistance, corrosion protection and chemical protection, yet still maintains excellent impact resistance. A unique protective internal layer of ceramic and metal alloys to protect the production tubing from damage during artificial lift operations.
YES, a full range of CobaltAlloy™ tubing pup joints are available with the CobaltAlloy™ surface treatment process. Preventing coupling corrosion to ensure longer lifecycle of your critical production tubing.
YES, CobaltAlloy™ Tubing Couplings also have an internal protective layer to prevent corrosion between the threaded connections and is also compatible with Cobalt® Sucker Rod Guides to offer a unique rod pumped well completion package.
CobaltAlloy™ features reduced friction, lower wear, reduced corrosion, open flow, reduced torque and drag, increased production and reduced well workovers.
CobaltAlloy™ Production tubing is available in any API tubing grade or size. Other heat treated or plated tubing alternatives are limited to J55 only.
CobaltAlloy™ tubing is 30x smoother than new "untreated" tubing. The very low co-efficient of friction ensures minimum production fluid drag and reduced downhole torque and rotational friction.
CobaltAlloy™ Production tubing is also ideal for ESP and ESPCP well completions.
The unique CobaltAlloy™ protective surface has been engineered to be compatible with Cobalt Premium Sucker Rod Guides.
CobaltAlloy™ tubing and ARPMAX Polymer Rod Guides will optimize rod pumped well completions. Cobalt Sucker ROd Guides have a unique (patent pending) "Self-Lubricating" lubricant for a very low co-efficient of friction and longer rod guide wear resistance.
CobaltAlloy™ tubing can be installed using the same equipment as standard production tubing.
Refer to CobaltAlloy™ Tubing Installation Procedures.
The CobaltAlloy™ asset cost is significantly lower than hardened tubing alternatives. Typically, CobaltAlloy™ Production Tubing lasts 3x longer than standard "untreated" steel tubing, depending on well operating conditions and well completion design.
The CobaltAlloy™ Thermo-Mechanical protective layer is 0.017" (0.450mm) thick. That equates to more than double the protection of your production tubing when compared to high cost thermo-chemical tubing treatments which are only 0.008" thick.
CobaltAlloy™ production tubing is effective in a variety of producing environments including H2S, CO2 flood, water flood, and steam injection, and can be used in wells with operating temperatures as high as 300F (150C)
Heat Treated or Plated tubing have been proven to suffer from "Micro-Cracking". This is a result of thermal fatigue and bending. Heat treated tubing requires each joint to be re-straightened after the tubing cools following removal from the furnace. Therefore the internal surface has micro-cracks, as well as thermal fatigue (weakening) of the tubing metallurgy. Micro-cracking leads to premature failure due to corrosion.
The CobaltAlloy™ Internal protective layer does not effect the original tubing metallurgy characteristics, will not split or micro-crack, will prevent corrosion, scale buildup and abrasive wear, even when installed in deviated well completions. CobaltAlloy™ is ideal for installation in PCP wells where sucker rod oscillation is very common.
