Flowing water samples and bottom-hole water samples were taken for chemical analyses during a recent test sponsored by the Energy Research and Development Administration. The Edna Delcambre et al 1, Tigre Lagoon field, Vermilion Parish, Louisiana, was perforated at two levels between 12,500 and 13,000 ft (3,625 and 4,000 m) and the geopressured-geothermal fluid was allowed to flow through a test barge. Chemical analyses were conducted on site and in other laboratories. Trends in pH, bicarbonate, metals, etc., and typical values for other ions were compared among and within sands as a function of time. Analyses for radon gas and other radioactive materials were made. In-line measurements for pH suggest that laboratory measurements do not give the correct value in geopressu ed fluids where the gas and liquid are not in equilibrium.
