To accomplish this a means of temporarily pluggingthe tubing below the packer must be provided. Example: Run a WELLCARE Hydro-Trip PressureSub, below the ―WC-HP-1‖ Hydrostatic/Hydraulic Packeror a WELLCARE Flow Control Seating Nipple installed at MODEL: WC-HP-1some point below the packer, with a Blanking Plug run and PRODUCT NO.: WC-20101retrieved by standard wireline techniques. Wireline Re-Entry Guide with Pump-Out Plug or Ball Seat can also beused to blank off tubing. If more than one ―WC-HP-1‖Hydrostatic/Hydraulic Packer is to be run, place the tubingplugging device below the lowest packer. When the tubingis pressured in this case, all of the hydrostatic packers willbe set simultaneously. If it is desirable to individually setand test each packer, the Model ―WC-HP-1‖Hydrostatic/Hydraulic Packer is adaptable to individualsetting and testing by a simple adjustment of shear screws inthe segment retainer housing. Dress the lowest packer withtwo brass shear screws. When dressing packers for this typehook-up, all packers going on one string should be dressedwith shear screws from one box to ensure similarity of shearvalues. Dress the second (middle packer in three-packerhookups, or upper in two-packer hookups) with five brassshear screws, and a third (upper) packer with eight brassshear screws. This allows the packer to be set individually.The first will set with approximately 1,000, the second2,000 and the third 3,000 psi differential at the packer. Inorder to test the packers individually, a means of temporarycommunication between the tubing and the casing (i.e. aSliding Sleeve below each packer) will be necessary. The 9

No. WC-20105 The Model ―WC-HP-3‖ is a pure Hydraulic SetPacker that can be run in single or multiple zoneinstallations. It is highly recommended for deviated wellswhere conditions are not suitable for Mechanical or Wireline Set Packers.Features/Benefits:-  No tubing movement is required for setting the Packer. This allows the well to be kept positively controlled at all times because the tubing is landed before circulating or displacing well fluids prior to setting the packer. Two or more packers can be set together or in any desired sequence.  The ―WC-HP-3‖ Packer design features four bi- MODEL : WC-HP-3 directional, single piece slips located below a three PRODUCT NO. WC-20105 element packing system consisting of dual durometer rubber elements. The slips are fully enclosed in a shear pinned slip housing which is protected by a full diameter guide located below the slip housing.  Two balanced pistons are utilized during the setting of the Packer. The lower piston moves down to set and anchor the slips while the upper piston moves upward to compress the packing element. This action imparts the entire setting force to both slips and packing thus assuring a positive anchor and pack-off. The pack-off is retained by a tapered single ratchet ring that locks in and stores the setting force applied to both the slips and packing element.  The ―WC-HP-3‖ Packer incorporates two methods of release. Straight pull or rotation. Both methods are done by the same releasing nut which is located at the upper end of the Packer. Straight pull release is accomplished by shearing retaining screws of a predetermined quantity which frees the tubing. Rotation release is accomplished by approximately eight right hand turns of the Tubing which also frees the Packer. Straight pull is then applied to completely relax the Packer for retrieval. An equalizing valve is also located in the releasing portion. The positive acting valve is automatically SPECIFICATION DATA opened during the releasing procedure to equalize pressure and allow circulation between the annulus Casing Packer and Tubing.
