Successful OH Multistage Fracturing Operations with Saltel FracPackers

Context

  • Gas producer horizontal well with openhole multi-stage completion (balldrop sleeves) 41/2in 13.5 lb. /ft. P110 run in 61/8in openhole.
  • The client selected a combination of 2 different Isolation Packers: 15 Hydromechanical Isolation packers (competition) with 5 Saltel Expandable Steel FracPackers located at the toe.

Solution

Saltel FracPacker is a patented metal expandable packer specially designed for OH multistage frac operations. Saltel Industries provided five 10k 41/2in ISO 14310 V3 qualified to 10,000psi (68.9Mpa) differential pressure. The FracPackers came set on 10ft Pup Joint (41/2in 13.5ppf P110), with pin-box LT&C connections. The short length of the packer (3.3ft) combined with its reduced intial diameter (51/2in) facilitated the Running In Hole. The FracPackers were first run to depth from 2,675ft (3,850m) to 13,800ft (4,200m) in the horizontal section, then successfully expanded a couple of months later with the frac fleet.
