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.

Abstract: A method for evaluating multiple wells using water chemistry analysis may include testing a parameter associated with a first sample obtained from each of the wells over a period of time prior to implementing the field operation of the well. The method may also include generating a baseline of the parameter associated with the first samples for each of the wells. The method may further include testing the parameter associated with second samples obtained from each of the wells during the field operation of the well. The method may also include determining a difference in the parameter between the baseline and results of testing the second samples for at least one of the wells, where the difference exceeds a threshold parameter value for the parameter, and where the difference includes a characterization of water saturation.
