Abstract
Method is provided for preventing fluid from entering a well, such as a producing well, during a hydraulic fracturing treatment in another well completed in the same reservoir. Degradable ball sealers or degradable particulate material is injected into the well and pressure is maintained in the well during the fracturing treatment to prevent influx of fluid.
Claims10
A method for preventing influx of fluid into a first well having casing during or immediately after the time of a hydraulic fracturing treatment of a second non-intersecting well completed in the same reservoir, comprising:
- providing a quantity of ball sealers and degradable particles;
- injecting the quantity of ball sealers or degradable particles together into the first well in a carrier fluid to plug or partially plug perforations or ports in the casing of the first well;
- and
- hydraulically fracturing the second well while maintaining pressure in the first well so as to maintain plugging or partial plugging of the perforations or port in the first well, thereby preventing influx of fluid from the second well into the first well as a result of hydraulically fracturing the second well.
