Abstract
Systems and methods for subsurface secondary and/or tertiary oil recovery optimization based on either a short term, medium term or long term optimization analysis of selected zones, wells, patterns/clusters and/or fields.
Claims22
A computer-implemented method, comprising:
- receiving, using a processor, input corresponding to a selection of one or more zones, wells, patterns/clusters or fields of a hydrocarbon fluid reservoir, wherein the one or more zones, wells, patterns/clusters or fields is selected from a sweep efficiency health display, which comprises one of a current sweep efficiency health display and one of multiple predicted sweep efficiency health displays, and wherein the current sweep efficiency health display is based on current conditions data, which comprises real-time surveillance field data;
- receiving field data associated with the selected one or more zones, wells, patterns/clusters or fields, the field data representing one or more real-time conditions existing within the selected one or more zones, wells, patterns/clusters or fields;
- detecting an event using the field data associated with the selected one or more zones, wells, patterns/clusters or fields, the event representing a non-optimal condition of the selected one or more zones, wells, patterns/clusters or fields, and the non-optimal condition being below a performance threshold;
- determining whether a cause of the non-optimal condition is immediately resolvable, the immediate resolution of the cause including an action that is performed in real-time as a reaction to the detected event, and the resolution of the non-optimal condition causing the non-optimal condition to meet or exceed the performance threshold;
- in response to determining that the cause of the non-optimal condition is immediately resolvable, automatically selecting one or more scenarios from a plurality of scenarios, the plurality of scenarios being specific to the detected event, the selection of the one or more scenarios from the plurality of scenarios being based on the non-optimal condition, and each of the one or more selected scenarios corresponding to an action that optimizes the non-optimal condition in response to the detected event;
- displaying a visual representation of the one or more selected scenarios, the visual representation indicating the action corresponding to each selected scenario, wherein the displayed one or more scenarios and corresponding actions are ranked according to at least one of net present value, increased oil recovery, and reduced recovery of unwanted gas or fluids;
- receiving input corresponding to a selection of a scenario of the one or more selected scenarios;
- determining, using the processor, an effect on the non-optimal condition of the action corresponding to the selected scenario, the determined effect simulating an improvement of the non-optimal condition from below the performance threshold to above the performance threshold;
- displaying the action corresponding to the selected scenario;
- and automatically performing the action corresponding to the selected scenario, the performance of the action immediately resolving the non-optimal condition of the selected one or more zones, wells, patterns/clusters or fields, and the performance of the action improving a sweep efficiency health indicator of the hydrocarbon fluid reservoir.
