Abstract:
1. A method of scheduling cyclic steaming of a plurality of petroleum-containing wells comprising: (a) inputting to a production-predicting means a plurality of data describing at least in part past cyclic steaming and resulting production of a plurality of petroleum-containing wells, wherein said production-predicting means comprises a computer-implemented component stored in a computer memory, and is processed in a computer processor in communication with said computer memory and a computer storage, an computer input and an computer output devices; (b) processing said data in said production-predicting means and outputting a plurality of production predictions for said plurality of wells during a future steaming cycle; (c) inputting said plurality of production predictions into an Optimal Cycle Length (OCL) scheduling means adapted and configured for varying t where t (d) inputting said plurality of production predictions and said initial steaming cycle schedule for said plurality of wells into an optimization means; (e) processing said plurality of production predictions and said initial steaming cycle schedule in said optimization means by the steps comprising:
