Abstract

A computer-implemented process simulates production of oil and gas from hydrocarbon reservoirs. The process is used to help forecast the optimal future oil and gas recovery from large hydrocarbon reservoirs. At the same, this process is flexible to allow for further addition of new options; robust and reliable; and easy to use. The process is also comprehensive in that it allows a forecast of future performance of a wide range of reservoirs and future operation scenarios. By using the high-resolution models provided, a reservoir can be described much more accurately.

Claims

1. A computer-implemented method of analyzing performance of a hydrocarbon reservoir for prediction of future production of hydrocarbon fluids from wells in the reservoir, comprising the steps of;

establishing in the computer a set of production rules for a well in the reservoir;

processing performance data in the computer for the well, to determine production results;

comparing the determined production results in the computer with the established set of production rules;

identifying in the computer those production results for a well which violate at least one of the established set of production rules so that corrective action may be taken.

2. The method of claim 1, wherein the step of establishing a set of production rules comprises the step of establishing in the computer a set of production rules for a number of completions in the well.

3. The method of claim 2, wherein the step of processing performance data comprises the step of processing performance data in the computer for a number of completions in the well.

4. The method of claim 3, wherein the step of identifying production results comprises the step of identifying in the computer those production results which violate at least one of the established set of production rules for the number of completions in the well.

5. The method of claim 1, wherein the step of establishing a set of production rules comprises the step of establishing in the computer a set of production rules for a number of completions in wells in the group of wells.

6. The method of claim 5, wherein the step of processing performance data comprises the step of processing performance data in the computer for a number of completions in wells in the group of wells.

8. The method of claim 1, wherein the step of establishing a set of production rules comprises the step of establishing in the computer a set of production rules for the wells in the reservoir.

9. The method of claim 8, wherein the step of processing performance data comprises the step of processing performance data in the computer for the wells in the reservoir.

10. The method of claim 9, wherein the step of identifying production results comprises the step of identifying in the computer those production results which violate at least one of the established set of production rules for the wells in the reservoir.
