Abstract
A downhole assembly includes a tool-orienting device including an operating unit that obtains downhole measurements and a pulse-generating device that transmits the downhole measurements to orient a downhole tool. A restrictor sub is coupled to the tool-orienting device and includes a nozzle that restricts fluid flow therethrough, and a circulating valve is coupled to the restrictor sub and includes a nozzle that restricts fluid flow therethrough. A liner running tool is coupled to the circulating valve to convey a liner and a pressure-activated tool into the wellbore. The pulse-generating device operates with a fluid at a first pressure and the restrictor sub is actuatable by increasing the first pressure to a second pressure. The circulating valve is actuated by the fluid at a third pressure and the pressure-activated tool is activated by increasing third pressure to a fourth pressure.
