Integrated production optimization through model-based decision support and advanced optimization techniques

Résumé

The Production Optimization is one of the most complex and multi-disciplinary task in the oil&gas industry from an operational point of view: it involves the surface asset during all its production life and requires a continuous improvement process. In the gathering facilities and process plant engineering design, the optimization is driven by inputs that are subjected, during the asset life, to changes; this fact, coupled to improvements and modifications in surface facilities, creates the necessity to manage and optimize production scenarios with a more frequent time-frame. Technology improvements have enabled a widespread use of integrated simulation models for a better asset management to be fully combined with measured field data. In this paper we present a dedicated workflow for surface facilities – gathering system and process plant – production enhancement and management coupled with an advanced optimization technique based on a powerful algorithm. The main feature of this algorithm – and consequently of the proposed workflow – is the ability to control many variables simultaneously according to the system constraints even with complex, conflicting and non-direct interconnections between them and the objective to be reached. It has been proven that this algorithm has a robust practice that detects the global optimum of the feasible area avoiding a premature stop in a local optimum region, a situation quite common in highly-constrained and non-linear optimization problems in oil&gas industry. The technical contributions of the work are the abilities to support operations in: definition of field potential, production optimization and de-bottlenecking activities. In the paper a case study that tackles a more complex situation presented in [1], is reported; the proposed workflow’s results are compared with another integrated optimization software available from other software-house, showing an improved ability to detect global optimum combining well management to the plant capabilitie
