摘要： A technique utilizes micro-tubing to facilitate performance of a well treatment in which the micro-tubing is deployed for cooperation with a larger tubing, such as a coiled tubing positioned in wellbore. The micro-tubing is used to deliver a separated chemical downhole to modify a property of a treatment fluid used in performing a desired well treatment operation at a desired treatment region along the wellbore. A variety of additional components may be combined with the micro-tubing to further facilitate the treatment application.
