The NexStep Dissolvable Toe initiator (NexStep DTI) provides a reliable secondary barrier. NexStep technology is a cost-effective solution for testing casing, initiating the fracturing process, and increasing production potential from the first stage. Injection is established through dissolvable port plugs and can be set up to mimic any perforation design. With a slim OD and full-bore ID, NexStep subs are run just like casing. NexStep DTIs open at every port, preventing plug-offs often associated with standard toe sleeves.

Compatible with most cement slurries. Customized salinity testing is highly recommended before deployment.
