Mohawk Metal Patch

Casing, tubing or completion equipment in the wellbore may fail or deteriorate over the life of the well. This may occur due to corrosion, leaking tubular connections, or failed sliding sleeves. MetalPatchTM allows the failed area to be clad and sealed with minimal loss of inner diameter, while providing high burst and collapse ratings.

The MetalPatch product is designed to be deployed on tubing and cover long or short intervals ranging from 30 to 5,000 feet. Long patch lengths are reliably achieved with Mohawk’s proprietary expandable R2M connection. MetalPatch can also be deployed through various ID restrictions in the wellbore such as, nipples, frac sleeves, or mixed strings of heavy weight casing.

For applications requiring isolation from fracturing, the FracPatchTM system will be utilized. The FracPatch system relies on higher performing materials and a unique frac sealing system to handle high treating pressures as well as the induced loads from large temperature cool downs.

PRODUCTION IMPROVEMENT

  • > Perforation shut off
  • > Wellbore reduction for improved flow rate / ESP
  • > Water shut off
  • > Refrac

CASING INTEGRITY ISSUES

  • > Connection / Collar leaks
  • > Parted casing
  • > Casing corrosion
  • > Casing wear

COMPLETION FAILURES

  • > Leaking sliding sleeve
  • > Open frac sleeve
  • > Leaking frac valve
  • > Leaking DV tool

Stabbing

Anchor

PERFORMANCE

  • > Tubular material and geometries have been optimized for high burst and collapse ratings
  • > FracPatch specially designed to handle high pressures and large temperature changes

PASS-THRU CAPABILITY

  • > Patch can be deployed through various ID restrictions
  • > Patch can straddle frac sleeves or stray heavy weight casing joints

VERSATILE RUNNING TOOL

  • > Allows the patch to be expanded without the need to drop balls or darts down the ID of the workstring
  • > Redundant hydraulic cylinders capable of exerting high force for pipe expansion (3-4 times force required)

FULLY EXPANDABLE CONNECTIONS

  • > Proprietary R2M connections are designed to deliver high performance after expansion
  • > Connections do not require any pipe dope for "Rig Ready" makeup

NO DRILLOUT REQUIRED

  • > No shoes to mill up after expansion
  • > No debris left behind in the wellbore
  • > Patch deployed and expanded in one trip

HIGH TEMPERATURE RATING

  • > Premium elastomers available for temperatures over 300 degrees F
  • > Metal to metal seals also available for higher temperatures


Steps

The System Is Set In 5 Steps:

1. Make up the tool, expandable casing, work string, and RIH.
2. Initiate hydraulic expansion to set the lower seals.
3. Expand casing by pulling the work string.
4. Set upper seal by applying hydraulic pressure.
5. Pull out of hole.
