JETDRILL Canister
A predetermined length of coiled tubing equal to desired lateral length is run inside a canister and the JETDRILL assembly is then run to bottom on a work string

JETDRILL COLLET
• The JETDRILL is oriented in the anchor
• Compressive weight engages a COLLET in the anchor

JETDRILL BENDING
Additional compressive load actuates a unique articulated section, starting the 90 degree bend in the coil tubing

JETDRILL ACTIVATION
• The coil tubing is released from the canister by rotating the work string
• Jet drilling is initiated while continuing to set weight on the coil tubing
• The coil tubing extends through the articulated body as weight is applied at the surface
UNTAPPED Production
23
TAPPED Production
The jet bits operating at 6,000 to 8,000 psi drill 3 to 4 inch diameter horizontal holes up to 300 ft long, to overcome formation damage and water coning problems, and to tap new production zones
24
NEW TAPPED Production
JETDRILL can be retrieved and re-run at different angles with the same anchor setting

JETDRILL Summary
• Erode casing section with JCUTTER
• Erode 30 in x 10 ft hole section with JREAMER
• Set JETDRILL ANCHOR at desired depth
• Run JETDRILL and orient in ANCHOR
• Apply weight to engage collet in ANCHOR
• Release coil tubing by rotation and initiate jet drilling. Continue to set-down weight on coil tubing until desired distance is drilled
• Pick up and retrieve JETDRILL assembly from well
27
JETDRILL Advantages
• Convert vertical wells to horizontal
• Drill multiple laterals from existing wells
• Increase production from existing wells
• Penetrate near wellbore damage
• Overcome water coning problems
• Intersect new production zones
• Short radius enables pinpoint accuracy
• Patent pending
