Abstract

Systems and methods for wireless telemetry in oil and gas wells use fluid pressure differentials to send signals from surface equipment to a downhole tool. More specifically, the methods and systems selectively apply fluid pressure to a tubing string and measure the resulting mechanical strain, or deformation, on a tubular of the downhole tool. The deformation may be an elastic deformation or it may be a plastic deformation with yielding of the tubular. One or more of such strains or deformations may be used to encode a digital signal that can command an action on the tool. The strain or deformation may be measured by a low-cost strain gauge.
