It provides many benefits, such as the ability to perform different measurement types (e.g., temperature, acoustic, strain) using a single cable with multiple fibers. Additionally, it enables simultaneous

Monitoring cold water injections for reservoir characterization using a

We installed fiber optic cables into a geothermal production and injection well and used DTS data measured after drilling and during shut-in after cold water injection to observe the

Applications of Distributed Fiber Optic Strain Sensing for Real-Time

An experimental study was conducted to validate the field observations. Using distributed strain sensing, we can extract relevant downhole information (such as fluid/material changes) in real-time without

A Real-Time Fiber Optical System for Wellbore Monitoring: A Johan

Paper presented at the SPE Offshore Europe Conference & Exhibition, Virtual, September 2021. Fiber Optic (FO) sensing capabilities for downhole monitoring include, among other

New methods in geophysical exploration and monitoring with DTS and

Apart from boreholes, fiber-optic sensing also opens up new possibilities for geophysical measurements at surface, especially since extensive networks of fiber-optic cables for telecommunication and data

distributed fiber-optic sensing

16 wellbore fiber-optic installations can be conducted by mounting the sensing cable to a rigid structure ontrolled landing of the cable. We analyze a 18 geothermal well with a 3.6 km long fiber-optic

Distributed fiber-optic temperature monitoring in boreholes of a

In the presented project, three boreholes of a seasonal geothermal energy storage with a vertical depth of down to 500 meters were instrumented with distributed fiber-optic sensors.

Fiber-optic technologies and methods for downhole monitoring

Optical time-domain reflectometry (OTDR): measurement of backscattered light for many sampling points along fiber. Phase-OTDR: phase of backscattered light changes as the fiber is stretched, e.g.

Permanent Fiber-Optic Installation in the Reservoir Section of a Deep

In Germany''s largest geothermal project, a fiber-optical cable was permanently deployed to total depth together with a pressure sensor located 50m above the reservoir.

Applications of Distributed Fiber Optic Strain Sensing for Real-Time

To analyse the downhole performance of mud displacement and cement slurry during the cementing processes, this work focuses on real-time well monitoring technologies using fiber optic cables which
