Abstract
An apparatus and operating method allows the completion of multiple production zones in a single wellbore with a single downhole trip. The work string descends with a coaxially combined completion string and service string. The completion string is set into a previously set basement packer. The completion string includes a series of production screens, transverse flow orifices, isolation packers and collet indicating couplings, all prepositioned along the completion string length relative to the basement packer set location. The production sleeves and transverse flow orifices are selectively closed by axially sliding sleeves. The service string includes a crossover flow tool, a SMART collet tool, sleeve shifting tools and sleeve closing tools. With all orifice and screen closure sleeves closed, the procedure proceeds from the lowermost production zone to open the closure sleeves respective to the flow orifice and screens dedicated to a respective production zone. As each zone is completed, the respective flow orifices and screens are closed and the next higher zone orifices and screens are opened.
