This paper will address how coiled tubing, combined with advanced acidizing technologies, can improve the ability to optimize treatment coverage in openhole completions. Two methods that have been very successful in the Permian and Anadarko Basins are foam and self-diverting acid systems. When acid is pumped into an openhole completion, it is difficult to determine precisely where the acid is going. It is vitally important to ensure that the entire interval is being treated adequately to optimize production. Coiled tubing and advanced acidizing technologies have shown tremendous promise with these stimulation techniques. This paper will also discuss the many techniques that have been attempted throughout the years with mixed results.
