The tight margin nature of shale gas plays puts the pressure on operators to strike that optimal balance between cost and production gained. This effect is magnified by the ‘manufacturing mode' mentality that operators are striving for to get the most wells in the ground efficiently, cheaply, effectively, and safely as possible. This approach of course extends to every operation in shale gas completions, including coiled tubing plug drill-outs (CTDOs). This paper reviews one operator's quest to achieve this ‘balance' in CTDO operations as well as overcome technical challenges in two different shale gas plays - the Haynesville and Eagle Ford Shales.
