Abstract

According to one embodiment, there is provided herein a system and method for producing a well lifecycle lift plan that includes considerations of multiple types of lift, multiple lift configurations associated with each lift type, and can be used to provide a prediction of when or if it would be desirable to change the lift plan at some time in the future. Another embodiment utilizes a heuristic database with rules that might be used to limit the solution space in some instances by restricting the solution to feasible configurations. A further embodiment teaches how multiple individual well optimization results might be combined with a reservoir model to obtain an optimized lift schedule for an entire field.

First claim

What is claimed is:

1. A computerized method of managing production in a hydrocarbon producing well, comprising the steps of:
a. accessing a decline curve for the well, said decline curve predicting hydrocarbon production from the well over a predetermined period of time;
b. accessing a lifecycle plan for the well, said lifecycle plan specifying a use of at least two different lift methods and containing at least one changeover point, each of said at least one changeover points occurring a time within said predetermined period of time;
c. forming a graphical representation on a display device of said decline curve and said lifecycle plan, wherein each of said at least one change over points is represented by a graphical indicium on said display device;
d. displaying at least one of financial information associated with lifecycle plan and production information associated with said lifecycle plan;
e. allowing a user to select on said display device one of said graphical indicium associated with one of said at least one changeover points;
f. allowing a user to adjust on said display device a time location of said selected changeover point, thereby producing a modified lifecycle plan for the well;
g. using at least a portion of said lifecycle plan to calculate and display on said display device in real time a modified financial information associated with said lifecycle plan if said financial information was displayed or a modified production information if said production information was displayed; and,
h. making at least one lift decision in the well using said modified lifecycle plan.

2. The computerized method of managing production in a hydrocarbon producing well according to claim 1 , wherein said financial information includes at least one of a predicted net present value of an income stream for said lifecycle lift plan, a total equipment cost for said lifecycle lift plan, and an income statement for said lifecycle lift plan.

3. The computerized method of managing production in a hydrocarbon producing well according to claim 1 , wherein said production information includes at least one of a total fluid production, an oil production, a gas production, a down time, a quantitative risk, or a technical feasibility score.

4. A multilevel computerized method of managing production in a hydrocarbon producing well, wherein is provided a computer display, comprising the steps of:
a. accessing a decline curve for the well, said decline curve predicting hydrocarbon production from the well over a predetermined period of time;
b. accessing a plurality of lifecycle plans for the well,
wherein each of said plurality of lifecycle plans has an objective function value associated therewith,
wherein each of said plurality of lifecycle plans specifies a use of at least two different lift methods during said predetermined period of time, and,
wherein each of said plurality of lifecycle plans specifies a changeover point between each of said at least two different lift methods;

c. selecting a number of said plurality of lifecycle plans to display;
d. presenting on said computer display an ordered list of said selected number of lifecycle plans with said selected number of lifecycle plans being ordered based on each lifecycle plan's objective function value;
e. allowing a user to select one of said number of ordered lifecycle plans;
f. for said selected lifecycle plan, forming a graphical representation on a display device of said decline curve and said lifecycle plan, wherein each of said at least one change over points is represented by a graphical indicium on said display device;
h. displaying at least one of a financial information associated with lifecycle plan and a production information associated with said lifecycle plan;
i. allowing a user to select on said display device one of said graphical indicium associated with one of said at least one changeover points;
j. allowing a user to adjust on said display device a time location of said selected changeover point, thereby producing a modified lifecycle plan for the well;
k. using at least a portion of said lifecycle plan to calculate and display on said display device in real time a modified financial information associated with said lifecycle plan if said financial information was displayed or a modified production information if said production information was displayed; and,
l. making at least one lift decision in the well using said modified lifecycle plan.

5. The method of claim 4 , wherein step (h) comprises the steps of:
(h1) displaying at least one of a financial information associated with lifecycle plan and a production information associated with said lifecycle plan, and,
(h2) displaying on said display device configuration details for each of said at list two different lift methods associated with said selected lifecycle plan.

6. The method of claim 4 , wherein said objective function value is selected from the group consisting of a net present value, a cash flow total, and an operating cost.
