Mix Master
The Mix Master is designed to effectively isolate the surface equipment while fracturing down the annulus with the tubing as a dead leg or both annulus and tubing. The Mix Master provides a mandrel and patented sealing assembly mounted on the bottom end for pack-off in the casing of the well to be stimulated. The Mix Master is locked into place with a lockdown nut that prevents upward movement by fluid pressures from within the well bore.
Features
- Eliminates killing the well as the tool can be installed and removed under pressure
- Reduces rig time since there is less tripping of pipe
- Generally eliminates snubbing
- Packer not required
- Allows flow-back for cost effective cleanout
- Permits circulation of sand for cleanout via tubing or annulus
- Allows for the installation of perforating guns prior to tool installation
- Full bore tubing facilitates swabbing and running down hole equipment
- Can only be removed under pressure with a class 3 BOP system
- A working platform is provided with the tool. The platform is complete with handrails and ladder for easy access.
- Additional stairs can be attached and are available upon request
Specifications
Pressure rating: 69 Mpa (10,000psi) working pressure
Sizes
- Casing: 4-1/2” (114mm) to 9-5/8” (244mm)
- Tubing: 2-3/8” (60.3mm) to 2-7/8” (73mm)
Maximum Pumping Rates
- 3 m3/min. for 2-3/8” tubing and 4-1/2” casing
- 6 m3/min. for 2-7/8” tubing and 5-1/2” casing
- 8 m3/min. for 2-3/8” tubing and 5-1/2” casing
Higher rates can be achieved by pumping down both the annulus and tubing
