Product Overview
The ZoneSelect™ Rupture Disc (RD) Toe Sleeve with Fike Discs is a critical component of multizone well completions, engineered to initiate formation access with rupture-disc actuation. Designed for both cemented and openhole applications, this toe sleeve enables efficient stimulation operations by providing a reliable, high-pressure-rated initial point of entry. It’s ideal for use in plug-and-perf systems or as part of the Weatherford ZoneSelect system, offering unmatched precision, durability, and operational safety.
Key Features, Benefits & Advantages
-
±4% Pressure Tolerance – Ensures accurate actuation pressure indication to improve operational confidence.
-
High Flow Area – Large ports optimize stimulation capacity, boosting production rates.
-
Ball Drop Compatibility – Upper sub accepts a dissolvable ball for casing pressure tests and plug replacement in extended reach wells.
-
Mill-Out Cost Savings – Eliminates the need to pump the first plug in plug-and-perf operations.
-
Permanent Lock-Open Mechanism – Prevents accidental closure post-actuation, ensuring sustained zone access and enhanced safety.
