A method and apparatus is used to test and/or treat individual production zones of a well in conjunction with a conventional coiled tubing unit. This method and apparatus allows testing and treatment of a well with production tubing in place. The return flowpath for formation fluids and/or treatment fluids is through the annulus between the coiled tubing and the production tubing. The preferred embodiment uses straddle packers, but alternative embodiments may use only a single inflatable packer.
