Abstract

This system and Method serve as both a raw data logger for well operation analysis and a well event logger for well performance analysis. An improved methodology of remote event and process variable logging and data retention designed specifically to address the needs of intermittently flowing gas wells is useful for eliminating gas slippage associated with intermittent or erratic gas flow conditions, eliminating measurement errors, and lowering operating costs. The well data can be scanned in seconds for its current flow situation, and as a set of specific conditions are met, a built-in control program reacts to those conditions by shutting down the well until certain pressure criteria are met to allow the well to flow again. To maintain measurement integrity, precise event logging of the valve positions to indicate the actual flowing period are included in the flow integration. There are auto-calibration and reintegration features in the system methodology for eliminating slippage gas and eliminating settling disputes between the producer and the pipeline operator. Graphical presentation of event logs and process variable data allows the user to quickly and effectively diagnose and correct gas well problem. The same graphical presentation provides visual inspection and analysis to optimize gas well production.
