Downhole tool system and method for use of same
First Claim
1. A downhole tool system comprising:
- a downhole tool operably positionable within a wellbore;
a sensor positioned within the downhole tool, the sensor having a first mode and a second mode, in the first mode, the sensor is responsive to RF interrogation, in the second mode, the sensor is not responsive to RF interrogation, the sensor operable to transition from the first mode to the second mode upon the occurrence of a predetermined level of erosion of the downhole tool proximate the sensor; and
a detector operably positionable relative to the downhole tool in communicative proximity to the sensor, wherein the detector interrogates the sensor to determine whether the predetermined level of erosion has occurred.

Abstract
A downhole tool system includes a downhole tool operably positionable within a wellbore and a sensor positioned within the downhole tool. The sensor has a first mode and a second mode. In the first mode, the sensor is responsive to RF interrogation. In the second mode, the sensor is not responsive to RF interrogation. The sensor is operable to transition from the first mode to the second mode upon the occurrence of a predetermined level of erosion of the downhole tool proximate the sensor. A detector is operably positionable relative to the downhole tool and in communicative proximity to the sensor. The detector interrogates the sensor to determine whether the predetermined level of erosion has occurred.

7. A downhole tool system comprising:
-
a downhole tool operably positionable within a wellbore; a plurality of sensors embedded within the downhole tool, each of the sensors having a first mode and a second mode, in the first mode, the sensors are responsive to RF interrogation, in the second mode, the sensors are not responsive, the sensors are operable to transition from the first mode to the second mode upon the occurrence of a predetermined level of erosion of the downhole tool proximate the respective sensors; and a detector operably positionable relative to the downhole tool in communicative proximity to the sensors, wherein the detector interrogates the sensors to determine whether the predetermined level of erosion has occurred and if so, the location of the predetermined level of erosion based upon which of the sensors are not responsive. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A downhole method comprising the steps of:
-
disposing a downhole tool within a wellbore, the downhole tool having a sensor positioned therein, the sensor having a first mode in which the sensor is responsive to RF interrogation and a second mode in which the sensor is not responsive to RF interrogation, the sensor operable to transition from the first mode to the second mode upon the occurrence of a predetermined level of erosion of a surface of the downhole tool; flowing a fluid through the downhole tool; after flowing the fluid through the downhole tool, running a detector into the wellbore such that the detector is in communicative proximity to the sensor; interrogating the sensor with the detector; and determining whether a predetermined level of erosion of the downhole tool has occurred based upon the responsiveness of the sensor. - View Dependent Claims (15, 16, 17, 18, 19, 20)
