Abstract:
A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The WST is positioned along with the RSM at a desired wellbore location. After the WST sets and seals the RSM, a conforming seating surface (CSS) is formed in the RSM. The CSS is shaped to engage/receive RPE deployed into the wellbore casing. The engaged/seated RPE isolates heel ward and toe ward fluid communication of the RSM to create a fracture zone. The RPE's are removed or left behind prior to initiating well production without the need for a milling procedure. A large ID RSM diminishes flow constriction during oil production.

Claim (Index 10):
The wellbore plug isolation apparatus of  claim 1 , wherein the restriction sleeve comprises an end configured to mechanically couple with another restriction sleeve.
