Enhanced production logging was performed using fiber-optic cable cemented behind the casing to assess well and field performance.
First, in view of the slow transmission rate of the logging cable, an advanced high-speed cable transmission module is adopted.
Optiq solutions can be seamlessly integrated with any existing fiber-optic infrastructure (such as in pipeline integrity monitoring) or by
