Oil and Gas Asset Digitization



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

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

POTENTIAL BUSINESS BENEFITS:
• Forecasting profit maximization for the asset’s target product
• Increased output of target commercial products (LPG, stable condensate)
• Energy savings
• Reduced methanol usage costs
• Improved commercial product quality (compliance with standards)

Implemented Business Projects:

Digital Twin of Well Stock and Gas Collection Network

Results:

• Digital twin enabled assessment of well park operation mode changes upon commissioning a new well (well was under drilling during twin creation).

• Model allowed evaluation of flow rate and component composition changes for each well and at GPP inlet
