Plan Deviations Visualization and Interpretation
2 Dec 21
A method for conducting an oilfield operation includes obtaining a plan for conducting an oilfield operation, the plan including a planned value for a metric, receiving data collected while performing one or more oilfield activities using the plan, at least a portion of the data representing an actual value for the metric, determining that one or more deviations from the plan occurred based on a difference between the actual value and the planned value, identifying one or more unplanned events of the one or more oilfield activities that are not in the plan that caused the one or more deviations, calculating a contribution to the difference between the actual value and the planned value caused by the one or more unplanned events, and modifying the plan to account for the one or more unplanned events.
