Mix Master Tool
WELLSITE SERVICES COMPANY
Description:
The Stinger Mix Master Tool is designed for high-pressure injection stimulations to
isolate and protect surface wellhead equipment while fracturing down the annulus
and monitoring pressure in the tubing.
Specifications:
Pressure Rating: 69 MPa (10.000 psi) working pressure
Size specifications:
Casing: 114mm (4 ½”) to 244mm (9 5/8”)
Tubing: 60.3mm (2 3/8”) or 73mm (2 7/8”)
Maximum Pumping Rates:
3 m³/min. for 2 3/8” tubing & 4 1/2” casing
6 m³/min. for 2 7/8” tubing & 5 1/2” casing
8 m³/min. for 2 3/8” tubing & 5 1/2” casing
Higher rates can be achieved by pumping down both the annulus and the tubing.
Features:
1. Eliminates killing the well as the tool can be installed and removed under pressure.
2. Reduces rig time since there is less tripping of pipe.
3. Generally eliminates snubbing.
3. Packer not required.
4. Allows flow-back for cost effective cleanout.
