Claim 5:
6. A method of operating a drilling tool, the method comprising:
generating synthetic data for rate of penetration, weight-on-bit, and rotations-per-minute using real-time data associated with the drilling tool, the synthetic data including, outside a values of the real-time data, optimized values for the rate of penetration, the weight-on-bit, and the rotations-per-minute;
combining the synthetic data with the real-time data to form combined data;
training a rate of penetration model using the combined data to produce a trained rate of penetration model, wherein the trained rate of penetration model comprises a recurrent generative adversarial network (RGAN);
projecting a value for the rate of penetration per drilling sequence using stochastic optimization of the trained rate of penetration model subject to range constraints;
projecting corresponding values for weight-on-bit and rotations-per-minute using the trained rate of penetration model; and
steering the drilling tool using the corresponding values for at least one of the weight-on-bit or the rotations-per-minute.
