METHODS AND APPARATUS FOR DRILLING, COMPLETING AND CONFIGURING U-TUBE BOREHOLES

摘要

A well system includes a borehole comprised of a first and second end surface locations and a subterranean path therebetween. A first casing string extends along a portion of the subterranean path from the first end surface location, providing a first cased portion. A second casing string extends along a portion of the subterranean path from the second end surface location, providing a second cased portion. An uncased portion of the borehole is provided between the first cased portion and the second cased portion. A first liner section having a first distal connection end extends within at least a portion of the first casing string. A second liner section having a second distal connection end extends within at least a portion of the second casing string. Finally, a bridge pipe bridges a gap between the first and second distal connection ends and defines a fluid passage therethrough.
