Here we outline some new technologies in this context within case studies from different research projects including permanent installation of fiber-optic sensor cables behind casing, monitoring of high-temperature wells, a hybrid wireline logging system, and. 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 (gelatin, water swelling tape or powder) is replaced with a solid foamed thermoplastic elastomer. Beginning with optical ground wire (OPGW), introduced in 1984 as AFL's flagship product, the line has expanded to include fiber-optic cabling solutions. These are used in the world's harshest environments, including those above ground, below ground and even underwater. This paper introduces Distributed Fiber Optic Sensing (DFOS) as an innovative solution to achieve production profiling in reservoir monitoring. Fibercore, in conjunction with selected partners, offer wireline logging cables that utilize Fibercore's hydrogen resistant, high temperature fibers. Logging, also called geophysical logging or mine geophysics, is a method of measuring geophysical parameters by using geophysical properties such as electrochemical properties, conductive properties, acoustic properties, and radioactivity of rock formations.
