Abstract:
1. A method of servicing a wellbore, the method comprising: positioning a casing string comprising a first manipulatable fracturing tool (MFT), a second MFT, and a third MFT within a wellbore, wherein the casing string is positioned within the wellbore such that the first MFT is proximate to a first fracturing interval, such that the second MFT is proximate to a second fracturing interval, and such that the third MFT is proximate to a third fracturing interval, wherein the second fracturing interval is between the first fracturing interval and the third fracturing interval; manipulating the first MFT so as to provide a route of fluid communication from the wellbore to the first fracturing interval; communicating a fluid to the first fracturing interval via the route of fluid communication from the wellbore to the first fracturing interval so as to introduce a fracture into the first fracturing interval; obstructing the route of fluid communication from the wellbore to the first fracturing interval; manipulating the third MFT so as to provide a route of fluid communication from the wellbore to the third fracturing interval; communicating a fluid to the third fracturing interval via the route of fluid communication from the wellbore to the third fracturing interval so as to introduce a fracture into the third fracturing interval; and obstructing the route of fluid communication from the wellbore to the third fracturing interval, wherein introduction of the fracture into the first fracturing interval and introduction of the fracture into the third fracturing interval decreases the horizontal stress anisotropy within the second fracturing interval, reverses the orientation of the horizontal stress anisotropy within the second fracturing interval, or both.
