Benefits of a HYSYS-based Production Facilities Surveillance System
Case Study: HYSYS-based Production Facilities Surveillance System for Pioneer Natural Resources
Process Ecology, an engineering consulting company, designed an HYSYS-based Production Facilities Surveillance System for Pioneer Natural Resources to monitor the performance of equipment and optimize the production rates and deliverability of contracts. The system helps operators understand the asset behavior and make better operational decisions by providing real-time monitoring, calculation, and estimation of production based on system conditions.
In a case study of Pioneer Resources' Oooguruk production facilities, the system was modeled in dynamic mode with 15 wells operating in free-flowing, ESP, or shut-in modes and three-phase flow (oil, water, gas) through sub-sea transportation pipelines. The key process elements included three phases (oil, water, gas) with compositional HYSYS oil characterization, different oil characteristics for each well, and ESP operation modeled using a multistage pump with manufacturer pump curve.
The HYSYS dynamic model was calibrated and verified against field data, and the model was combined with an online and real-time application to import field data into the model and record various production parameters calculated by HYSYS. The recorded information included each well oil, water, and gas production, temperature and pressure profiles, etc.
The HYSYS-based Production Facilities Surveillance System provides several benefits, including real-time calculation of well flow rates, diagnostics for wells that are not behaving according to the model, and what-if scenarios for pipeline flow regime and proration/shut-ins. The system also helps on-shore operators anticipate changes from island events.
Overall, the HYSYS-based Production Facilities Surveillance System designed by Process Ecology helps Pioneer Natural Resources optimize its production rates and deliverability of contracts by providing real-time monitoring and analysis of its production facilities.
