Comprehensive Evaluation Method for Gas Field Surface Engineering Production Ensures Safety

Strategic Insights

— 2 min read

Research conducted by PetroChina Southwest Oil and Gas Field Company has identified the importance of a comprehensive evaluation method in ensuring the safe and stable operation of control system designs in gas field surface engineering production. The study found that over-reliance on standardized design approaches can compromise system flexibility and neglect individualized cost-effectiveness considerations. A proposed integrated semi-quantitative and quantitative evaluation method was designed to assess the effectiveness of station automatic control systems, taking into account the distinct process characteristics of various gas field stations.
