Production Asset Operation Optimization: Current Situation and Potential Solution
OBJECTIVE:
Identifying optimization solutions for equipment operation modes in the production and preparation chain:
• Production allocation across wells
• Selection of fractionation column operating mode
• Optimization of low-temperature separation processes
• Compressor equipment efficiency
• Production allocation across wells
• Selection of fractionation column operating mode
• Optimization of low-temperature separation processes
• Compressor equipment efficiency
CHALLENGES:
• Using models for decision-making in "manual mode" requires significant time to generate optimization variants for control
• Specialized personnel are needed to operate the solution and derive operational mode variants for the facility
SOLUTION:
• Real-time integrated digital twin automatically calculates product flow parameters through equipment
• Virtual sensor system, based on digital twins, provides flow parameters at any asset section (temperature, pressure, component composition)
• Optimization algorithms automatically generate optimal equipment operation variants to increase target product output
• Specialized personnel are needed to operate the solution and derive operational mode variants for the facility
