Anchored Production Straddle.
The Anchored Production Straddle (APS) is designed with high expansion in mind, at the same time providing a significant through-bore. The APS can be configured to solve a range of production control challenges.
The use of solid elastomeric elements maintains integrity in terms of variation in temperature and pressure. These unique one-piece elements have integral support and also features positive retraction when un-set. The slips are bi-directional allowing loads in either direction. Designed to set in slick casing or tubing the APS is uniquely capable of being run and set reliably in cross-flow conditions, which are often the cause of mis-runs and ultimate failure of inflatable devices.
The APS is basically configured as two packer modules - one at the bottom and one at the top of the assembly - with standard spacer pipe in between. Dependent on the type of application, the APS can also be delivered with an additional slips section, built-in PBR functionality etc.
Most industry standard setting tools can be used to set the APS. Provided the overall weight allows, the whole assembly can be deployed in one run either on slickline, e-line or coiled tubing. Retrieving the APS is generally a one-trip operation on slickline using a standard GS pulling tool (top module) in combination with a shifting tool (bottom module).
Features
