Patent ID: 7096976

Claim:
An integrated well drilling and evaluation system for drilling and logging a well and testing in an uncased well bore portion of the well, comprising: a drill string having an interior portion; a drill bit carried on a lower end of the drill string, for drilling the well bore, wherein the drill bit includes ports for communicating fluid between the interior portion of the drill string and the uncased well bore; a packer, carried on the drill string above the drill bit, having a set position for sealingly closing a well annulus between the drill string and the uncased well bore above a subsurface zone of interest and having an unset position such that the drill bit may be rotated to drill the well bore, the packer being selectively positionable between the set position and the unset position; a tester valve, inserted in the drill string, wherein the tester valve has an open position and a closed position for sealingly closing the interior portion of the drill string, the tester valve being selectively positionable between the open position and the closed position and is cooperatively operable with the packer to shut in the subsurface zone, and with the packer in the set position, the tester valve is operable to be selectively moved to the open position to allow well fluid from the subsurface zone to pass through die interior portion of the drill string to a surface location; monitoring means, inserted in the drill string, for monitoring a parameter of well fluid from the subsurface zone, wherein when the packer is in the set position and the tester valve is in the closed position, well fluid from the subsurface zone 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 from the well; an electronic control package that is cooperative operable with and controls the operation of a least the packer and the tester valve; a function timer that is cooperatively operable with die electronic control package to control the sequence of sampling for collecting well fluid from the subsurface zone after receiving an initiating signal from a surface location; and a functional status monitor, included in the drill string and separate from the function timer and the electronic control package, comprising at least one sensor for monitoring a functional status of at least one of the monitoring means, the packer, and the tester valve.
