These system components when used in conjunction with the ISOPAX Slimline ESP Packers allows full ESP system with penetrator to be installed inside 4-1/2” tubing sizes and above. The ISOPAX Slimline ESP Packers are among the slimmest on the market, helping them glide through the doglegs common in hastily drilled wellbores.
Their narrow profiles also enable them to pass through side-tracks to revive production in nonproducing wells and create options for the operator to manage their old well stock and revitalize brown field or shut-in wells. They can also be run in larger casing sizes for multizone production and for injecting and producing through the same wellbore. The process is fast, reliable, and can be carried out under live-well conditions—eliminating the need to kill the well. The thru-tubing system is deployed through a surface lubricator and lowered inside the existing production tubing. The thru-tubing completion system can be easily retrieved using only the ESP cable. So, it can be used temporarily to keep production flowing and then removed when a replacement ESP arrives. Or it can be left in hole permanently as the replacement, providing a way to extend the economic life of wells that would otherwise be plugged and abandoned due to workover and rig costs. This technology also reduces health and safety risks. Instead of the full crew needed to run a rig during tubing-deployed completion replacement, the Thru-Tubing system can be deployed with only three or four onboard personnel.
