Ultra-high-rate gas separator enables efficient offshore well clean-up operations

Page last modified
September 2 2025

The MegaFlow™ ultra-high-rate separator single train package is an advanced well testing solution developed by Expro for offshore gas reservoirs. It is designed to handle flow rates up to 175 MMscf/d, significantly higher than standard separators. The system integrates industry-leading process safety best practices and enables efficient well clean-up operations.

Key features of the MegaFlow™ package include:

1. Single train design: This reduces operational complexity, risks, and crew requirements compared to conventional two-separator solutions.

2. High-efficiency separation: It incorporates a Multi Tube High Efficiency Heat Exchanger to ensure complete and efficient separation of different phases, even with high Condensate Gas Ratios (CGR).

3. Integrated safety systems: The package includes an API 17G compliant, high temperature/debris tolerant Expro Landing String Assembly (ELSA) subsea safety system.

4. Sampling and analysis capabilities: It features Expro's unique sampling and analysis package for mercury characterization.

The MegaFlow™ system offers significant advantages over standard separators, including a smaller footprint, reduced rig time, and lower overall costs. Its enhanced throughput capabilities shorten well clean-up time, saving valuable rig time and reducing greenhouse gas emissions. Additionally, the increased radius of investigation improves reservoir characterization, leading to optimized long-term production and management.
