During a fracturing treatment, various types of data can be obtained by monitoring the behaviour of fluid injection into the formation. This data can provide valuable insights into the efficiency and effectiveness of the fracturing process, as well as help to identify potential issues or areas for improvement.

One important aspect of this monitoring is evaluating the cooling and warming effects that occur during and after the injection. As fluid is injected into the formation, it cools the surrounding rock, which can be detected and measured using specialized equipment.

DTS is a sensing technology that uses fiber optic cables to measure temperature changes along the length of the cable. These cables are typically deployed along the wellbore and are capable of measuring temperature changes at very high spatial resolutions. The fiber optic cable consists of a core made of a high-quality optical material such as silica, which is surrounded by a cladding material with a lower refractive index. The cable is then encased in a protective coating to prevent damage and ensure durability.

During hydraulic fracturing, the DTS fiber optic cable is placed either permanently, like ProTEC designs, or temporarily, like SlickLight family cables along the length of the wellbore. In a permanent installation, the cable is attached to the outside of the casing, while in a temporary installation, the cable is lowered into the wellbore on a wireline and then retrieved after the fracturing treatment is completed.

As the fracturing fluid is injected into the formation, it cools the surrounding rock, and this cooling effect can be detected and measured by the cable. By analysing the temperature data collected by the DTS, engineers can gain insights into the geometry, orientation, and extent of the fractures, as well as identify any issues such as fluid loss or preferential pathways.

For example, temperature data collected by DTS can be used to determine the rate at which the fracturing fluid is propagating through the formation and the location of the fracture tip. This information can be used to optimize the fracturing treatment and ensure that the fracture is growing in the desired direction.

In addition to monitoring injection behaviour during hydraulic fracturing, SlickLight family of cables can also be used for other applications such as wellbore monitoring, production monitoring, and reservoir characterization. Overall, the high spatial resolution and accuracy of Wires&Bytes cables make them a valuable tool for analysing temperature changes and gaining insights into complex geologic systems.

These cutting-edge cables are designed to enhance the performance and efficiency of well operations, making them an indispensable asset for any oil and gas company.

With these high-tech cables, operators can easily access and monitor downhole equipment, ensuring optimal performance and production rates. The SlickLight family of cables is specifically designed for easy removal and replacement, enabling operators to address any issues or faults quickly and easily without the need for costly and time-consuming well interventions.

The optical fibers in these cables are highly precise and accurate, providing real-time data transmission from downhole to the surface. This enables operators to make better-informed decisions and optimize well performance for maximum productivity and profitability. The data transmitted can include critical information such as pressure, temperature, flow rate, and other parameters, which are essential for maintaining the integrity of the well and achieving peak performance.

Moreover, the use of high-performance optical fibers in these cables ensures that the data transmitted is immune to electromagnetic interference; and resistance to downhole harsh conditions makes the cables highly reliable and accurate. The ability of these cables to transmit data over longer distances without degradation makes them ideal for use in deep, complex wells.

Overall, the use of retrievable optical fiber cables for well interventions represents a significant improvement over traditional method. Operators can reduce downtime, enhance operational efficiency, and optimize well performance through more precise and accurate monitoring and control. With the advanced technology and exceptional specifications and design of Wires&Bytes SlickLight family of cables, it’s clear that they are an indispensable investment for any well intervention or well logging operations.

Wires&Bytes fiber optic SlickLight technology can play an important role in enabling intelligent interventions by providing real-time monitoring and control capabilities. With fiber optic SlickLight, data can be transmitted in real time from optical fiber which acts as a sensor to the surface, allowing operators to make informed decisions and take timely action based on changes in temperature, flow, acoustic and other performance metrics.

One way it can help with intelligent interventions is by enabling the use of downhole flow control devices. These devices can be monitored remotely using fiber optic SlickLight, allowing operators to adjust flow rates and optimize production in real time.

Fiber optic SlickLight can also be used to monitor the performance of downhole equipment and identify potential issues before they become major problems. For example, changes in temperature or flow can indicate a blockage in the wellbore or a malfunction in the intervention equipment. With real-time monitoring using fiber optic SlickLight, operators can quickly identify these issues and take corrective actions before they cause significant downtime or production losses.

Wires&Bytes fiber optic SlickLight technology can help enable intelligent interventions by providing real-time monitoring and control capabilities that allow operators to make informed decisions and take timely action based on changes in downhole conditions. This can help improve well performance, reduce downtime, and increase overall production efficiency.

 

Wires&Bytes fiber cables are used as an integral part of Distributed Fiber Optic Sensing (DFOS) solutions.

Based on the doctoral thesis by Bridges & Structural Engineer, António Barrias, there is a variety of fields where DFOS solutions are deployed: oil and gas industry, safety and security, power and utility, civil engineering, etc.

A few years ago oil and gas industry was an indisputable leader of DFOS application in Europe.

The forecast by Visiongain António referenced in his work demonstrates the expected shift of application in Europe when major share of Oil & Gas in 2018 is supposed to give space to other fields, in particular, civil engineering, by 2028.

This means that Structural Health Monitoring will eventually become an equally important area of application of sensor cables as oil and gas industry, and the value of such products cannot be underestimated.

Wires&Bytes offers a range of cables specifically designed for SHM purposes, and more R&D activities are ongoing.
