HYDRAULIC SET HIGH PRESSURE HIGH ANGLE PRODUCTION PACKER
This is a Hydraulic set high pressure high angle production packer that can be run in single or multiple zone installations. It is highly recommended for deviated wells where conditions are not suitable for mechanical or wireline set packers. No tubing movement is required or generated in order to set the packer. This allows the well to be kept positively controlled at all times because the tubing is landed and the wellhead installed before circulating or displacing well fluids prior to setting the packer. Two or more packers can be set either at once or in any desired sequence. Packer design features bi-directional, one piece slips located below a three element packing system consisting of dual durometer rubber elements. The slips are fully enclosed in a shear pinned slip housing which in turn is protected by a full diameter guide located below the slip housing. Two balanced pistons are utilized during the setting process. The lower piston moves down to set and anchor the slips while the upper piston moves upward to compress the packing. This action imparts the total setting force to both slips and packing thus assuring a positive anchor and pack-off. The pack-off is retained by a single ratchet ring that locks in and stores the setting force applied to both the slips and packing elements.
