摘要： 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.

摘要： A stimulation system configured for use in open-hole wells. The system may alternatively or additionally be configured for multi-zone stimulation applications. The system includes assemblies which employ techniques and configurations for isolating recovery screens downhole even without the presence of well casing. In this manner protection may be provided from dowhnole contaminants such as water which might otherwise leak in from adjacent formation layers.

摘要： A technique facilitates sand control in a wellbore. A lower completion and an upper completion are run downhole into the wellbore and deployed. The lower completion assembly employs a plurality of packers to isolate well zones. The lower completion assembly also has gravel pack ports which are independently opened to enable gravel packing of each individual zone via a tool run downhole. Additionally, the lower completion assembly has a production port in each zone. A shifting tool is employed to open the production ports and to enable production from the well zones.
