Abstract
Systems and methods use enhanced flow control devices that can be selectively closed completely or have its effective flow area reduced to restrict production (or injection) by use of a chemical trigger mechanism. In addition, some of the systems deploy specific targeted chemical tracers, dissolvable in the unwanted production fluid (e.g., water or gas). These chemical tracers once dissolved will enter the production stream and be identified at the surface. An appropriate chemical trigger can be placed, for example, by pumping down through the tubing and utilizing intelligent completion valve to place the chemical, or by spotting with coiled tubing and bullhead to the formation. The chemical trigger will only trigger the active chemical in the appropriate flow control device.
