Through-Tubing Completions Maximize Production

The challenge with through-tubing sidetrack completions has been dealing with small clearances and the lack of ready-made equipment. Over the last 10 years and after more than 450 coiled-tubing (CT) -drilling sidetracks on the North Slope of Alaska, a number of unique completion designs have been developed to maximize production and achieve vertical/zonal isolation.
