Analysis of Optimal Control Strategies for Efficient Operation of a Produced Water Reinjection Facility for Mature Fields

Abstract Produced water management policies in oil and gas industry have been moving towards zero emission, no ocean discharge waste-to-value conversion. reinjection plays a key role achieving these goals for mature fields as it derives value from produced is able to maintain environmental integrity. A central element this, optimal operation of pumping. Hydraulic efficiency specific energy are generally the chosen indices used evaluate operational pumping systems. In this work, we investigate optimization strategies based on natural objective function candidates system: (i) at best point; (ii) minimization total shaft input power; (iii) maximization overall pump hydraulic efficiency; (iv) (v) delivered energy. addition, discuss implication different solutions over control structure selection.
