Abstract
A technique utilizes micro-coil which is formed as a composite to enable use at substantial depths and/or with substantial flow rates. The micro-coil is formed as a tubing with a multi-layered tubing wall. The composite tubing wall provides substantial strength and longevity which allows deployment of the micro-coil in a much wider variety of well treatment applications, such as applications having substantial flow rates and/or applications at substantial well depths.
