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.

First claim

What is claimed is:

1 . A system for obtaining information during a downhole operation, comprising:
a disposable frac plug having sensors for obtaining data during a fracturing operation, the disposable frac plug further comprises a removable cartridge with a memory module, and the data from the sensors is stored in the memory module, the removable cartridge further comprises a removable cartridge latch; and a data transfer system by which the data obtained via the sensors is capable of being provided to a surface location with a wireline deployed downhole separately from the disposable frac plug, wherein the wireline comprises a wireline latch, and the wireline latch is configured to engage the removable cartridge latch for retrieval of the removable cartridge at the surface location.

2 . The system as recited in claim 1 , wherein the sensors comprise a temperature sensor.

3 . The system as recited in claim 1 , wherein the sensors comprise a pressure sensor.

4 . The system as recited in claim 1 , wherein the disposable frac plug comprises a power source for powering the sensors.

5 . The system of claim 1 , wherein the sensors are configured to obtain the data during a run-in-hole operation.

6 . The system of claim 1 , wherein the sensors are configured to obtain the data during a pull-out-of-hole operation.

7 . A method, comprising:
providing a plug with at least one sensor, wherein the plug further comprises a removable cartridge with a memory module, and data from the at least one sensor is stored in the memory module, the removable cartridge further comprising a removable cartridge latch; running the plug into a borehole and collecting data with the at least one sensor, wherein collecting data with the at least one sensor comprises deploying a wireline with a wireline latch; engaging the removable cartridge latch with the wireline latch; and retrieving the removable cartridge at the surface.

8 . The method of claim 7 , wherein the collecting data step occurs during the running step.

9 . The method of claim 7 , wherein the collecting data step occurs during the retrieving step.
