ODSI focused on the use of the Well Analyzer Automated Real-Time Surveillance (ARTS) for surveillance of a gas injector well in Offshore Australia. Key features included automated rate calculations, PVT adjustments, pressure transient interpretation, and monitoring of recoverable hydrocarbon volumes. The system enabled real-time performance optimization and included capabilities for identifying issues like wax hydrates, asphaltenes, and corrosion. The results from the surveillance of the gas injector highlighted the accuracy and effectiveness of the ARTS program in managing well and reservoir performance.
