Summary: | Pressure cycle independent indexer devices and methods include an indexing logic having a trigger sequence path defining a pressure event (e.g., one or more pressure events) between a starting slot and an actuation slot and each pressure event being located between a sequence transition point from an incoming sequence leg into an outgoing sequence leg of the trigger sequence path and a return transition point from the trigger sequence path into a return path. The indexing logic may permit cycling hydraulic pressures in a well without inadvertently cycling through the trigger sequence path. |
