Low Molecular Weight Polyacrylamide
Crosslinkable to form a rigid gels for water shut off
The sample you selected was successfully added to your cart.
Rigid gels for near wellbore penetration to shut off water influx
High permeability layers with crossflow
Temperature stability dependent on specific formulations (testing required).
Dissolves readily in fresh waters or brines to for strong and temperature tolerant gel
Exhibits very low order of oral toxicity
Salt insensitive, and can be used in pH range of 3.3 – 12.5
Rate of gelation is controllable through crosslinker concentration and temperature
Sodium lactate may be used to retard gelation process in higher temperatures
Sodium thiosulfate may be used to accelerate gelation process at low temperatures
Ionic Bond Crosslinking Mechanism with suitable metallic or organic crosslinking agents, such as chromium acetate, or high molecular weight polyethyleneimine
Testing must be carried out in order to confirm application and advise the crosslinker and concentrations.
It should also be tested to ensure compatibility with other fluids systems encountered. Incompatible with: strong acids, strong bases, strong oxidizing agents
