This paper focuses on the application of radio-frequency-identification (RFID) technology to enable an operator to eliminate an intervention run (or intermediate liner) for a 10,000-ft reservoir section. The case-study well has preperforated liner in two zones isolated with swellable packers and pressure-actuated annulus packers. The typical procedure is to straddle the annulus packers individually using an inflatable plug, but setting the lower annulus packer incurs additional risk while running in the horizontal for an extended distance. Here, an RFID-actuated reservoir-isolation valve (RIV) eliminates an intervention run.
Methodology
RFID is now a common technology used across various industries to provide a means of communication between a passive antenna and an active antenna.
