ESET High Performance System Enables Maximum Size Completion
A major operator in the Norwegian North Sea anticipated problems while drilling a 12-¼ x 13-½ in. hole section which required setting 10-¾ in. casing early. This left a section of overburden exposed above the reservoir.
The 8-5/8 in. ESET HP System isolated the overburden section, providing an 8-1/2 in. drift ID. This enabled the reservoir to be drilled and completed with a 7-5/8 in. liner, maximizing production capability.
