Victrex Composite helps fight extreme oil & gas conditions

Given the proven track record of VICTREX PEEK-based solutions, the long-standing AFP technology available from Automated Dynamics enables composites to be built layer by layer in an automated process. This has numerous advantages over curing by autoclave and - with the addition of a laser heating capability - enables up to a ten times improvement in throughput in certain applications.  

According to Brett Kimball of Automated Dynamics, "Demanding downhole applications often require continuous fiber composites made from VICTREX PEEK predominantly because of their higher modulus and strength when compared to short fiber composites.
 
These applications include antenna shields for various measurement techniques used with LWD tools, electrical and structural isolators (gap subs) on M/LWD (measurement/logging while drilling) tools, and housings and logging sleeves for wireline resistivity tools." 
 
Another major advantage of VICTREX PEEK-based composites is their hydrolytic stability with moisture absorption limited to about 0.2%. Thermosets, in contrast, typically absorb 2% moisture, precipitating dimensional instability and cracking. Thermoplastic composites will also support metal-to-composite interfacing. Automated Dynamics has also successfully used PEEK-based APTIV films as a joining technology for numerous applications.
 
The outstanding properties and manufacturability of VICTREX PEEK-based composites enable their implementation in numerous downhole and subsea applications. Further development of PEEK-based materials is expected to keep pace with the increasingly severe demands of oil & gas environments.
 
The industry can remain confident that testing of VICTREX PEEK-based composites in extreme environments will continue to deliver excellent performance results making it the material solution of choice whenever an alternative to metals and thermosets is required for critical oil & gas applications.
