Abstract: The present disclosure relates to enzyme formulations and methods of using the enzyme formulations to reduce the viscosity of fluids used in hydrocarbon recovery. Some embodiments provide particles for well treatment, where the particles comprise an acidifier carrier and an enzyme co-encapsulated within a shell. The particles can, for example, allow a delayed or controlled release of the enzyme in a high temperature, high pressure environment.
