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 18):
A wellbore plug isolation apparatus comprising:\n (a) a restriction sleeve having a body, the body in an unexpanded condition configured to fit within a wellbore casing, the expandable body of the restriction sleeve having a sleeve thickness, the sleeve thickness tapering in a wedge to a first terminal edge of the body, the body comprises an end configured to mechanically couple with another restriction sleeve, at least one gripper on an outer surface of the body, the gripper configured to grip an inner surface of a wellbore casing, the body configured to be hooped outward with a wellbore setting tool to an expanded condition swaged against an inner surface of the wellbore casing; and (b) a restriction plug configured to seat against the expanded restriction sleeve.
