Abstract
This report describes a minitest consisting of a central injection production well surrounded by at least two observation wells designed to detect the arrival of injected fluid, leached minerals, and nonideal flow. The goals of the test are to determine the susceptability of the host formation for uranium leaching, to establish important kinetic parameters so that the results of the minitest can be used to correctly scale the process, and to identify those factors that may render site restoration difficult. The report considers nonidealities such as reservoir permeability hetero- geneities, nonuniform mineral distribution, and minerals other than uranium that may react with the leach solution. To circumvent these difficulties, methods of interpretation were proposed and tested by analysis of realistic data generated by a computer simulator. Clear- cut methods of interpretation were not found in the more complex cases, but in every case the design of an optimum test was considered and recommendations made.
