“…The problem at hand is that of short-term planning of the operations in an offshore oil platform, in the scale from hours to days, according to the multilevel control hierarchy for oil production systems [1]. Recently, [7] advanced the technology for static optimization of offshore oil platforms by introducing features that are key in practice, such as the modeling of flow assurance constraints and dual completion (GLC and ESP), which yields optimal settings for the control variables to maximize oil production. However, that formulation does not consider the time dimension, which becomes relevant even for static models when operating conditions cannot be changed at once.…”

“…This choice of scope is made to simplify the research and presentation of the model in a more succinct manner. It is possible to combine the methodology for operations sequence optimization with a more general scenario that considers multiple platforms, wells with manifolds, naturally flowing wells, flow assurance constraints, and other forms of artificial lifting such as the use of an electrical submersible pump (ESP) [7].…”

“…Based on an extensive comparison between MINLP and MILP formulation for STPO, [6] proposed hybrid twostage optimization strategy for maximizing the oil production subject system and environmental constraints. [7] developed a generalized formulation for STPO to account complex production networks, well with dual completion that can operate with gas-lift injection and ESP, and flow assurance constraints to avoid hydrate formation.…”

Short-term production optimization of oil assets concerns routing decisions and equipment control settings that induce optimal steady-state operations. Typically, the decisions are made on the scale of hours to days with the aim of maximizing short-term economic and oil gains. Still an evolving field, this paper contributes by presenting a model and solution strategy for sequencing operations over time to drive the system towards an optimal state, while accounting for constraints that ensure smooth transitions until settling at the terminal steady-state. The constraints include the maximum number of wells that undergo a change in the control settings, maximum number and variation on the input signals for each well, and maximum number of changes in each time period, among others. Additionally, the proposed strategy can optimize the rate of injection of demulsifiers into wells considering the limits and impacts on fluid processing capacity. The paper reports simulated results for a real-world offshore production platform, demonstrating the effectiveness of the optimization strategy to cope with the failure and recovery of compression capacity, and manage the injection of demulsifiers.

“…As a result, the paper considers an urgent task to be optimizing the power consumption of the ESP and the efficiency of its operation. The main methods for optimizing the operation of the ESP are the correct selection of the pump by using the methods of nodal analysis, the introduction of new technologies and equipment, the optimization of the ESP's operation mode, the introduction of control systems, and the automation of the production process and the fight against complications [6][7][8].…”

Most of the operating oil fields are in the late stages of development, in which special attention is paid to the oil production energy efficiency. In accordance with the trend toward the digitalization of technical processes, intelligent control stations for production wells are currently being developed, one of the main tasks of which is to maintain the equipment operation in an optimal mode. This work aims to develop a methodology for selecting an energy-efficient well operation mode by choosing the methods for controlling an electrical submersible pump. To solve this problem, a mathematical apparatus for calculating power consumption is presented, which considers the well pressure curve, while taking into account its degradation when pumping reservoir fluids, the fluids’ properties, the supply of demulsifier, and the equipment’s operating parameters. Based on the simulation results, it is revealed that the optimal method for controlling electrical submersible pump installations is a combination of frequency control and choke control. The reduction in specific power consumption with the combined control relative to the use of separate control types is up to 7.30%, and in the case of additional use of a demulsifier, it is up to 12.01%. The developed algorithms can be implemented based on programmable logic controllers of intelligent control stations.
