A major operator in the Gulf of Mexico was faced with debris build-up behind a concentric gravel pack string. In order to remove the debris using a chemical wash, multiple slots or holes in the concentric string were needed. Due to the close proximity of the gravel pack screens, the conventional method of using explosive perforating charges was not a reliable option due to the risk of damage.

Baker Hughes, a GE company (BHGE), recommended the MPC™ InCision slot cutter to provide the precise cuts needed to allow the operator access to the debris without causing any damage to the outer screens.

Challenges & Results
X

Challenges

  • Deepwater well
  • Reduced flow rates from concentric gravel pack due to asphaltine build-up
  • Risk to damage of gravel pack screens behind pipe

Results

  • 37 precise slot cuts made over 150 ft (46 m) section, allowing access to the debris blocking the screens
  • Reduced NPT, risk, and overall intervention costs
