Abstract
A formation testing method can include deploying a drill string including a packer and a circulating tool into a well, setting the packer, thereby blocking fluid flow through an annulus, and opening the circulating tool, thereby permitting fluid communication between the annulus and an interior flow passage of the drill string. The opening step can include displacing a radio frequency identification tag into the circulating tool. A formation testing system can include a drill string with a drill bit, a circulating tool and a packer. The packer is configured to seal off an annulus, and the circulating tool is selectively operable to permit fluid communication between the annulus and an interior flow passage of the drill string in response to a radio frequency identification tag being deployed into the circulating tool.
