         18 . A method of completing a well comprising of the following steps: cementing a casing string in place; perforating a first zone at a first depth; injecting stimulation fluid from the wellbore into the formation through the perforations in the first zone; producing fluid from the first zone of the formation; running a packer mounted valve in a closed position above the perforations of the first zone, such valve including a timed delayed programmable actuator; setting the packer and valve within the casing to pressure isolate the wellbore above the valve from the formation in the first zone; perforating a second zone at a second depth that is shallower than the valve placement depth; injecting stimulation fluid from the wellbore into the formation through the perforations in the second zone; producing fluid from the second zone of the formation; allowing the valve to automatically open upon the expiration of the time programmed in the valve actuator to allow both zones to communicate. 
     
     
         19 . A method of completing a well comprising of the following steps: cementing a casing string in place; perforating a first zone at a first depth; producing fluid from the first zone of the formation; running a first packer mounted valve in a closed position above the perforations of the first zone, such valve including an actuator; setting the packer and valve within the casing to isolate the wellbore above the valve from the formation in the first zone; perforating a second zone at a second depth that is shallower than the valve placement depth; and, producing fluid from the second zone of the formation. 
     
     
         20 . The method of  claim 19 , further comprising the steps of running a second packer mounted valve in a closed position above the perforations of the second zone, such valve including an actuator; setting the packer and valve within the casing to isolate the wellbore above the valve from the formation in the second zone. 
     
     
         21 . The method of  claim 20 , further comprising the steps of perforating a third zone at a second depth that is shallower than the valve placement depth; producing fluid from the third zone of the formation. 
     
     
         22 . The method of  claim 19 , further comprising the step of injecting stimulation fluid from the wellbore into the formation through the perforations. 
     
     
         23 . The method of  claim 18 , wherein said casing string further comprises:
 a rotating sleeve and wherein said casing string further comprises at least a first mandrel port extending from an exterior surface of said casing string to an interior surface of said casing string; and a cement flowpath defined by a passage connecting at least a first opening and a second opening on the exterior surface of said casing string which are positioned axially displaced from and at opposite sides of said first mandrel port, and wherein said rotating sleeve is rotatably positioned on said casing string, said rotating sleeve comprising at least one sleeve port, wherein said rotating sleeve rotates between at least a first position wherein said at least one sleeve port does not align with said at least one mandrel port and a second position wherein said at least one sleeve port is at least partially aligned with said at least one mandrel port.   
     
     
         24 . The method of  claim 19 , wherein said casing string further comprises:
 a rotating sleeve and wherein said casing string further comprises at least a first mandrel port extending from an exterior surface of said casing string to an interior surface of said casing string; and a cement flowpath defined by a passage connecting at least a first opening and a second opening on the exterior surface of said casing string which are positioned axially displaced from and at opposite sides of said first mandrel port, and wherein said rotating sleeve is rotatably positioned on said casing string, said rotating sleeve comprising at least one sleeve port, wherein said rotating sleeve rotates between at least a first position wherein said at least one sleeve port does not align with said at least one mandrel port and a second position wherein said at least one sleeve port is at least partially aligned with said at least one mandrel port.   
     
     
         25 . The method of  claim 18 , wherein the packer mounted valve is a blapper valve. 
     
     
         26 . The method of  claim 19 , wherein the packer mounted valve is a blapper valve.
