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.
Claims28
A method for long term oil recovery optimization, which comprises:
- selecting one or more zones, wells, patterns/clusters or fields 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;
- displaying multiple optimization scenarios and corresponding actions for optimization of the one or more selected zones, wells, patterns/clusters or fields during an evaluation of a plan for developing a field;
- selecting one or more of the optimization scenarios and displaying each corresponding action;
- selecting a prediction date for each selected optimization scenario;
- and
- displaying the one or more selected optimization scenarios, the effect of each corresponding action on the one or more selected zones, wells, patterns/clusters or fields on the prediction date, and an updated field development plan using a computer system, the updated field development plan being displayed for a field with a respective net present value calculation and projected production parameters and wherein the display of the one or more selected optimization scenarios and the effect of each corresponding action includes infill drilling and re-drilling of water injection positions.

A non-transitory program carrier device tangibly carrying computer executable instructions for long term oil recovery optimization, the instructions being executable to implement:
- selecting one or more zones, wells, patterns/clusters or fields, 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;
- displaying multiple optimization scenarios and corresponding actions for optimization of the one or more selected zones, wells, patterns/clusters or fields during an evaluation of a plan for developing a field;
- selecting one or more of the optimization scenarios and displaying each corresponding action;
- selecting a prediction date for each selected optimization scenario;
- and
- displaying the one or more selected optimization scenarios, the effect of each corresponding action on the one or more selected zones, wells, patterns/clusters or fields on the prediction date, and an updated field development plan, the updated field development plan being displayed for a field with a respective net present value calculation and projected production parameters and wherein the display of the one or more selected optimization scenarios and the effect of each corresponding action includes infill drilling and re-drilling of water injection positions.
