1. A method comprising:
- running an assembly having plural valves into a wellbore having plural zones, each of the valves actuatable by dropping a valve-actuating object into the corresponding valve;
successively actuating, in a predetermined sequence, the valves to an open state; and
successively testing the zones after actuating corresponding valves to the open state.

Abstract
An assembly having plural valves is run into a wellbore having plural zones, where each of the valves is actuatable by dropping a valve-actuating object into the corresponding valve. The valves are successively actuating, in a predetermined sequence, to an open state. The zones are successively tested after actuating corresponding valves to the open state.

24. A system for use in a wellbore, comprising:
-
a plurality of valves, each valve having a first state and a second state;
a plurality of valve-actuating objects to be dropped into the wellbore to successively open corresponding valves, each valve when in the first state allowing valve-actuating objects to pass through, and each valve when in the second state catching a corresponding valve-actuating object; and
a testing tool coupled to the plurality of valves to test corresponding zones of the wellbore proximal corresponding valves. - View Dependent Claims (25, 26, 27, 28, 29, 30)
