ABC Bypass System (Y-Tools)
UK Patent No. GB2590029
The patented UMS Flowell ABC Bypass System is a simpler, faster installation than conventional y‐tool installations. No pre job space out is required with the ESP components, the bypass tubing minimum length is simply the ESP length plus fifteen feet.
The bypass tubing is installed first with conventional handling equipment and when complete, it is suspended in a hoist or two tiers worktable. The ESP is then installed with special bypass clamps which slide down the bypass tubing.
Finally, the Y‐tool is picked up and made up the ESP pump and lowered to allow the bypass swivel to be made up.
