Abstract
Fracturing (or fracking fluids) used to enhance hydrocarbon extraction for subterranean rock formations may impede the recovery of the targeted hydrocarbons. Thus, it is common practice to inject a breaker into the subterranean rock formation to reduce the viscosity of the fracking fluids. The chemicals used to reduce the viscosity, called breakers, need to act after the tracking fluids have opened the pores in the subterranean rock formations, but before hydrocarbon extraction is hindered. A novel method for controlling the release of the breakers is disclosed. This method comprises encapsulating the breakers within a capsule comprised of water-soluble polymers and water-insoluble polymers. The water-soluble polymers are dissolved controllably by fluids within the well, allowing the breakers to react with the fracking fluids.
