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
slide10

Run-In

After cutting casing run abrasive jet hole reamer

(JREAMER)

JETDRILL Anchor

The JETDRILL anchor is set using standard wireline or hydraulic setting tools

JETDRILL Orienting Guide

A special guide that orients the JETDRILL to the proper angle for jet drilling is adjusted at the surface

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

slide19

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

slide21

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

slide22

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

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
slide26

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
