WWT FlexShoe Guides Liner into the Sidetrack on the First Attempt.

A sidetrack-configured WWT FlexShoe, model FLX-550 ST, was picked up and run at the bottom of the casing. This FlexShoe uses a small amount of weight at the end of the FlexShoe, deflecting the shoe down into a low side sidetrack without the need to orient the casing while still maintain effectiveness as a guide shoe. The WWT FlexShoe guided the 5-1/2” casing into the low-side sidetrack KOP on the first pass and without any noticeable drag. The casing then continued to TD without any problems.

WWT FlexShoe and Casing Floatation Equipment

The WWT FlexShoe worked well with the casing floatation equipment used on this well. Because the WWT FlexShoe can minimize loading when running past ledges and other downhole obstructions, it can reduce the need for working the string when rotation may take time and generate substantial torque, and circulation/washing casing down is not an option.
