Proxima HPR resins help customers drive faster completions, more reliable services, and lower scrap rates. Proxima HPR resin technology delivers with the right combination of thermal stability, strength, toughness, reliable machining, and fast drill-out.

Tough Proxima HPR Casting Resins

When operators use inner string casing equipment, which require drill out after use, materials that are strong enough for challenging downhole environments are often slow to drill or can adhere to PDC bits. Bit replacements are costly and time consuming, which poses an unnecessary risk to operating margins in today’s price volatile market.

Proxima HPR casting resins uniquely offer excellent thermal stability and toughness combined with fast and easy PDC drillability and machining. Proxima HPR thermosets offer better drillability than aluminum, better thermal stability than standard thermoplastics, and better wear resistance than typical compression molded thermosets. The result is downhole equipment driving faster completions, shorter rig-times, and overall cost savings.

Features and Benefits. Tough Proxima HPR thermosets are uniquely formulated to solve a wide variety of downhole challenges.

Performance Continuous Fiber Composites

Proxima ACR composites offer better thermal stability and reliability than standard composite systems and offer the corrosion and chemical resistance of a hydrocarbon polymer. These thermoset composites can provide mechanical protection to valuable downhole probes. The hot-wet properties and chemical resistance outperform competitive resins such as unsaturated polyesters, vinyl esters, and epoxies. Additionally, Proxima ACR composites are reliably made with low scrap rates and high-quality part production, which are often challenging with competitive resins due to brittleness and cracking.

Features and Benefits. Tough Proxima ACR thermoset composites are formulated to solve many downhole challenges.

Corrosion and chemical resistance
Excellent thermal stability
Machinability
Resistance to crack propagation
Outstanding fatigue properties

Properties and Highlights

Proxima ACR glass and carbon fiber composites offer strength and compressive properties suitable for challenging downhole conditions.
