Abstract:
A layer of permeable material is positioned on an area of lost circulation lithology in a wellbore. An example of the permeable material includes a planar member with perforations that is rolled into and retained in an annular configuration. The permeable material is lowered into the wellbore adjacent the area of lost circulation and allowed to unroll and expand radially outward against walls of the wellbore. The wellbore wall along the area of lost circulation lithology can be reamed out so the layer of permeable material is out of the way of a drill bit. Applying a bridging agent on the interface where the permeable material contacts the wellbore wall forms a flow barrier.

Claim (Index 1):
A method of operations in a wellbore having a lost circulation zone comprising:\n providing a layer of material that is retained in an annular configuration and that has perforations; disposing the layer of material in the wellbore and adjacent the lost circulation zone; expanding the layer of material radially outward and into contact with the lost circulation zone to define a tubular member having an inner radius and an outer radius; and injecting fluid within the inner radius that has particles of a bridging agent entrained within and that accumulate in the perforations to block flow through the perforations and form a flow barrier across the layer of material.
