Abstract:
A method of isolating an open-hole section of a wellbore includes positioning, a liner, a valve, and a liner hanger that are attached to a working string adjacent an interface between the open-hole section and a cased section of the wellbore. The method includes injecting cement through the liner and the valve to form a first balanced cement plug within the open-hole section of the wellbore. Generally, the liner, the valve, and the liner hanger are secured within the balanced cement plug. After the balanced cement plug is set, the liner hanger is actuated and the liner, the valve, and the liner hanger are detached from the working string, which causes the valve to close and creates a mechanical barrier between the balanced cement plug and the working string. Additionally, the mechanical barrier is covered in cement to form another balanced cement plug.

Claim (Index 7):
The method of  claim 4 , wherein injecting a second hardenable fluid into the working string so that the second hardenable fluid flows into the wellbore to cover the liner, the valve, and the liner stabilizer with the second hardenable fluid creates a second cement plug that is a second hydraulic seal.
