Downhole Cable Optical Fiber Logging Cable Oil well gas well logging tool Electrical Cable
Wecan offer Optical Fiber Logging Cable which used for DTS (distributed temperature sensing),DAS (distributed acoustic sensing),DVS (distributed vibrational sensing),VSP(vertical seismic profiling ), real-time monitorin
Optical fiber well logging cable also support temperature monitoring, well condition of the entire cable length covering, and can also be used to remotely control fiber sensor, such as pressure sensors and strain sensors.
Optical fiber downhole cables have optional diameter from 3.2mm/4.0mm/5.6mm/8mm/11mm
What Difference between Optic-Fiber logging and traditional cable logging
The electrical-based sensors used in cable logging can not work continuously in harsh downhole environments (high temperature, high pressure, corrosion, geomagnetic and geoelectrical interference).
The optical fiber sensor can overcome these difficulties. The optical fiber sensor is not sensitive to electromagnetic interference and can withstand extreme conditions, including high temperature and high pressure, strong shock and vibration, and can measure wellbore and wellsite environmental parameters with high precision. At the same time, the optical fiber sensor has a distributed measurement capability, which can measure the spatial distribution of the measured and provide profile information. In addition, the cross-sectional area of the optical fiber sensor is small, which occupies a small volume in the wellbore
