Built on large models, this hybrid intelligent agent integrates real-time wellsite data acquisition and transmission systems, geological and engineering domain models, and a while-drilling decision knowledge graph to assist RTOC remote experts in daily operations. The system continuously monitors drilling parameters and equipment status across multiple wells, intelligently analyzes operational conditions, and delivers optimization recommendations, effectively mitigating expert fatigue and attention dispersion while improving analytical accuracy and efficiency. It supports the automated generation of daily reports, operational efficiency statistics, and various reports, significantly reducing manual workload. An embedded knowledge graph consolidates expert knowledge and industry standards to support the training of new personnel, substantially lowering operational risks and costs, and accelerating the transformation of RTOCs toward intelligent and high-efficiency operations. Dedicated intelligent agents can be custom-developed and deployed according to the customer’s data environment.
