Well Production Casing Brady No. 5 Well, Geothermal Food Processors, Inc., Fernley, Nevada. Falure Analysis Report

摘要

Failure of the casing of the Brady No. 5 resulted from severe external corrosion. The well is located in a mineral flat and it is proposed that during wet periods the exterior of the casing was exposed to aerated saturated chloride and/or sulfate salt solutions. These solutions appear to have completely destroyed the surface conductor and upper string casing and associated cements. The production casing then corroded until mechanical failure occurred.
