Due to superior efficiency, the Well Tractor and Well Miller® were selected to remove barium sulfate build-up inside the wellbores. Extensive testing before mobilization led to two mill sizes being chosen: 3.8” to open up through the scale and 4.2” run to give the required final ID.
A total of 42 ft of barium sulfate scale was successfully removed from two wells in 12 days – the same time it would have taken just to rig up/down the coiled tubing equipment offshore.
Full access to the reservoir was re-established for future operations and the operation eliminated heavy lift requirements.
INCREASED PRODUCTION: ADDITIONAL FOUR MILLION CUBIC FT OF GAS/DAY
