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

Silixa to present at the 2nd International Conference for Fibre-optic and Photonic Sensors for Industrial and Safety Applications (OFSIS 2017) in Brisbane, Australia on 8th – 10th January 2017

Daniel Finfer, Silixa’s Head of Applications Development, will be presenting at OFSIS 2017 in Brisbane, Australia on 8th – 10th January 2017.

The presentation titled Flow monitoring of industrial slurries and oilfield production using the Metering intelligent Distributed Acoustic Sensor (MiDAS) will reveal the results of the world’s first pilot installation for a nonintrusive, multizone flow metering system based on distributed acoustic sensing (DAS). (Authors: Daniel Finfer and Mohammad Amir (Silixa Ltd.); Phil Newman, Steve Amor, Neil Rein, Clinton Naicker (Anglo American PLC)

Silixa was commissioned by Anglo American to execute the DAS-based pilot installation at eMalaheni Water Reclamation Plant (EWRP), where 30 ML per day of Acid Mine Water (AMD) is reclaimed from local coal mines for use as both drinking water and within mining operations.

During this pilot, 6 separate liquid flow zones in 3 different regions of the plant were instrumented using a single optical fiber.  Zone 1 of the installation featured a large scale HDPE water supply line feeding water from the surrounding mines into the plant. This pipe is metered continuously using a conventional magnetic flow meter, making it straightforward to obtain reference flow rates. The HDPE flow line in Zone 2 handles water processing slurry, the solids content of which varies over time. Zones 3-6 were installed along on a multibranch stainless manifold handling high rate liquid flow. Reference data in this last region of the plant was obtained via a clamp-on ultrasonic meter.

During the course of the 6-week pilot, flow rates were monitored continuously using the MiDAS system, and automatically uploaded from the plant in rural South Africa to the Silixa Headquarters in London. MiDAS output was compared with the rates obtained by Anglo American using conventional sensors. It will be shown that the sensing layout was straightforward to install, and that the output is in good agreement with conventional sensors.  Opportunities and challenges for large scale future applications of this nonintrusive system will be considered.

In addition to applications on industrial slurries as described above, Silixa will describe recent experience gained using this same opto-acoustic sensing architecture for the measurement of multiphase flows in the oil and gas industry. It will be seen that the MiDAS flow monitoring technology offers a robust approach to flow rate measurement and composition trending for oilfield production across the full range of gas void fraction (GVF) and water in liquid ratio (WLR).

Silixa to present at the 4th European Flow Measurement Workshop in Noordwijk, Netherlands on 29-31 March, 2016

Silixa will be presenting material co-authored with Roxar on Multiphase, Multizone Flowmetry via Eddy Tracking and Sound Speed Measurement using a Distributed Acoustic Sensing System at the 4th European Flow Measurement Workshop in Noordwijk, Netherlands on 29-31 March, 2016.

Flowmetry using DAS can be performed unobtrusively via a single sensing fibre wrapped densely on the exterior of a pipe. Using this geometric arrangement, DAS output can be interpreted for information relating to both eddy convection and sound speed data in upstream environments.

Daniel Finfer, Silixa’s Head of Applications Development, will share the results of a multiphase flow measurement test where three DAS-enabled sensing zones were installed in series with a ROXAR multiphase flow meter (MPFM) within a three-phase flow loop. The output from these experiments showed good agreement between the DAS and MPFM across a broad range of flow speeds and flow types, including single phase liquid and gas flows, two phase liquid-gas and liquid-liquid flows, and three phase oil-water-gas flows.

The 4th European Flow Measurement Workshop provides a forum for the most experienced engineers and specialized measurement institutes in flow measurement to share their latest developments and challenges in flow metering systems and liquid flow. End users can update their knowledge and share their best practices and challenges on utilizing these flow meter systems.
