A LUBRICANT built around a positively charged molecular structure by developer ProOne is said to boast 50 times the film strength of conventional lubricants.
The Xtreme Pressure Lubrication (XPL+) technology, distributed in Australia through DistributionNOW, is used in over 700 wells throughout North America and is said to result in a system-wide friction reduction of more than 70 per cent.
Among the key attributes of the lubricant are improvement of the rate of penetration (ROP), delivering a 20% to 50% reduction in torque and drag, helping free stuck pipe and helping eliminate excessive and expensive trips.
Yet, operators have also found that benefits extend to other aspects of downhole drilling, observing that the lubricant solves drilling challenges including long horizontals, deviated wells, multiple doglegs, and the especially costly problem with short drill bit life.
Similarly, since this is specifically a mud additive, its lubricity extends lifecycle of mud pumps and mud motors.
It allows operators to drill curves in half the time, set casing and slide lining quicker, greatly reduce hook load and maintain or even increase weight on bit (WOB).
The XPL+ range has also seen two spin-offs: Nitro and CoilPro, both of which have the key features of the original breakthrough, including attraction to intense heat and pressure along with exceptional film strength.
Nitro used at only 1.5% reduces metal-to-metal coefficient of friction more than other lubricants used even at 6% or 7.5%.
CoilPro is becoming known for the ability to mill more plugs than ever which, as operators know, is particularly important since rarely can all the well’s plugs be milled.
A pipe-on-pipe treatment, it combines better drilling efficiency with reduced costs, regardless of the type of wellbore with coil tubing fluids. The wellbore may be horizontal, vertical or deviated.
All these lubricant technologies – the original XPL+, plus the new Nitro and CoilPro formulations – are highly environmentally-friendly, as well as being non-toxic to marine life in offshore drilling.
