ABSTRACT:
The method and apparatus for treating multiple production zones includes a completion string having a plurality of sets of tools including a closing sleeve, indicator collar, and production screens with an isolation packer disposed between each adjacent set. An inner service tool is disposed within the outer completion string and includes an upper portion with a crossover tool and a lower portion with a closing sleeve shifter and a weight-down collet with the upper and lower portions being connected. The apparatus is assembled by assembling an initial length of the outer completion string which does not includes any of the closing sleeves or indicator collars. After the initial length is assembled, the lower portion of the service tool with the closing sleeve shifter and weight-down collet are assembled and inserted into the initial length of completion string. The remainder of the completion string is then assembled with all closing sleeves in the closed position. The upper portion of the service tool is then assembled and stabbed and connected into the lower portion. As multiple production zones are treated, the inner service tool is raised and then lowered opening a closing sleeve and setting weight on the indicator collar. A predetermined amount of weight is then maintained during the operation to ensure that the crossover tool is positioned adjacent the opened closing sleeve. The production zone then may be treated in the weight-down position.
