This video of the month showcases how the application of FishVA, supported by Optis technology, helped an operator in Argentina overcome a fishing challenge and complete their unconventional well for subsequent production.
Despite the successful development of Argentina’s unconventional resources, many operators are being increasingly challenged with post-stimulation operational delays. Issues with wellbore access, resulting from frac hits and proppant bridges, are extending intervention schedules as additional plug millout and wellbore cleaning runs are required.
After having run several milling passes to rectify a collapsed casing interval, an operator in Argentina was hit with an unexpected setback – leaving a stuck mill downhole. Due to the pipe’s condition and the unknown orientation of the fish, attempting to recover the mill blindly was not an option for the operator.
EV’s Optis M125® camera, paired with EV’s FishVA service, was deployed on coiled tubing with downview video footage acquired to provide quantitative evaluation of fish location, geometry, orientation and status. The Optis® M125 camera was provided as the ideal option, as it could be conveyed via coiled tubing into the horizontal section with the ability to circulate fluid to ensure the acquisition of clear footage.
The high-definition video provided unique glimpse of the mill’s position inside the collapsed casing. The real value, however, was delivered by measurements from FishVA, which provided detailed measurements of the gap between the mill and the casing , allowing the operator to customize their fishing job. With this information, the operator was able to successfully retrieve the mill on the next attempt, and complete the well for subsequent production.
