摘要： A method for addressing the problem known as formation breathing occurring during the drilling of a subsea well in an earth formation in performing a series of leak off tests to determine the earth formation fracture propagation pressure and the earth formation fracture reopen pressure and maintaining the hydrostatic pressure on the earth formation in a range between the fracture reopen pressure and the fracture propagation pressure.

摘要： Friction reducers for hydraulic fracturing fluids, hydraulic fracturing fluids containing the friction reducers, and methods of making and using same are disclosed. The friction reducers comprise ethylene oxide polymers, propylene oxide polymers, ethylene oxide-propylene oxide co-polymers, and combinations thereof, and can further comprise a dispersant, such as polypropylene glycol. The friction reducer formulations can be active across a wide range of brine salinities, and tolerant of high levels of divalent cations in solution. The friction reducers can have a cloud point temperature, above which temperature they can precipitate out of solution and deposit on a surface of a hydrocarbon-bearing formation to inhibit hydration of the shale formations lining the fractures.
