Weatherford has released a retrievable, hydraulically set production packer that provides single trip speed and efficiency. The Hellcat 2 Intelligent Completion Packer has a short, compact design making it ideal for highly deviated wells and doglegs. Its eight control-line feedthroughs facilitate complex well designs, and the large primary fullbore concentric mandrel provides clear and easy access for wireline tools and standard accessories. Its hydrogenated nitrile sealing element, with metal-to-metal extrusion barrier, resists oil and chemical exposure, and the slips located below the packing element reduce accumulation of debris that can create difficulties during retrieval.

The packer can be used in intelligent packer completions, subsea completions, for deviated and horizontal well completions and for zonal isolations.

According to the company, some of the other design features include:

• Pressure-testable connections on each control which reduces the risks associated with intelligent well completions.

• Low setting pressure of 3,500 psi reduces tubing stretch during setting. In many cases, setting can be accomplished with rig pumps, reducing expenses for high-pressure pumps.

• No mandrel movement during setting allows stacked applications.

• Shift-to-release capability using a wireline shifting tool provides operational simplicity and reduces the risk of premature failures under varying load conditions.

• Cut-to-release capability (available by special order) reduces the risk of premature failure of shear-out type packers under extreme loading.

• Ability to set packer after flanging provides greater operational flexibility and safety.

The Hellcat 2 packer has undergone rigorous testing to ISO 14310 standards in Q-125 casing and has been successfully used in the field according to Weatherford. In Phase 1 of a seven-well project for a major operator in West Africa, 4 Hellcat 2 packers were installed in one well as an ongoing project, with an average of three packers per well expected in the subsequent six wells.
