A method of scheduling cyclic steaming of petroleum-containing wells including: inputting to a production-predictor data describing the past cyclic steaming and resulting production of wells; processing the data in the production-predictor and outputting production predictions for the wells during a future steaming cycle; inputting the production predictions into an optimizer; inputting an initial steaming Optimal Cycle Length schedule for the wells into the optimizer; processing the production predictions and the initial steaming cycle schedule in the optimizer by: determining a ranking for the initial steaming cycle schedule for the production predictions against a pre-determined ranking criteria; producing new steaming cycle schedules based on the ranking of the initial steaming cycle a schedule optimization algorithm; determining a ranking for the new steaming schedules against the ranking criteria; repeating the production of schedules and determining ranking steps until some pre-determined termination criteria is met.
