Abrasive Jet Casing Cutter(JCUTTER) • Run JCUTTER to casing cutting point • Pump abrasive slurry while rotating and moving cutter up and down • Trip out after cutting casing
Run-In After cutting casing run abrasive jet hole reamer (JREAMER)
After under-reaming move JREAMER upward to rotate nozzles back into tool cavity trip out of hole
JREAMER (Summary) Run-In Hole Extend Jets & Under-ream Retract Jets Trip out of Hole
JREAMER Reamed Section Ream a 30” dia x 10 ft. section 30” 10 FT.
JETDRILL Anchor The JETDRILL anchor is set using standard wireline or hydraulic setting tools
ORIENTATION GUIDE JETDRILL Orienting Guide A special guide that orients the JETDRILL to the proper angle for jet drilling is adjusted at the surface UNTAPPED Production
ORIENTATION GUIDE Slot for orientation lug 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 UNTAPPED Production
JETDRILL BENDING Additional compressive load actuates a unique articulated section, starting the 90 degree bend in the coil tubing UNTAPPED Production PIN PIVOT
Guide 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
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 TAPPED Production
JETDRILL can be retrieved and re-run at different angles with the same anchor setting NEW TAPPED Production

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
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
