​​Inflatable Packer/Plug
​​​​​​​The Thru-Tubing Inflatable Retrievable Packer provides a means of performing remedial and stimulation operations without pulling the production tubing. An inflatable packing element on the packer is sized to pass through the production tubing, pack off the casing/liner below and then the equalized and deflated packer can be retrieved through the production tubing. The thru-tubing packer has a large expansion inflatable packing element so that it can run through small diameters, such as production tubing, and set in the casing/liner below the tubing
The Thru-Tubing Bridge Plug (TTBP) provides the ability totemporarily plug ffotuhs yraropmet :edulcni snoitacilppA.gnibut noitcudorpeht woleb gnisac eht of lower zone, selective acid or chemical treatments, fracturing of upper perforation intervals, isolation of sensitive zones during recompletions, orzonal isolations. The bridge plug can be run on coiled or threadedtubing, or on electric wireline. The plug is equalized, released and retrieved with either tubing, braided wireline, or slick line with a single trip in the hole

Applications​​​​​​​
High-pressure production or testing
Fracture stimulation jobs with anchored or floating tubing strings
Lower-zone isolation, using the packer as a bridge plug
Upper-completion workover without the need to unseat the packer
Chemical stimulation, inhibition, water shut off treatments
Selective well monitoring and testing
Hole hunting / leak testing

​​​​​​​Features, Advantages and Benefits
Well can be reworked without pulling the tubing string or introducing kill fluid
Packer can be run on coiled tubing as well as threaded tubing
Can be used in vertical, high-angle, and horizontal application
Provides excellent open-hole or cased-hole zonal isolation
Pressure can be equalized across the packer before it is released
