Abstract: Disclosed is a method for identifying opportunities for improvement in drilling and completions operations. At least one processor receives historical well data related to drilling and completions activities received from well monitoring sensors. The activities can include tripping, running casing, running bottom hole assembly, running riser, drilling connection operations, running screens, and running tubing. From the historical data, relative percentages of time spent on the activities are determined. Based on the relative time spent on each of the activities, a first priority activity is selected for improvement. A performance target for the first priority activity representing a value that can be calculated using well data received from the well monitoring sensors is determined. Real-time data is received from the well monitoring sensors. A current performance value using the real-time data is calculated and reviewed periodically to identify opportunities for improvement. Changes are implemented in an activity to improve the current performance value.
