Toe Sleeve


The FTS Frac Initiation Sleeve is designed for the Toe area of horizontal wells. The high-pressure rating gives the operator the ability to test the casing annulus, then increase pressure to hydraulically open. The tool can then be the first stage of the frac job through the large ports. The pressure setting to open the tool is adjustable using Burst Discs. A backup shear system is incorporated into the tool to prevent early opening. Using Dual Burst Discs, the tool provides a backup to insure opening at the desired pressure. Special Port Covers insure that the ports are not filled with cement or other debris that could prevent the piston from opening. When the tool is activated, these covers are removed.
