Silixa to present at the AGE/BVG/FKPE Joint Workshop on Borehole Geophysics and Geothermal Energy on 22 November 2019 in Munich, Germany

Join us for our presentation at the AGE/BVG/FKPE Joint Workshop on Borehole Geophysics and Geothermal Energy on 22 November 2019 in Munich, Germany.

Athena Chalari, Silixa’s BDM Europe for Environmental & Industrial Applications, will be presenting on Seismic Methods for Geothermal Reservoir Characterization and Monitoring Using Fiber Optic Distributed Acoustic and Temperature Sensor (DAS and DTS).

Enhanced Geothermal Systems (EGS) offer unique monitoring and characterization challenges. The harsh, high temperature downhole environment and heterogeneous nature of discrete hydraulic features, usually governed by discontinuous fractures and faults, requires robust measurement technology with advanced resolution capability.

Borehole DAS installations are often associated with VSP surveys. However, tomographic seismic, earthquake seismology, and microseismic applications have also been demonstrated at geothermal fields.
The spatio-temporal resolution achieved with Silixa’s distributed temperature sensors allows for characterization of hydrothermal processes as well as estimation of thermal diffusivity with depth.

Athena will present on the use of fibre optic distributed temperature and acoustic systems at both hydrothermal and EGS sites.

Silixa presenting at ATCE 2019 in Calgary, Canada on 30 September-2 October 2019

Join us for our presentation at ATCE 2019 in Calgary, Canada where Garth Naldrett, Silixa’s Chief Products Officer, will present on “Cluster Flow Identification During Multi-rate Flow Testing Using a Wireline Tractor Conveyed Distributed Fiber Optic Sensing System with Engineered Fiber on a HPHT Horizontal Unconventional Gas Producer in the Liard Basin” on 30 September 2019 at 14.00 pm.

Garth’s presentation will focus on Silixa’s engineered Carina® Sensing System and its exceptional performance that enables production monitoring in horizontal wells where the thermal and acoustic flow signatures are very small.

He will present the results of a field survey in the Liard Basin, where the flow performance of a horizontal unconventional gas producer was investigated when cluster flow has been detected and quantified. The method employed is the first use of a wireline deployed engineered fiberoptic Distributed Acoustic Sensing (DAS) system for the purpose of production monitoring.

The results of this survey yielded remarkable insights that informed the operator on the completion efficiency and the relationship between the total production rate and cluster activity.

Silixa would like to thank Chevron ETC for their assistance in the Carina® technology development and Chevron Canada for their participation in the field deployment.

Silixa presenting at SEG 2019 in San Antonio, TX, USA on 15-20 September 2019

Connect with us at SEG 2019 in San Antonio, TX, USA on 15-19 September 2019 where we will be presenting on our market leading distributed acoustic sensing solutions and latest applications.

Mahmoud Farhadiroushan, Silixa’s Executive Director, will present on High-resolution Distributed Acoustic Sensor Using Engineered Fiber for Hydraulic Fracture Monitoring and Optimization in Unconventional Completions on Tuesday, 17 September at 10.00 am. (Session: SS 4 DAS Borehole and Microseismic Geophysics for Unconventionals, Location: 303B 5)

The presentation will reveal how Silixa’s Carina® XwellXpress™ monitoring solution can provide insight into reservoirs, enabling operators to improve stimulation and completion designs and deal with the growing concern of interwell communications.

Carina® Sensing System, the next generation of a DAS system utilizing the engineered fiber offers 100x improvement in sensitivity compared to standard fiber and provides unprecedented data quality both on permanent and wireline intervention cables. The intervention wireline cable can be economically deployed for crosswell strain identification on frac hits, microseismic monitoring and time-lapse VSP acquisition. The wireline data can be combined with the permanently installed fibers to provide a wide volume coverage for fracture monitoring and completion diagnostics.

Feeding in the combined near-real-time datasets into the completion workflow, a better understanding of the key operational decisions can be gained to optimize the completion process with a high level of confidence. These measurements lead to better frac design, sequencing decisions and better ultimate oil recovery from the reservoir.

Silixa’s Environmental, Infrastructure & Mining division opens new office in Missoula, MT, USA

Due to the increased demand for Silixa’s distributed sensing-based monitoring solutions for Environmental, Infrastructure & Mining applications, Silixa has opened a new office in Missoula, Montana, USA.

With an ever-increasing burden on the environment and infrastructure due to climate change and the need to safely exploit the world’s natural resources, Silixa’s fiber optic solutions are ideal. They offer high spatial & temporal profiling over large surfaces, long lengths and at locations where conventional point sensing is not applicable or cost effective.

The company’s distributed temperature sensing systems, ULTIMA™ DTS and XT-DTS™, have been the instrument of choice for a wide range of environmental applications, such as soil moisture monitoring, thermocline profiling in lakes and oceans, seepage rate estimation in dams, groundwater-surface water interaction, and fractured rock flow characterization for a number of years. Silixa’s temperature sensing systems have also been adopted by industry for monitoring critical processes where high degrees of spatial coverage, fine resolution and accuracy, and reliability are required.

The company’s phase-coherent DAS systems, iDAS™ (intelligent Distributed Acoustic Sensior) and the Carina® Sensing System, measure the true acoustic field over several kilometers of sensing cable. Acoustic data can be collected with a spatial resolution as fine as every meter, providing a denser dataset than any other traditional point sensor could offer. These advancements are utilized both in active and passive seismic monitoring. Recent advancements in distributed acoustic sensing and the introduction of Silixa’s engineered acoustic sensing system, the Carina Sensing System, have also opened new perspectives with increased geophysical surveying activities including microseismic monitoring and 4D seismic applications for enhanced geothermal systems (EGS) and CO2 sequestration.

The North American branch of Silixa’s Environmental, Infrastructure & Mining division led by Thomas Coleman will focus on continued improvement in services to support increased demand in core application areas, while also facilitating the adoption of distributed sensing for emerging applications across a variety of industries and applications.

The new office is a testimony to the company’s commitment to finding and providing solutions to pressing challenges faced by both industry and the environment.
