ABSTRACT:
A method and system for drillstem testing multiple zones in a well with a single testing trip into the well. A multiple zone tester is landed in the lower completion to form separate controllable flow paths from each of the zones. The multiple zone testing system facilitates testing each zone singularly and performing commingled tests without pulling out of the well.
