Abstract: A method for measuring non-drilling times during well construction operations includes automatically determining a staring time and a stopping time of at least one non-drilling activity. An elapsed time between the starting time and the stopping time of the activity is recorded. The recorded time is normalized for at least one of a well depth and a water depth.
Abstract: A system for monitoring auxiliary operations on a drilling unit includes at least one sensor configured to measure a parameter related to a start time and a stop time of at least one auxiliary operation on the drilling unit. The system includes a data acquisition device configured to determine a start time and a stop time of the at least one auxiliary operation from measurements made by the at least one sensor. The data acquisition device includes a data recorder for recording elapsed time between the start time and the stop time.
