An Automated System For Closed Chamber Drillstem Testing

Software and a manifolding system for automating closed-chamber drillstem tests have been developed. This paper describes the software, the manifolding and, briefly, the data acquisition system that provides the interface between them. In addition, it presents improved correlations for determining the maximum influx rates of gasfree and gas-saturated water. The typical test procedure is outlined in the paper and an actual example of a closed-chamber test illustrates the paper.
