Systems and methods for subsurface oil recovery optimization

A non-transitory program carrier device for carrying computer executable instructions for long term oil recovery enhancement, the instructions being executable to implement:

• receiving first input corresponding to a selection of one or more zones, wells, patterns, clusters or fields;
• identifying a field development plan associated with the one or more selected zones, wells, patterns, clusters or fields, the field development plan corresponding to a sweep efficiency health indicator;
• displaying multiple scenarios and one or more long-term optimization actions corresponding to each scenario of the multiple scenarios, each of the one or more long-term optimization actions optimizing hydrocarbon fluid recovery for the one or more selected zones, wells, patterns, clusters or fields, each of the one or more long-term optimization actions being responsive to a predicted future condition, the multiple displayed scenarios and the corresponding one or more long-term optimization actions being ranked according to at least one of net present value, increased oil recovery, or reduced recovery of unwanted gas or fluids, and the ranking being based at least in part on real-time surveillance field data associated with the one or more zones, wells, patterns, clusters or fields;
• receiving second input corresponding to a selection of one or more of the multiple scenarios and displaying each corresponding long-term optimization action of the corresponding one or more selected scenarios;
• receiving third input corresponding to a selection of a prediction date for each selected scenario;
• executing a simulation for each selected scenario based on the prediction date, the execution of the simulation using one or more predictive models to predict a condition that is simulated to exist on the prediction date, the condition being associated with the one or more zones, wells, patterns, clusters or fields, and the condition resulting from each selected scenario existing for a period of time;
• selecting a long-term optimization action responsive to the simulated condition occurring on the prediction date, the long-term optimization action being selected from the one or more long-term optimization actions corresponding to one or more selected scenarios;
• updating, based on the predicted condition, the field development plan, the selected long-term optimization action responding to the predicted condition and causing the sweep efficiency health indicator to be modified, and the modified sweep efficiency health indicator representing an improvement over the sweep efficiency health indicator;
• and
• displaying, using one or more processors, each of:
• the one or more selected scenarios,
• an effect of the determined long-term optimization action on the prediction date, and
• the updated field development plan, the updated field development plan being displayed for the field with a respective net present value calculation and the modified sweep efficiency health indicator, and the updated field development plan including an updated schedule for infill and re-drilling of water injection positions.
