It is often necessary in the management of a modern reservoir to alter the completion interval in a well. These adjustments are needed to modify producing well fluid ratios such as water-oil ratio or gas-oil ratio. One way to minimize the cost associated with completion interval adjustments is to design a well that can change the completion interval automatically. This is an example of an intelligent well, which is also known as a “smart well.”
Intelligent wells are designed to give an operator remote control of subsurface well characteristics such as completion interval. In addition, intelligent wells are being designed to provide information to the operator using downhole measurements of physical properties such as pressure, temperature and seismic vibrations. One goal of intelligent well technology is to convey a stream of continuous and real-time information to the operator who can monitor this information and make adjustments as needed to achieve reservoir management objectives.
