High Strength Water Swellable Rubber

CNPC USA developed proprietary swellable rubber with high strength. A short length, small OD, multi-segment swellable packer was designed and manufactured. Our swellable packer has higher pressure rating per length than the commercial swellable packers in the market that can greatly reduce the run-in risk and provide stable isolations in downhole. The swellable rubber could have many applications in Oil and gas applications.

Applications

  • Open hole and cased hole swellable packers
  • Long-term isolation
  • Effective reservoir compartmentalization
  • Inflow control device completions
  • Straddle assemblies
  • Gravel-pack assemblies
  • Multistage matrix acidizing
  • Loss circulation control

Features and Benefits

  • High tensile strength
  • High sealing force (Hardness of the swellbale rubber is 50% higher than that in the market
  • Temperature rating up to 300°F
  • Engineered delay mechanism can be applied
  • Wide adaptability of swell fluid from 0-10% salinity
