Identifying breakover events using rig sensor measurements with associated rig state determination

A method for identifying a breakover event of a drill rig, the method comprising:

• receiving a low frequency rig sensor data stream of the drill rig, the low frequency rig sensor data stream including rig sensor measurements, the low frequency rig sensor data stream having a monitoring frequency;
• identifying a rig state of the drill rig from the low frequency rig sensor data stream, the rig state including a movement state;
• when the movement state includes movement after a static state, retrieving a high frequency rig sensor data stream of the drill rig from a cache, the high frequency rig sensor data stream having an analysis frequency that is greater than the monitoring frequency;
• and
• identifying, based on the high frequency rig sensor data stream, a breakover profile to identify the breakover event.

A drilling system, comprising:

• a plurality of rig sensors that measure a rig sensor data stream with a measurement frequency;
• and
• a processor and memory, the memory including instructions that cause the processor to:
• monitor, with a monitoring frequency, the rig sensor data stream to identify a rig state of a drill rig, the measurement frequency greater than the monitoring frequency;
• store the rig sensor data stream in a cache of the memory for a cache period;
• when the rig state includes a movement state after a static state, retrieve the rig sensor data stream from a cache for the cache period;
• and
• identify, based on an analysis frequency of the rig sensor data stream, a breakover profile of a breakover event experienced by the drill rig, the analysis frequency greater than the monitoring frequency.
