Abstract
Since its introduction in Canada, the wire-line Formation Tester has proven to be valuable in evaluating prospective oil- and gas-bearing formations. In this paper, firstly, the procedures presently used in interpreting Formation Tester re- sults will be reviewed. Then, a method will be discussed for deter- mining formation permeability from Formation Tester recovery and log data. For both of these, illustrative field examples are given.
