A retrievable bridge plug and packer apparatus. The tool includes a packer settable by right-hand rotation and vertical manipulation of the tool string and a bridge plug also settable by right-hand rotation and vertical manipula- tion of the tool string. A disabling tool is provided to disable the packer during setting of the bridge plug so that the packer is not prematurely set. After setting of the bridge plug below the formation, the packer and disabling tool may be disengaged from the bridge plug. At this point, the disabling tool is disengaged so that the packer may be set above the formation. The packer is unset by pulling on the tool string, and the packer and disabling tool may be reconnected to the bridge plug. Again lifting on the tool string unsets the bridge plug so that the apparatus may be retrieved or reused. A method of treating a well formation is also disclosed.
