ESET® Expandable Liner Enables Planned Drilling Operations; Saves 25 Days of NPT
An Operator drilling multiple wells in South Texas encountered a loss zone 500 ft. below the shoe of the intermediate casing in their well. The Operator had also encountered this loss zone on two offset wells and was prepared with options to address the loss zone. Normally 9-5/8 in. casing is run as an intermediate casing string, but when this loss zone is encountered and 7-5/8 in. casing set, completing the well with 5-1/2 in. production casing becomes a challenge.
