The use of fiber optic sensing technology for borehole seismic: the ability to simultaneously record VSPs (Vertical Seismic Profiles) in downhole wells, resulting in a significant reduction in acquisition time and carbon dioxide emissions. The challenge faced by researchers was to obtain high-resolution borehole seismic images in downhole wells without deferring production from the platform. The conventional approach, using a downhole geophone method, would have taken a staggering month, leading to a considerable loss in production. However, a solution emerged in the form of the fiber optic borehole seismic system. This innovative approach involved the installation of fiber optic cables in wells, allowing for the recording of borehole seismic data simultaneously along the full length of the wellbores. This technique provides an exciting glimpse into the future of seismic acquisition, highlighting the potential for fiber optics to revolutionize the borehole seismic industry. The ability to capture detailed seismic data in a fraction of the time and with minimal environmental impact opens up new possibilities for exploration and production companies. It should be noted, that the DFOS along with a suitable downhole cables, simultaneously recording VSPs in downhole wells showcases the immense potential of this technology. With reduced acquisition time, minimized carbon emissions, and high-resolution seismic images, it is clear that the future of borehole seismic acquisition lies in fiber optics. We are still in the process of mastering the vertical seismic profiling, but in the meantime you can check out what we do best. So, let us partner and join forces to decarbonize your operations and unlock a new era of exploration and production.

A couple of months ago we published an article about an innovative and multifunctional cable SlickLight. Recently, we conducted a survey to gather opinions on where this cable is best used. The results of this survey are in the chart below to provide insight when deciding where to apply SlickLight. There are no wrong or right answers, instead, we wanted to focus on the key benefits and receive feedback based on your experience in well intervention. Among the answers were flowing wells, gas production wells, gas lift wells and wells with ESP. Gas production wells got most of the votes, followed by gas lift wells and wells with ESP. Because of its simplicity and related efficiency, SlickLight technology is also very convenient for many gas and gas lift wells. For the gas wells this is because of the benefits of having small footprint and perfectly roundness of the cable with corrosion resistant metal jacket. For the gas lift wells other benefits add to it – firstly, access to the entire length of the well is not being hindered by the pump as with other artificial lift techniques. Also, in many cases, the amount of equipment, personnel and operation involved is reduced compared to other well-logging techniques. Even though flowing wells got the least number of votes, however it is also very effective and beneficial to use SlickLight technology for this application. SlickLight is an efficient way to take measurements in flowing wells without shutting them down or disrupting wells operations. Simplified sealing technique at wellhead and cable integrated pressure migration barrier make it one of the most effective options for the flowing and gas wells.

In today’s post, we would like to remind you of the importance of following the principles of sustainable development and share our actions in this area to inspire you to lead an eco-friendly lifestyle, as the measures taken to preserve and support the world around us are something to be proud of. In an era where sustainability is becoming a prerequisite for business success, our aim for a greener future is to balance economic growth with carbon reduction through efficient production and responsible use of resources.

At present, it is difficult to call the earthquake warning industry sufficiently advanced. No matter how hard modern scientists try, the maximum amount of time that people at the epicenter of an earthquake can be warned is still minimal. However, there is a technology in place that is able to recognize an incipient earthquake and notify at-risk people seconds before the shaking starts. This technology is called distributed acoustic sensing, or DAS.

Currently, one of the objectives in investments in DAS systems for seismic purposes is to use acquired data for optimization in designing modern houses and buildings to easier deal with earthquakes.

As at Wires&Bytes we strive to benefit society first and foremost, we feel the contribution in producing fiber optic cables which make an indispensable part of DAS system. Though the field is still in its infancy, DAS could tap into the fiber optic cables buried under our feet as a sprawling, ultra-sensitive network for detecting seismic waves. These cables are used for telecommunications, but they can be repurposed for sensing earthquakes and volcanic eruptions because the ground movement slightly disrupts the light traveling through the cable, creating a distinct signal.

One of the first applications of this technology was demonstrated by Japanese scientists after the Hokkaido earthquake in 1993. They noticed that data from optical cables in the disaster area showed strong vibrations and decided to use this information to create a warning system for possible earthquakes. Subsequently, this technology became more advanced and was widely used in other regions of the world at risk of earthquakes.

For example, here’s how Google’s system ShakeAlert works in USA: when an earthquake occurs, it sends softer seismic waves, known as P waves, through the ground. Not everyone in the earthquake area will feel these, but a network of 1,300 USGS sensors do. When four sensors are simultaneously triggered, they send an alert to a data processing center. If that data meets the right criteria, the ShakeAlert system determines that stronger S waves, the kind that can cause damage and hurt people, could be on the way. It’s then that warning systems will interpret the data and send out alerts.

Wires&Bytes manufactures a range of cables for structural health monitoring which can be integrated into sensing systems to detect earthquakes, volcanic eruptions and other ground movements. The most versatile of the cables in this group is Non-metallic MultiSense, as it combines all types of distributed sensing (DTS, DAS, DSS) in one design and it is also characterized by increased acoustic sensitivity.

In the oil and gas industry, inflow control valves play a critical role in well completions. These valves are essential for regulating the flow of fluids into a well, either partially or completely restricting it. Typically, they are positioned along the reservoir section of the well completion, and each valve is separated by a packer. This configuration enables individual control of each valve from the surface, allowing operators to maintain optimal flow conformance and prevent the ingress of undesired fluids into the wellbore.

To facilitate the operation of these inflow control valves, a permanent downhole cable is utilized as an integral part of the system. This cable serves as a conduit for transmitting electric and hydraulic commands from the surface to each valve. Wires&Bytes ProTEC cable family offers an ideal solution for the deployment of the inflow control valve system. Notably, these cables exhibit high resistance to aggressive environments commonly encountered in oil and gas operations. Additionally, they are fully compatible with standard fittings and can be securely attached to oil-well tubing due to their square shape.

By leveraging the ProTEC cable family from Wires&Bytes, operators can ensure reliable and efficient performance of their inflow control valve systems in challenging oil and gas environments. The use of these cables contributes to enhanced well control, improved production optimization, and increased operational efficiency.

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.
