Oil & Gas Upstream

Sensa fiber optic monitoring systems capture reliable, accurate and real-time downhole temperature profiles.

By monitoring the thermal profiles production and reservoir, engineers can identify the time, location and most likely reason for changes in the mass flow, allowing more effective drainage of the reservoir.

Wellbore temperature is continuously collected and transmitted to the surface using permanently installed fiber optic technology. At the surface, the data can be transmitted to multiple remote locations using satellite, Internet and cable communications.

Our solution provides significant production management advantages for your well or an entire field. Sensa empowers engineering and management personnel with the information to maximize reservoir performance, optimize well production and reduce operating costs.

Applications

• Permanent real time surveillance across the reservoir in land, platform and subsea wells
• Identification of zonal inflow from multiple reservoir layers
• Modeling of distributed reservoir pressure decline in individual layers
• Assist in identifying time and position of water or gas breakthrough
• Confirmation of gas lift valve operation
• Identify completion conformance issues such as flow behind casing, tubing and packers leaks
• Monitoring of pipelines and flowlines to detect hydrate location

Benefits

• Improved recovery through better reservoir modeling and field management
• Location and design of infill wells can be improved through better understanding of reservoir models and well performance
• Reservoir pressure support and sweep efficiency are optimized by modeling individual layer pressures
• Well clean-ups can be monitored over a period of months identifying trends more effectively than intervention based monitoring equipment
• Well designs can be measured against expected performance and improved over the field development
• Addresses the lack of reservoir monitoring data in subsea wells or in fields where production logging is difficult

Features

• High-resolution measurement with advanced signal processing
• Self-calibrating temperature measurement with redundancy
• Onshore real time monitoring of performance across the reservoir
• Intelligent Well Interface Standard (IWIS) compliant subsea module
• Utilises design and deployment experience from Schlumberger permanent pressure gauge business
