Figure F9. Generic schematic (not drawn to scale) of CORK observatory with four concentric casing strings, one set of packers at depth, and an "L-CORK" design with a lateral casing section extending from the inner 4½ inch CORK casing and coming up the free-flow ball valve at the wellhead. This schematic shows a CORK very similar to the one that will be deployed in Hole SR-2B. The CORKs in Holes SR-2A and 1027C will have two sets of packers, and the CORK in Hole 1027C will have three rather than four concentric casing strings because the conductor casing will be 16 inches in diameter.
