- Abstract
- Continuous gas lift is a high value optimization proposition, where high-pressure gas is injected at various depths, into oil production well to lightened the fluid column and so improve production and recovery. Gas lift optimization models as a surrogate for optimization planning, are usually nonconvex and even nonsmooth. Moreover, in many situations the objective and/or constraint functions in these problems are not known analytically. Most of traditional methods of optimization cannot be applied to solve such problems. Derivative free methods seem to be better choice for solving such problems. In this paper, we compare two different derivative free methods, our variant of the discrete gradient method and the generalized descent method for solving nonlinear gas lift optimization problems. We consider two different gas lift optimization problems. The objective functions in these problems are separable, nonsmooth and nonconvex. Although both algorithms produce satisfactory results, however the discrete gradient method better deals with noisy data and produces better results.; C1
