摘要
A drilling optimization method including perturbing one or more drilling control parameters with a periodic or a stochastic signal during a drilling process, estimating at least one drilling performance measure to optimize the drilling process based on the perturbed one or more drilling control parameters, perturbing the at least one drilling performance measure with a periodic or a stochastic perturbation source through demodulation, determine a next best estimate of the one or more drilling control parameters to optimize the at least one drilling performance measure, perturbing the next best estimate by a periodic or a stochastic perturbation source through modulation, and feeding the perturbation next best estimates of the one or more drilling control parameters back to the drilling process.
