Products Description
The CAN2000 Series Downhole Memory Gauge is a versatile, high-accuracy downhole pressure and temperature recording system designed for demanding oil and gas well environments. Featuring reliable long-term data storage and exceptional measurement stability, it provides precise downhole pressure and temperature data for reservoir analysis, production optimization, and well performance evaluation.
Compatible with DST tools and other downhole testing equipment, the CAN2000 can be utilized for conventional well testing, perforation-testing operations, pressure buildup and drawdown analysis, injection well monitoring, and various production surveillance applications. It can also operate independently, offering a flexible and cost-effective solution for a broad range of downhole measurement requirements.
Product Applications
- Pressure buildup and pressure drawdown testing
- Single-rate and multi-rate production testing
- Logging-perforating integrated operations
- Reservoir interference and pulse testing
- Reservoir boundary evaluation
- Static and flowing pressure measurements
- Pressure gradient surveys
- Injection well monitoring
- Post-acidizing and post-fracturing performance evaluation
