Design of Digital Twin for Offshore Gas Condensate Field
September 2024
One of the major global gas producer has successfully partnered with us to deliver an advanced project for the design of a digital twin for an offshore gas condensate field with subsea production systems.
The project scope included a pre-project survey, analysis of best practices, elaboration of functional and technical requirements, engineering and conceptual design, selection of the most suitable software-hardware architecture, and a feasibility study for implementing a proactive management system for the offshore field.
The organizational scope covered the subsea production complex and the onshore gas processing plant with a condensate stabilizer. The produced fluids include dry gas, stable gas condensate and natural gas liquids.
Digital twin functionality
Keeping the equipment and materials register for maintenance purposes.
Planning the integrated maintenance schedule across all departments, including inventory planning.
Monitoring operational modes and proactive responses to prevent complications in the subsea production complex, including wells and the gathering system.
Continuous optimization of well performance at the onshore processing plant and condensate stabilizer to maximize the recovery of liquid hydrocarbons.
Key project objectives
Integration of existing systems and data acquisition.
Incorporation of the lifecycle management system for equipment.
Development of the digital integrated model using both physical (first-principle) models and neural network models.
Configuration of executive dashboards for KPI monitoring, data entry and performance tracking.
Expected outcomes for the customer
1.2% annual increase in production of stable gas condensate.
3.5% reduction in equipment repair costs.
5% reduction in material costs due to decreased consumption of MEG and methanol.
