Patent abstract
A liner rotates a bit to make more hole. The liner has openings with inserts in them to lend torque resistance to the liner. The inserts have a passage with a send control media in the passage and a seal so that the liner can hold pressure for run in to get proper circulation through the bit. When sufficient hole is made, the liner is hung off an existing cemented tubular and the seal for the passages with the sand control media is removed by a variety of techniques so that the formation can be produced in a single trip.
