Limited-Entry Capable, Pressure Testable Toe Initiation Sub
Mimick the Uphole Cluster Design for Stage 1
Fully Treatable Stage 1
Built-in Redundant Contingencies
Run multiple Crypto™ Subs in the toe of the well with the same cluster spacing as your uphole plug and perf design. All Crypto™ Subs and all ports will be open and can accept fluid.
Recoup previously lost toe reserves and toe production.
When running multiple Crypto™ Subs in a limited-entry toe design all ports in all Crypto™ Subs will open even after other ports have opened and are accepting fluid.
Pump Stage 1 with the same rate, tonnage and proppant concentration as all the uphole stages.
All six ports within one Crypto™ sub will open after the first port is opened and the reservoir is accepting fluid.
Crypto™ has minimal moving parts, no shear pins, no atmospheric chambers, no burst discs, no sliding sleeves, no cavities, and can be pressure testable up to 14 days from the production string cement job being bumped.
