Paper: Real-Time Ananlysis on a DrillStem Test Using Wireless Telemetry

The openhole drillstem test (DST) has changed little in the last 30 years; however, pressure-transient analysis recently has made significant advancements. Modern electromagnetic telemetry systems are the basis for an economical method of transmitting pressure and temperature readings in real time." Improvements in information technology now allow advanced on-site analysis. This paper provides an overview of an openhole test, describes the components used during real-time analysis, and discusses the case history for a real-time job in Andrews County, TX.
