In the Oil & Gas market, the easy accessible reservoirs are depleting. The industry is moving toward new frontiers such as deepwater and non-conventional oil and is developing new methods like enhanced oil recovery. This is a strong incentive to use new technologies that enable an efficient exploration and production of these difficult reservoirs.

We have developed a new concept for spoolable composite tubulars that adresses this need. Our unique continuous thermoplastic composite tubing is lightweight, spoolable, fatigue resistant, corrosion free, strong and collapse resistant. This pipe system can be used for a variety of applications, such as flow lines, coiled tubing, service intervention lines and deepsea risers. It is produced with a fully automated, continuous production process that is cost-efficient and easy scalable.

The basic idea of our product is to use a 'one-material concept', in which the internal liner, fibre reinforced structural layers and the outer coating are all of the same thermoplastic polymer. These layers are melt-fused together to provide an inherently strong interface between the layers. The resulting product is very simple compared to other flexible pipe systems available on the market, and therefore robust and reliable. There is one structural layer that can handle all the different loads, which makes the pipe very efficient and makes it possible to mount the connectors and end-fittings directly to the pipe.

Your requirement for a composite tubular may be driven from different angles. The most important drivers and our proposition are outlined below:

• Spoolability: The thermoplastic composite tubulars allow higher spoolability than thermoset tubulars.
• Fatigue: In applications where tubulars are run in and out of wells or run as service intervention line offshore, the fact that thermoplastic tubulars do not show any fatigue is a great benefit.
• Collapse strength: As we apply the 'one material concept' optimal bonding is achieved between the layers and the collapse strength is unsurpassed. It makes thermoplastic composite tubulars interesting for offshore applications as a low-cost alternative to hybrid solutions seen in umbilicals and flexible pipes.
• Abrasion: In dredging, thermoplastic polypropyleen liners are used extensively as their wear resistance outperformes steel in working with rocks, stones and sand.
• Corrosion resistance: Composite tubulars are completely corrosion resistant and have high chemical resistance in general. This offers viable solutions for instance in H2S /CO2 or brine environments. Also for well intervention using acids, our Thermoplastic Composite Pipe is an attractive alternative to steel coil.
• Electrical / Magnetic Conductivity: The electrical and magnetic properties of the tubular can be tailored. This is important for logging applications or tubulars that need to include power conductors such as in our Composite Coiled Tubing application.
• Cost: We can assess the application quickly and advise on cost benefits either on the tubular cost directly, on installed cost or on total cost of ownership.
