Description

The Evolution Model RC-2 Hydro-Grip Packer is a set-down packer with button-type hold-down and built-in unloader. It is used for pressure acidizing, formation fracturing and other squeeze operations.

Running Procedure

1. Make the Model RC-2 Hydro-Grip up on the tubing string and run to setting depth. The unloader will automatically be in the open position. This permits free circulation around the tool during running in and prevents the hold-down buttons from dragging against the casing.

2. To set the Model RC-2 Hydro-Grip run the packer to one foot below setting depth, pick up to setting depth, and then rotate the tubing to the right ¼ turn at the tool while lowering. The application of set-down weight closes the unloader, sets the slips, and packs off the Packing Element. At a temperature of 70° F., the table to the left shows the forces required to pack off.

NOTE - The 90 – Hard Packing Element will be considered the standard Packing Element on the size 28. The 80 – Hard Packing Element should be used only when the available set-down weight, as the tool is insufficient to pack off a 90 – Hard Packing Element. The Size 28A High Temperature tool uses a 90 – Hard Element and has increased diameters on Gage and Guide Rings.

3. When the pressure differential is in favor of the tubing, the hold-down buttons are forced out against the casing, thus preventing the tool from moving up the hole.
