Corrosiondata were obtainedin a well in the Salton Sea GeothermalField. These data were obtainedfrom inspectionof steel tubin~removedfrom the 4200-footwell and from spedmene of variousalloys exposed at the bottom of the well. Analyseswere made of scale on the tubingsurfaceat five locationsof varyi~g depth. Corrosiondata were obtainedalso from specimensexposed in surfaceequipmenthandlingthe steam and high salinitybrine producedby the well.
