摘要
A new sub-surface zone 406 of an existing production well (10) is perforated by shutting down production of the well through a production tubing bore (32) and running a coiled tubing test string (400) down into the production tubing string (26). The coiled tubing test string includes a perforating gun (402) and optionally a test packer (54). The gun (402) is fired adjacent the new zone (406) to make perforations (408) therein, and the coiled tubing string (400) is removed and production resumed.
