Blapper valve tools and related methods

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.

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.
