摘要： A system for operating a downhole tool includes a tag carrier; a RFID tag coupled with the tag carrier; and a control sub having a bore extending therethrough, the control sub comprising: an antenna located adjacent to the bore; and a stop for catching the tag carrier, wherein: the radio frequency identification tag is coupled with the tag carrier in relation to the stop and the antenna such that the radio frequency identification tag is aligned with the antenna when the tag carrier is caught in the stop, and the stop is operable to allow passage of the tag carrier through the stop after the tag carrier is caught by the stop.

摘要： A method of using a liner assembly comprises inserting the liner assembly into a wellbore, the liner assembly having an annular packer and a port collar. The method further comprises closing fluid flow through a lower end of the liner assembly, actuating the annular packer into engagement with the wellbore, and actuating the port collar into an open position to open fluid communication between an interior of the liner assembly and the wellbore. The method further comprises pumping cement into the wellbore through the port collar at a location above the annular packer and actuating the port collar into a closed position to close fluid communication between the interior of the liner assembly and the wellbore.
