|Arrowset I-X Mechanical Set Packer
ASI-X Packer is the most versatile of the mechanically set retrievable packers and may be used in any production application. The ASI-X Packer is suited for treating, testing, or injection applications, in pumping or flowing wells, either deep or shallow. The packer can be left in tension or compression, depending on well conditions and the required application.
A large internal by-pass reduces swabbing when running and retrieving. The by-pass closes when the packer is set and opens prior to releasing the upper slips when retrieving to allow pressure equalization. The J-Slot design allows easy setting and releasing; 1/4 turn right-hand set, right-hand release.
The ASI-X Packer is also available in an HP version which can withstand differential pressures up to 10,000 PSI.
This feature allows the packer to be utilized in completions where high pressure treating operations are performed and it is desirable to leave the tool in the well for production.
Features and Benefits
Where conditions permit, the lowest cost completion with a tubing string leaves the tubing hanging from the wellhead with no packer used to isolate the casing annulus. This system allows production to flow up the tubing, the annulus, or both. The tubing string provides a means for the injection of inhibitors or the circulation of kill fluids. It typically includes a tubing retrievable safety valve with cement-through capability. In addition to the tubing, a seating nipple or a profile landing nipple can be providing for a standing valve or retrievable plug. The wireline entry guide will ensure reliable retrieval of wireline tools that might run past the tubing end.
Although this completion is economical, its use is limited by fl owing conditions and concern for protection of the tubular goods. Efficiency of fl ow can be compromised, and any leaks in the tubing or casing are difficult to detect. It also adds to the difficulty in gathering bottom hole pressure survey data.
