Stradasnap Packer
The Stradasnap Packer consists of a modified Snapset II Packer combined with an AS-III Packer. A Stradasnap Packer is used for selectively treating short intervals of casing perforations to evenly break down the entire formation. The span covered is determined by the spacing between the two sets of packing elements and is adjustable to any distance down to eighteen inches.
The bottom of the Stradasnap Packer is plugged by using an Equalizing Standing Valve (or similar device). A Spot Control Valve or Acid Valve can be run above the Stradasnap Packer to control the tubing hydrostatic pressure across the perforations and contain the acid in the tubing when moving the packer to another perforation.
After locating the Stradasnap Packer across the lower most perforation, the Stradasnap Packer is set and the perforation is treated. Straight pick-up of the tubing releases the Stradasnap Packer to be moved up to the next perforation. Repeat the setting procedure to reset. When retrieving the Stradasnap Packer, retrieve the Spot Control Valve or Acid Valve so that tubing fluid can be dumped through the ports between the packing elements to prevent pulling a wet string.
