The primary drivers for the adoption of composites in this sector include corrosion resistance in offshore platforms and chemically aggressive environments; weight savings in subsea and surface systems, which facilitates handling and reduce structural loads; electrical insulation properties, which eliminate the need for grounding in explosive or hazardous areas; and extended lifecycle resulting in reduced downtime, maintenance frequency and total cost of ownership.
Composite integration in upstream infrastructure
Upstream, composites are mainly used in piping systems, particularly for subsea flowlines, risers and jumpers. While global players are increasingly deploying Thermoplastic Composite Pipes (TCP) for these applications, India predominantly uses glass-reinforced thermosetting pipes, mainly to reduce costs and utilise established supply chains. These composite pipes generally feature glass fibre reinforced polyester linings, providing superior resistance to abrasion and corrosion, especially in saline or acidic environments.
Composites are now being used for drilling components too, in tools such as frac plugs, bridge plugs and frac balls. These components benefit from high strength-to-weight ratios and resistance to degradation in high-pressure, high temperature environments. Companies like Lamtuf Plastics Ltd. in Hyderabad supply high-performance glass-epoxy laminates (e.g., FR4, G10) to manufacturers like Atlas Fibre, supporting applications in downhole tooling and wireline support equipment.
