(42) NEW HIGH PERFORMANCE RESIN FOR THERMOPLASTIC LINERS

Corrosion enhanced abrasive wear is a common cause of failure in sucker rod systems. The combination of high side loads caused by deviation and the presence of corrosive chemicals creates a very difficult environment for operators. The cyclical loading nature of sucker rod system adds to the problem, leading to premature failures in rods and tubing. Operators are turning to many technologies to increase mean time between failures (MTBF) in these challenging wells. Thermoplastic liners is one of the many options to extend run life in deviated wellbores. Liners are extruded from specialty compounded resins, each with its own set of advantages and disadvantages. A new resin is now 
being extruded to fill the void between 200 and 250 degrees Fahrenheit, allowing operators to maximize the benefit of lined tubing at a more economical price than higher temperature resins. This paper summarizes the properties of the new resin in comparison to the other resins currently on the market.
