CT L FAST Shifting Tool

Reduce water cut by identifying and shutting off water producing zones with the DTI ‘L’ Hydraulic Shifting Tool. The DTI ‘L’ Hydraulic Shifting Tool is used to selectively open and close multiple drop ball type Stimulation or Frac Sleeves in a single CT trip. By flow testing during the operation, the water producing zones can be identified and water producing Sleeves can be closed. The Shifting Keys are unsupported during the running operation so that they will pass through Ball Seats. When the pump rate is increased the Shifting Keys are locked into the expanded shifting position and a Stimulation Sleeve may be shifted upwards to close (or downwards to open).

The L FAST is choked so that by increasing the pump rate an increased back pressure is achieved at the tool.
