This paper considers the upstream oil and gas domain, or more precisely the daily production optimization problem in which production engineers aim to utilize the production systems as efficiently as possible by for instance maximizing the revenue stream. This is done by adjusting control inputs like choke valves, artificial lift parameters and routing of well streams. It is well known that the daily production optimization problem is well suited for mathematical optimization. The contribution of this paper is a discussion on appropriate formulations, in particular the use of static models vs. dynamic models. We argue that many important problems can indeed be solved by repetitive use of static models while some problems, in particular related to shale gas systems, require dynamic models to capture key process characteristics. The reason for this is how reservoir dynamics interacts with the dynamics of the production system.

本文考虑了上游油气领域，或更确切地说是日常生产优化问题，生产工程师旨在通过例如最大化收益流来尽可能高效地利用生产系统。这可以通过调节控制输入（例如节流阀，人工举升参数和井流路线）来完成。众所周知，日常生产优化问题非常适合数学优化。本文的贡献是对适当公式的讨论，特别是静态模型与动态模型的使用。我们认为，重复使用静态模型确实可以解决许多重要问题，而某些问题（尤其是与页岩气系统有关的问题）则需要动态模型来捕获关键过程特征。
