Abstract (en)
[origin: WO2016019077A1] 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.
