STAVANGER -- StatoilHydro has received consent to conduct a major modification of Troll C. The consent relates to installation and use of a new module on the facility.
The object of the modification is to facilitate production (from selected wells) against a lower separator pressure by using a test separator.
The modifications will result in:
• Increased recovery rate from wells with a high degree of water/low reservoir pressure
• Accelerated production from such wells
• Increased robustness in relation to reservoir instability.
The company will carry out construction of a new compressor module; loading, transport, and unloading of the new module; connection work and completion, and commissioning.
Most of the work will be carried out with the facility in normal operation. Production will be shut down during the unloading operation, and parts of the production facility will be without pressure, the company says.
