Smart plug integrated sensor system

Abstract

A technique facilitates collecting data, related to a fracturing, run-in-hole, or pull-out-of hole operation. A frac plug is provided with electronics for obtaining the desired information related to the operation. For example, the frac plug may be constructed with electronic sensors, a digital storage device, and a power supply or other power related equipment. Depending on the application, the frac plug may be a composite frac plug, degradable frac plug, dummy frac plug, or other suitable frac plug. Retrieval of the information obtained may be done via coupling with an associated device, e.g. inductive or physical coupling, by utilizing a broadcast transmitter / receiver, by physical retrieval of the storage device, or by physical retrieval of the dummy frac plug.

Background technique [0003] Following the discovery of a desired subterranean resource, such as oil, natural gas, or other desired subterranean resource, drilling and fracturing operations are sometimes performed to facilitate access to the subterranean resource. During a fracturing operation, a frac plug may be deployed downhole and positioned at a desired location along the wellbore. Frac plugs allow pressure to be applied downhole and perforated into the surrounding formation, thereby fracturing the formation. To obtain information about the fracturing operation, relatively expensive external instrumentation is deployed and corresponding control lines are laid on the outside of the casing. However, external instrumentation...
