Operation:

The T- Nemec Frac Sleeve is designed for selectively stimulating multiple zones in either open or cased hole applications. The T-Nemec can be used in either vertical or horizontal wells usually in conjuction with the Lanch-HS Frac Sleeve and Vector-Pack and Vector Anchor Packers. The T-Nemec Frac Sleeve is activated by circulating a ball into a drillable seat inside the tool. Applied differential pressure from above the ball seat shifts the internal piston downward opening up the frac ports. The T-Nemec piston locks securely into place when in the downward position.
