Method and apparatus for zonal isolation and selective treatments of subterranean formations
Abstract:
A zonal isolation and treatment tool having a reversible fluid booster pump with a reversible motor, both an upper isolation and a lower isolation packer having an elastic surface, a treatment fluid distributor that provides selective fluid access and an electronics control package that couples to the reversible motor. The method includes introducing the tool into the well bore, inflating the upper and lower isolation packers using well bore fluid, introducing the treatment fluid into the well bore such that it is positioned proximate to the tool, operating the tool such that the treatment fluid is introduced into the isolated well bore volume, and maintaining the isolated well bore volume such that the targeted stratum forms a treated stratum.
