A Major Mid-Continent Operator needed a solution that could cover four perforations that were prematurely shot in the heel of the horizontal Woodford Shale well.  The ESeal HP Liner was successfully tested to 13,500 psi and passed 31 fracturing stages to re-establish the fracturing program.

An operator in the Anadarko Basin was running their 5-1/2 in. production string in a horizontal, unconventional shale well when they were unable to get cement to the top of the curve.  They decided to perforate above the curve and squeeze cement down the annulus of the 5-½” production string.  ...

SET technology is the result of a cold-working process that permanently deforms the pipe without any additional heat. The procedure inherent to expanding tubulars takes the steel beyond its elastic limit into the plastic region of the stress-strain curve, while remaining safely below ultimate...
