Abstract
The rate of release of a well treatment agent into a well may be controlled by introducing into the well a screen containing a well treatment composite having a well treatment agent and a support for the well treatment agent. The diameter of the substrate is less than the diameter of the opening of the screen of the screen assembly. Over time, the well treatment agent is released from the substrate and passes from the interior of the screen into the well.
