Optimized Single-Trip Multi-Zone (OSTMZ™) sand control system reduces surface activities, rig time, and risk during multi-zone sand control operations
Talk to an expertThe OSTMZ™ sand control system is designed to help operators manage multi-zone completions in a single trip. This solution combines frac-pack functions into one streamlined approach, reducing operational complexity and supporting better reservoir access. The system optimizes completion operations commonly applied in high-rate wells and regions such as the Gulf of America, Southeast Asia, Mexico, and West Africa.
Multi-zone completions often require multiple trips and complicated tool handling, which can increase costs and operational risk. The OSTMZ system addresses those challenges by delivering single-trip frac-pack and gravel pack operations. The design helps reduce rig time and simplifies surface activities beyond what has been achieved with previous single-trip multi-zone systems, which can lower personnel requirements in restricted areas.
Engineered for operational simplicity, this unique design features a bidirectional flow path and frac sleeves, which create a frac-pack system that combines the functions of the sand control completion and service tool into a single system. This allows all zones to be treated without repositioning the deployment tool or retesting surface equipment.
Zones not being treated are isolated from the wellbore, which helps prevent bypassed reserves. Balls can be circulated onto their seats and reversed out, and no inner string is required, so the full system ID is available during production.
The OSTMZ sand control system combines simplicity with reliability using proven components. Its modular screen design allows for custom zone lengths. Operators can perform frac and pack operations with reverse-out capability in each zone. These features help streamline completions and improve operational efficiency.
Operators often apply this solution in wells that require multi-zone frac-pack or gravel pack operations. It is designed for operators who want to reduce completion complexity and improve productivity in challenging environments.
Compatibility with standard packers and frac sleeves makes integration straightforward. Built for flexibility, it fits easily into existing completion strategies without major redesigns.
