WAB® for Well Completion
Application flexible, high performance packer
Through its versatility in application, and robustness in design, the WAB (Welltec Annular Barrier) for well completions can be utilized to provide solutions to many requirements throughout the completion phase of a well. The WAB's IS014310 V0 leak rate capability, when set in cased hole, enables the incorporation of the WAB as a high pressure production packer for both HP gas, and oil well applications.
Furthermore, the ability to rotate and reciprocate during installation and cementing operations, and then expand and seal, on demand, via a onetime application of surface, in horizontal applications, allows the WAB to be incorporated as a Liner Hanger, significantly reducing risk and complexity, in these often-challenging applications. Couple this with the V0 leak rate capability, the WAB liner hanger offers significant benefits over conventional, dual-stage set, liner hangers.
Our ISO 14310 rated, metal expandable WAB for open hole zonal isolation, facilitates the ability to deploy ‘cementless’ extended reach, multi zone, horizontal, lower completions.
The WAB provides the on- demand, high pressure zonal isolation across varying borehole geometries unaffected by thermal changes in the wellbore, so often a problem in conventional open hole isolation.
