Title: DRILLING FORMATION TESTER, APPARATUS AND METHODS OF TESTING AND MONITORING STATUS OF TESTER
Abstract:
Integrated drilling and evaluation systems and methods for drilling, logging and testing wells are provided. The drilling and evaluation systems are basically comprised of a drill string (18), a drill bit (30) carried on a lower end of the drill string (18) for drilling a well bore, logging while drilling apparatus (28) included in the drill string (18) for identifying subsurface zones or formations of interest, packer means (32) carried on the drill string above the drill bit for sealing a zone or formation of interest below the packer means (32), a fluid testing means (26) included in the drill string (18) for controlling the flow of well fluid from the zone or formation of interest into the drill string (18), a function status monitor included in the drill string (18) to evaluate the capacity of the various test instruments to function, and a function timer (31) included in the drill string (18) to automatically sequence the steps of the various test procedures. The drilling and evaluation systems and methods for using the systems allow one or more subsurface zones or formations of interest in a well to be drilled, logged and tested without the necessity of removing the drill string (18) from the well.
