Delayed Open Toe Sleeve
Time-Controlled Toe Initiation Tool
Product Overview
The Delayed Open Toe Sleeve delivers precise, delayed actuation for controlled stage-one initiation without explosives. Engineered for modern plug-and-perf and plug-and-frac programs, the tool enables operators to introduce deliberate timing into the toe-prep sequence to optimize operations and reduce intervention.
Key Features
- Fixed 30-minute or 1-hour actuation delay
- Sealed internal fluid chamber ensures predictable timing
- Integrated pressure disc triggers clean, reliable opening
- Eliminates explosives and associated logistics
- Simple mechanical design compatible with most completions programs
Applications & Drilling Scenarios
- Wells requiring staged or staggered toe opening
- Completions needing controlled operational timing before frac initiation
- Extended displacement or pressure stabilization prior to stage one
- Non-explosive toe initiation programs
Advantages
- Engineered delay options reduce operational uncertainty
- No explosives – streamlined HS&E compliance and logistics
- Highly predictable timing through a sealed fluid chamber and disc system
- Low-complexity design ensures reliability in diverse well conditions
Compatibility
- Fully compatible with plug-and-perf and plug-and-frac systems
- Supports both hydraulic and hybrid stimulation strategies
- Suitable for use with standard completion strings and valves
