Online CGR/GOR measurements

Online determination of Gas-to-Oil Ratio (GOR) and Condensate-to-Gas Ratio (CGR) using tracer dilution techniques offers a highly effective and efficient solution for continuous monitoring of hydrocarbon flow in production systems. This method uses a tracer injection technique, where a known amount of tracer is injected into the flow stream, and its concentration is measured downstream. By analyzing the dilution of the tracer in the flowing fluid, the GOR and CGR can be accurately determined in real-time, without requiring production deferment or the need for complex, traditional separation systems.

Key benefits include:

• Continuous Monitoring: Provides real-time GOR and CGR data, allowing operators to track reservoir performance and optimize production without interrupting operations.
• No Need for Traditional Separators: Eliminates the need for bulky separators or multiphase meters, reducing equipment requirements and space on platforms or at wellheads.
• Cost-Effective: Reduces operational costs by providing a portable, low-cost alternative to conventional methods that require high CAPEX and OPEX.
• Accurate and Reliable: Delivers precise measurements based on the dilution of the tracer, which is less dependent on the fluid characteristics and avoids the complexities of calibration required by traditional meters.
• Environmental Benefits: Reduces the need for flaring, methane emissions, and logistics associated with separator-based testing, supporting sustainability goals.
• High Flexibility: Can be applied to a variety of gas and condensate production systems, including both onshore and offshore fields, as well as subsea installations.

Overall, using tracer dilution techniques for GOR and CGR measurement enhances the efficiency and accuracy of production monitoring, while minimizing environmental impact and operational costs.
