Series 5100 Inflatable Circulating or Squeeze Gravel Pack System

The TTS Series 5100 Circulating Thru-Tubing Gravel Pack System utilizes a retrievable Inflatable Packer, Two-Position Crossover Tool, Lower Gravel Pack Perforated Extension with closing sleeve and wash pipe, in order to accomplish a one trip coiled tubing deployed circulating Thru-Tubing Gravel Pack. This system allows for deployment of the GP BHA on coiled tubing, as well as Setting and testing of packer prior to pumping of the gravel pack slurry. The Two-Position Crossover Tool allows for circulating Below the Packer (lower circulating or gravel packing position) and an upper circulating or reverse position for spotting fluids, reversing or circulating above the packer. The upper position establishes isolation from the producing interval for guaranteed Circulating above the Gravel Pack Packer for removing excess slurry from the work string regardless of BHP. Upon completion of the gravel pack pumping operation, a closing sleeve is installed to isolate the ports in the Gravel Pack Perforated Extension. This is accomplished by removal of the Crossover Tool and Wash Pipe Assembly when POOH.

Applications

• Repair of failed Cased Hole Gravel Pack.
• Installation of Circulating or Squeeze Gravel Pack in wellbores where no sand control system currently exist.
• Installation of Thru-Tubing Gravel Pack where wellbore restriction may exist.
• Thru-Tubing Gravel Pack installation where installation is to be set in a larger I.D. tubing than deployed through

Features/Benefits

• Allows for repair of cased hole gravel pack without the expense of a workover rig. “Saves time and cost compared to conventional workovers”
• Inflatable packer system allows for setting of TTGP packer below the end of the production tubing. Negates problems associated with production tubing movement. Goes not interfere with future plug backs when production tubing removal is required. Enables shortening of TTGP assembly.
• One trip installation. Does not require additional trips in well to install anchoring or sealing accessories.
• Allows for a circulation or squeeze type Gravel Pack. Better accommodates inflow performance over typical pre-packed screen hang-off.
• Isolation sleeve positively closes and seals off GP Perforated Extension below packer. Eliminates time and cost associated with additional trips into the well needed to install additional sealing accessories.
• Ability to test all sealing and anchoring components prior to gravel packing. Allows for positive pressure test and assurance of proper packer placement.
