We show that fiber-optic sensing opens up new possibilities for geophysical measurements with a broad range of applications in well logging and seismic exploration and monitoring.
A carbon-coated and bellow-packaged optical fiber sensor for high pressure and high temperature monitoring in downhole applications is developed and successfully field-applied in an oil
This paper proposes a reflective fiber-optic sensor network for multiparameter state monitoring in oil and gas wells. The network is composed of a ground-based sensing signal
Previous of ATV systems sent an analog signal up the logging cable that was displayed and photographed on an oscilloscope. Nowadays, the analog signal is digitized downhole, and the digital
To meet the logging requirements of ultra-deep wells, this paper first provides a detailed introduction to the design structure and performance indicators of the instrument.
Abstract. This paper introduces Distributed Fiber Optic Sensing (DFOS) as an innovative solution to achieve production profiling in reservoir monitoring. Fiber optic cable is deployed into the
The method of simultaneously distributed fibre optic measurement of temperature and acoustics was used for the first time and proved successful in the investigation of the borehole integrity.
Suitable for oil wells, gas wells, coal mines or under high temperature conditions. The cables marked with Dry; They are a series of cables in which the typical water blocking the intermediate tubes
Enhanced production logging was performed using fiber-optic cable cemented behind the casing to assess well and field performance.
Abstract: Fiber optic cables have the advantages of high temperature resistance, high pressure resistance, corrosion resistance, and high accuracy in measuring temperature DTS data. They are
