Claim:
1. A method of using a zonal isolation and treatment tool for introducing a treatment fluid to a targeted stratum within a formation such that the targeted stratum is converted to a treated stratum, the method comprising the steps of: introducing the tool into a well bore such that the targeted stratum is positioned between an upper isolation packer and a lower isolation packer of the tool, where the well bore is defined by a well bore wall, where the well bore traverses the formation from a surface downwards to at least the targeted stratum, where the well bore is filled with a well bore fluid, and where both the upper and lower isolation packers are each operable to fluidly seal against the well bore wall upon inflation; operating the tool such that a reversible fluid booster pump of the tool draws the well bore fluid into the tool and each of the upper and lower isolation packers are inflated with the well bore fluid such that both the upper and lower isolation packer seal fluidly against the well bore wall, where the upper isolation packer seals uphole of the targeted stratum and the lower isolation packer seals downhole of the targeted stratum such that an isolated well bore volume forms between the upper isolation packer and the lower isolation packer, where the isolated well bore volume is selectively fluidly accessible to a remainder of the well bore through a treatment fluid distributor of the tool, where at least a portion of the well bore wall associated with the targeted stratum is located between the upper and lower isolation packers, where the portion of the well bore wall associated with the targeted stratum is operable to provide fluid communication between the isolated well bore volume and the targeted stratum, where the tool includes the reversible fluid booster pump that is operable to draw the well bore fluid into the tool through a pump fluid access port, and where the tool includes the treatment fluid distributor that is operable to provide selective fluid access between the isolated well bore volume and the remainder of the well bore; introducing the treatment fluid from the surface into the well bore such that the treatment fluid is positioned within an annular space defined between the well bore wall and the tool proximate to the pump fluid access port of the tool; operating the tool such that the reversible fluid booster pump draws the treatment fluid into the tool from the well bore through the pump fluid access port and that the treatment fluid distributor discharges the treatment fluid from the tool out through a treatment fluid port and into the isolated well bore volume; and maintaining the isolated well bore volume such that the treatment fluid interacts with the targeted stratum through the portion of the well bore wall associated with the targeted stratum, where the treatment fluid forms a spent treatment fluid and the targeted stratum forms the treated stratum upon interaction with one other.
