  • Acid fracturing treatments in hydrocarbon-bearing formations in close proximity to wet zones
    Patent number: 11408261
    Abstract: System, methods, and devices for simultaneously fracturing a target formation and an adjacent secondary formation are disclosed. The simultaneous fracturing operations interfere with each other to form in-situ dynamic barriers. The in-situ barriers prevent acid from the fracturing treatment in the target formation from invading the secondary formation and, in some instances, sealing formation rock at the location of the in-situ barrier to prevent or reduce water movement from the secondary formation into the primary formation.
