Inflatable packer systems can be configured in a variety of ways to allow production testing to determine fluid influx type and rate at various depths. When used in conjunction with standard well testing tools, the systems can also help determine formation damage. Configurations include straddle assemblies, bridge plugs, and production packers, and they can be deployed on coiled tubing or the work string. Inflatable packers can be used in open hole or cased hole completions, and in vertical, deviated, horizontal, or multi-lateral wells.
