In western Canada, many cold production wells must be prematurely abandoned due to watering-out. High permeability channels (wormholes) are known to develop during cold production. Tracer tests and wormhole growth experiments and simulations suggest that open (sand-free) channels form within the wormholes once they reach a certain length. Wormholes often break into water zones leading to premature abandonment of many wells. Different sandy polyacrylamide gel systems, developed for blocking these open channels, have been used as treatments, and whose results are reviewed here. These systems combine good injectivity with higher strength, as tested in the lab. In addition, a series of viscosity, settling rate, and gel strength tests were performed for different sand concentrations, shear rates, polymer concentrations, molecular weight, and salinity. A promising sandy polymer gel system for water shut-off applications in cold production is described.
