Completion, method of completing a well, and a one trip completion arrangement

Abstract

A method of completing a well includes, positioning at least one valve within a tubular, closing the at least one valve, pressuring up against the closed at least one valve in a first direction, actuating a tool or treating a formation, opening the at least one valve without intervention, and flowing fluid past the at least one valve in a second direction.

What is claimed is: 
     
         1 . A completion comprising:
 a tubular; and   at least one valve in operable communication with the tubular configured to initially provide no restriction to flow or intervention being subsequently closable to fluid in a first direction sufficiently to allow actuation of a tool or treatment of a formation while allowing fluid therepast in a second direction, the at least one valve being openable to flow therepast in the first direction without intervention after a period of time.   
     
     
         2 . The completion of  claim 1 , wherein the at least one valve includes a flapper. 
     
     
         3 . The completion of  claim 1 , wherein a movable portion of the at least one valve that allows pressure to be built thereagainst while closed is dissolvable. 
     
     
         4 . The completion of  claim 3  wherein the movable portion of the at least one valve that allows pressure to be built thereagainst while closed is isolated from fluid within the tubular prior to the at least valve being closed. 
     
     
         5 . The completion of  claim 1 , wherein minimum radial dimensions of the at least one valve prior to actuation and subsequent reopening are no smaller than minimum radial dimensions of the tubular longitudinally beyond the at least one valve in either direction. 
     
     
         6 . The completion of  claim 1 , wherein the at least one valve is closable in response to a shifting tool moving therepast in the second direction. 
     
     
         7 . The completion of  claim 6 , wherein the at least one valve is a plurality of valves. 
     
     
         8 . The completion of  claim 7 , wherein the plurality of valves are sequentially closable in the second direction. 
     
     
         9 . The completion of  claim 7 , wherein the plurality of valves are configured to be reopened to flow in both directions without additional intervention after having been shifted to allow closure of the plurality of valves. 
     
     
         10 . A one trip completion arrangement, comprising:
 a plurality of valves positioned within a borehole each being configured to close to downhole flow once shifted for at least a duration of time and to allow uphole flow regardless of whether shifted; and   a multi-tool configured to separately shift each of the plurality of valves and repeatedly perforate a lining of the borehole to allow fracing through the perforated lining with pressure built against one or more of the shifted and closed valves, such that a plurality of separate zones can be fraced and the borehole open to production upon a single trip of the multi-tool.
