Abstract

A method for monitoring, predicting, and projecting a health status of a downhole tool in real-time includes determining whether a selected bottom hole assembly (BHA) run is performed using a drillstring operation or a coiled tubing drilling (CTD) operation. The BHA run includes a BHA in a wellbore, and the BHA includes a downhole tool. The method also includes receiving current parameters for the selected BHA run in a selected well. The parameters include (1) current first parameters that are independent of a performance of the selected BHA run using the drillstring operation or the CTD operation, and (2) current second parameters that depend upon whether the selected BHA run is performed using the drillstring operation or the CTD operation. The method also includes predicting a future health status of the downhole tool based upon the current first parameters and the current second parameters.

First claim

determining whether a selected bottom hole assembly (BHA) run is performed using a drillstring operation or a coiled tubing drilling (CTD) operation, wherein the BHA run comprises a BHA in a wellbore, and wherein the BHA comprises a downhole tool; receiving current parameters for the selected BHA run in a selected well, wherein the parameters comprise:
current first parameters that are independent of a performance of the selected BHA run using the drillstring operation or the CTD operation; and
current second parameters that depend upon whether the selected BHA run is performed using the drillstring operation or the CTD operation; and
predicting a future health status of the downhole tool based upon the current first parameters and the current second parameters.

2 . The method of claim 1 , further comprising determining and displaying a current health status of the downhole tool based upon the current first parameters and the current second parameters.

3 . The method of claim 1 , further comprising displaying the future health status of the downhole tool based upon the current first parameters and the current second parameters.

4 . The method of claim 1 , further comprising projecting and displaying the future health status of the downhole tool by simulating changes to the current first parameters and the current second parameters for the selected BHA run.

5 . The method of claim 4 , wherein the future health status is also projected by simulating future first parameters and future second parameters for future BHA runs with the downhole tool that have not yet occurred.

6 . A computing system, comprising:
one or more processors; and a memory system comprising one or more non-transitory computer-readable media storing instructions that, when executed by at least one of the one or more processors, cause the computing system to perform operations, the operations comprising:
determining whether a selected bottom hole assembly (BHA) run is performed using a drillstring operation or a coiled tubing drilling (CTD) operation, wherein the BHA run comprises a BHA in a wellbore, and wherein the BHA comprises a downhole tool;
receiving current parameters for the selected BHA run in a selected well, wherein the parameters comprise:
current first parameters that are independent of a performance of the selected BHA run using the drillstring operation or the CTD operation, and
current second parameters that depend upon whether the selected BHA run is performed using the drillstring operation or the CTD operation; and

determining a current health status and a predicted future health status of the downhole tool based upon the current first parameters and the current second parameters.

7 . The computing system of claim 6 , wherein the operations further comprise displaying the current health status and the predicted future health status of the downhole tool.

8 . The computing system of claim 6 , wherein the operations further comprise modifying one or more of the current first parameters and the current second parameters to improve the predicted future health status of the downhole tool or to improve an efficiency of operations even while consuming more of the predicted future health status of the downhole tool.

9 . The computing system of claim 8 , wherein the operations further comprise improving the predicted future health status by reducing a differential pressure for a mud motor in the BHA during future drillstring operations, or reducing a weight-on-bit (WOB) in the BHA during future CTD operations.

10 . The computing system of claim 8 , wherein the operations further comprise improving the efficiency of operations by increasing a differential pressure to thereby increase a rate of penetration (ROP) for a mud motor in the BHA during future drillstring operations, or increasing a weight-on-bit (WOB) in the BHA to increase the ROP during future CTD operations.

11 . A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a computing system, cause the computing system to perform operations, the operations comprising:
displaying a first list of wells; selecting one of the wells from the first list; displaying a second list of bottom hole assembly (BHA) runs in the selected well, wherein each BHA run comprises a BHA in a wellbore, and wherein the BHA comprises a downhole tool; selecting one of the BHA runs from the second list; determining whether the selected BHA run is performed using a drillstring operation or a coiled tubing drilling (CTD) operation; receiving current parameters for the selected BHA run in the selected well, wherein the parameters comprise:
current first parameters that are independent of a performance of the selected BHA run using the drillstring operation or the CTD operation, and
