Toe Prep System
The Gator perforator can now be ran to cleanout and perforate failed toe sleeves in a single trip. This significantly lowers time between clean out and putting a well back onto production after stimulating. Additional tools such as a Mud motor and agitator can be ran in junction with the Gator to accommodate extended reach laterals.
- Run in hole to the toe of the well.
- Circulate on trip in as required to operate the Agitator, Mud Motor and Mill.
- Once on depth, drop 0.7" dia activation ball and pump to seat, closing the main bore and leaving the 6/32 nozzle open to below.
- Pump at 2 bpm and bring downhole differential pressure up to 4000 psi for a successful perforation.
- Kick out the pumps and allow the tool to equalize.
- Repeat the pressure up sequence of the Gator to fully perforate all clusters of the first frac stage.
- Once all perforations are complete, drop the MHA circulation ball and follow the activation procedure described by the manufacturer.
- Circulate as needed and pull out of the hole.
Bottom hole assembly
- MHA (Motor Head Assembly )
to disconnect lower BHA from coil if required. Ball Drop Circ for pulling out of hole and circulating. Double flapper for well control
- GATOR PERFORATOR
Hydro-Mechanical Perforator
More about the Gator Perforator → - Pressure Up Sub
to allow flow through the tubing. Once a ball is dropped, the BHA is closed except for a 6/32 bleeder nozzle and a full activation of the Gator can be made by pumping at 2 bpm. Bring downhole differential up to 4000 psi then kick out the pumps.
- Agitator
to provide a vibrating pulse to reduce tool friction on the trip in the hole
- Mud Motor
Positive displacement pump.
- BIT OR MILL
Customer specified bit or mill.
