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 10):
A method of wellbore operations comprising:\n providing a wellbore liner having a tubular shape with an inner radius and an outer radius and perforations extending through a sidewall of the liner; disposing the liner in the wellbore and adjacent a location where fluid flow communicates between the wellbore and a formation adjacent the wellbore; providing a fluid with entrained particles of a bridging agent, the particles having diameters less than diameters of the perforations; and\n creating a flow barrier across the liner by flowing the fluid through the perforations and along an inner surface of the wellbore liner so that the entrained particles become deposited in the perforations and accumulate in the perforations to block fluid flowing through the perforations from within the liner.
