Abstract
A stimulation technique is provided for use in an open hole well. The stimulation technique utilizes a system which comprises one or more isolation devices positioned to isolate desired regions of the open hole well. At least one release mechanism is used to provide controlled release of stimulation material to a desired wellbore region of the open hole well. Additionally, a protection mechanism cooperates with each release mechanism to prevent undesirable contact between stimulation material and the surrounding wellbore wall of the open hole well. In many applications, the entire system is deployed and operated during a single trip downhole into the well.
