Abstract:
1. A running tool for delivery and sequential expansion into an existing tubular of a hanger mounted to a tubular string followed by expansion of a sealing assembly mounted to the tubular string, comprising: a mandrel having an upper end and a passage therethrough; an anchor assembly on said mandrel selectively engageable to the tubular string; a stroker assembly on said mandrel to selectively drive a swage assembly into the tubular string while said anchor assembly selectively grips said tubular string using pressure in said passage; said passage selectively closed at a first and at a second location, said anchor assembly in fluid communication with said passage on opposed sides of said first location with at least one upper port and at least one lower port, said second location is further from said upper end of said mandrel than said first location; said anchor assembly actuated once with pressure in said passage delivered to said upper port from said upper end of said mandrel with said passage closed at said first location; and said anchor assembly actuated another time with pressure in said passage delivered to said upper port from said upper end of said mandrel with said passage closed at a second location and open at said first location and with said lower port selectively closed, said lower port subsequently opened for removal of the running tool from the tubular string with said upper and lower ports open.
