7.3 BHA Run Data Object

For StandardWITSML v2.0

The BHA run (BhaRun) data object is used to capture information about one run of a tubular string into and out of the hole. A “run” begins when the first component of the string—typically the bottomhole assembly (BHA)—is lowered below the rotary table on the trip into the hole, and ends when the final component of the string (typically the BHA) is above the rotary table on the trip out.

The type of data captured includes identifying information about the run itself and key statistics and calculated values for the operation performed (drilling, logging, etc.) during the run. Information about the tubular string used on the run is stored in the Tubular data object.
