Abstract
This paper addresses the measuring techniques that involved data quality control and automatic drilling operations detections of routine drilling operations that are available today in modern drilling programs, and goes through examples of how implementation was carried out in the onshore area that drilled a series of similar wells. Measurement accuracy, training, and the development of new work processes were successfully implemented that led to major KPI (Key Performance Indicator) time savings between 31% and 43%. You cannot improve what you don't measure. And in this case you cannot measure without a proper data quality control (QC) procedure in place.
