Silixa’s DTS to help figure nature’s response to spiralling CO2 levels

Silixa is collaborating with the University of Birmingham and the Birmingham Institute of Forest Research to fill the gaps in knowledge about climate change related to higher CO2 levels.

An outdoor laboratory has been created in a Staffordshire forest where scientists are artificially injecting CO2 into the air to study the effects of a CO2-enriched environment on trees and the ecosystem as a whole.

CO2 is the source of the carbon that plants turn into organic compounds and researchers assume that heightened levels of carbon emission may have a fertilizing effect on plants boosting growth increasing their ability to buffer climate change.

However, plants’ growth is the result of a complex interplay of multiple factors, amongst which water availability is particularly critical. Faster growing plants may draw more water than the soil can currently absorb, leading to increased soil dryness.

Silixa is helping scientists to determine the amount of water available in the soil using active distributed temperature sensing techniques (Active-DTS).

Active-DTS combines distributed temperature measurements with a heat pulse sent along the optical cable. Soil water content profiles at sub-metre scale can be extracted by analysing the heating and/or cooling phases of a several kilometre long optical cable buried in the soil.

The information provided is invaluable to researchers in finding answers to how the ecosystem will respond to increased CO2 levels and what the consequences will be.

Silixa joins forces with research institutes across Europe to increase field experience relevant to CO2 storage

A new project named ENOS (ENabling ONshore CO2 storage in Europe), uniting 29 organisations across 17 countries, was launched in September 2016 with the objective to increase field experience relevant to geological storage of CO2.

CO2 capture and storage (CCS) is a key climate-change mitigation technology and it offers a solution to bridge the gap to a low carbon future until the use of fossil fuels is discontinued. To date, some 50 Mt of CO2 has been safely stored underground. However, this represents only a small step (0.06%) towards international 2050 targets.

The project, coordinated by BRGM (France), strives to enhance the development of onshore CO2 storage as well as to improve techniques and tools that are used for site monitoring. Several field pilots in various geological settings will be studied in detail and best practices will be developed that stakeholders can rely on. In this way, ENOS will demonstrate that CO2 storage is safe and environmentally sound and increase the confidence of stakeholders and the public in CCS as a viable mitigation option.

Silixa’s fibre optic DTS and DAS monitoring systems will be installed in several field pilots. Utilising iDAS and a permanently installed fibre optic cable in a CO2 disposal or observation well, it is possible to acquire on-demand, time-lapse borehole seismic data which can describe the growth of the CO2 plume within the reservoir. Concerns over the integrity of the cap rock or the wellbore can be addressed by passively monitoring for potential micro-seismic events. A permanent DTS system can continuously monitor the injection of CO2 in real-time, detecting leaks and facilitating gas migration.

ENOS will run until August 2020.

Distributed acoustic sensors gaining momentum in downhole multiphase flow measurement

Distributed acoustic sensing makes it possible to monitor the acoustic field along the entire length of a standard fiber optic cable, hence becoming a recognized solution for high accuracy in-well flow surveillance, including downhole multiphase flow measurements.

Garth Naldrett, Silixa’s Chief Product Officer, presented on Silixa’s latest developments in multiphase flow metering at the Multiphase Metering and Fibre Optics Monitoring – Recent Developments and Challenges SPE Workshop in Dubai, UAE on 22-23 March 2017.

His presentation, titled From Distributed Measurement to Multiphase Flow, discussed how distributed fibre optic measurements allow the physics to be constrained in space and time and how interpretation errors can be reduced by deriving additional information from DTS and DAS.

Examples of measurements that can be derived from DAS include the speed of sound, the use of Doppler Shift and the direct measurement of flow eddies, which allow better determination of flow rates and density.  Garth’s presentation also discussed the application of these derivatives, described the methods employed and provided case studies of downhole multiphase flow measurement.

Garth also presented on Industry Solutions for Distributed Sensing Big Data Management, providing an overview of the data types generated by a typical fibre optic monitoring system and offered  insight into the range of data rates and data volumes generated.

Increased use of distributed fibre optic technology linked to spending cutbacks

Silixa achieved a number of milestones in proving distributed acoustic and temperature monitoring systems during 2016.

The use of Silixa’s iDAS™ technology in upstream oil and gas applications has increased for borehole seismic applications. Several surveys were conducted where fibre optic enabled wirelines were conveyed into deep wells, both offshore and on land, allowing seismic data to be gathered from along the entire cable length. This has demonstrated significant benefits over geophone acquisition enabling a much wider aperture sensor array as well as accessing wells where geophone deployment has proven difficult or no possible.

2016 also saw the first full scale repeat seismic (4D) offshore survey with high resolution iDAS data. This was used to compliment ocean bottom node data from the same survey period.

The iDAS and ULTIMA™ DTS gained more traction in the US Shale market despite the unfavourable economic conditions; most notably Silixa has demonstrated that when optical fibres are installed in the well this technology opens up access to various types of data at all stages of the well, such as VSP, cement evaluation, frac monitoring, microseismic detection, flow back and production profiling.

Silixa has also closely assisted an operator to implement distributed acoustic sensing for the detection of sand entry in producing wells as part of a wider sand management effort. This project complements data acquisition with software and hardware development to create a truly integrated and scalable system.

Production monitoring remains one of Silixa’s key application goals with the iDAS and ULTIMA DTS technologies. To this end Silixa has participated in a multi-well offshore trial focussing on successful installation of fibre optic cables in mono-bore completions and subsequently acquiring high quality acoustic and temperature data for use in the interpretation of production conditions.

The use of Silixa’s technologies in environmental applications has also increased. In 2016 several active distributed temperature sensing (Active-DTS) surveys were conducted in the United Kingdom. Active-DTS is a technique that combines distributed temperature measurements with a heat pulse sent along an optical cable containing copper wire. Soil water content profiles can be extracted from temperatures trends during heating and/or cooling phases. Measurements utilised the ULTIMA DTS  and XT-DTS™ and the data proved to be invaluable.

Fibre optic based distributed sensing technologies have also gained a firmer ground in geothermal applications. A 9 km surface array and 400 m downhole cable were installed at an operational geothermal field and power plant in the United States to record a continuous seismic and temperature dataset for 15 days. The aim was to use poroelastic tomography to characterize the geothermal reservoir response due to changes in pumping and injection. The collected seismic data will be used to create a 4D model of the reservoir during the monitoring period. Information gained about the reservoir can be used to guide the geothermal plant future operations.

As part of the EU FPA ZONESEC project, Silixa has started working with its partners on an Integrated Project that aims to integrate affordable ground and airborne sensor technologies for the surveillance of large spatial areas of high economic values in Europe.

Having contributed to the overall system architecture, Silixa began the integration of its intelligent Distributed Acoustic Sensor (iDAS) to the ZONESEC platform. An on-site integration pilot has already been successfully completed at ACCIONA’s premises in Spain. A second on-site integration pilot will take place in December, 2016 in Athens.

Using ULTIMA DTS and utilising existing single mode fibre optic cables, Silixa has also deployed a permanent distributed temperature monitoring system in the Middle East, to continuously monitor seabed temperature along the first 30 km from an offshore platform. The system records and transfers distributed temperature data in real-time to the onshore control room.  Additional platforms are expected to be instrumented with Silixa’s monitoring system in 2017
