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.
Left: Swelling rate of swellable rubber in 7.5% KCl at 180°F. Right: swelling rubber in fresh water and 7.5% KCl at 250°F
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
