Abstract
An integrated drilling and evaluation system includes a drill string having an interior portion and a drill bit, carried on a lower end, that includes ports for communicating fluid between the interior portion of the drill string and an uncased well bore. A packer, carried above the drill bit, is operable for sealingly closing a well annulus. A tester valve inserted in the drill string is operable for sealingly closing the drill string. The packer and tester valve are cooperatively operable for isolating a subsurface zone of interest. The system includes monitoring means inserted in the drill string for monitoring a parameter of well fluid from the subsurface zone. Once the subsurface zone is isolated, well fluid is communicated into the interior portion of the drill string through the ports of the drill bit, received by the monitoring means, and tested without removing the drill string form the well.
