Whatever your monitoring needs, we’ve got you covered


Seismic monitoring has been our core business for over 30 years.

Our complete, turnkey induced seismic and microseismic

monitoring systems are engineered for autonomous operation

and maximum reliability. They include the best instrumentation

on the market — the same systems used in dozens of national and

regional seismic networks as well as mission-critical applications

that include tsunami warning, volcano monitoring and earthquake

early warning. But Nanometrics is about more than just equipment.

As one of the world’s largest seismic network operators, we offer

proven network design methodology, station deployment and

network maintenance capabilities and extensive in-house data

processing and analysis experience… everything to expertly

and cost-effectively meet all your monitoring needs, including

compliance with the latest regulatory requirements, so you can

focus on your core business.

Despite the increased station density in areas where previous

seismicity has been recorded, data from public networks do not

have the resolution or accuracy to drive operational decisions. We

offer a fully autonomous turnkey monitoring solution using our

proprietary broadband arrays with the latest state-of-the-art event

detection, communication and data processing technology. We’ll

manage the network design, installation, commissioning, data

acquisition and processing to enable you to satisfy your technical

requirements and meet or exceed monitoring regulations, right out

of the gate.

Our scientific and operational experience in earthquake

seismology means we can work closely with industry groups and

researchers to stay abreast of regulatory discussions and ensure

our systems are ready for any potential changes in regulations.

This includes the complementing current magnitude-based

protocols with ground motions, since we compute ground motions

in addition to source parameters as part of standard monitoring

deliverables.

INDUCED SEISMICITY MONITORING (ISM)

in earthquake seismology

leading edge of technical

innovation and evolving

industry demands.

Our stations

Our autonomous stations have a minimal environmental footprint,

making for easy permitting. Each station streams data via a

cellular data connection to our cloud-based data center. Our

stations are designed for maintenance-free, continuous operation

and uninterrupted data streaming all year round in any weather

condition. And we ensure cost effectiveness, by using the minimum

number of stations to meet your monitoring criteria.

Our data center

Our 24/7 cloud-based data center offers data recording,

transmission, processing, analysis and event notification services.

The center is staffed with experts ready to provide data analysis at

a moment’s notice for consultation during operational activities.

Data arriving at our data center will be processed in near real-time

(for automated real-time processing), manual post processing

and optional enhanced processing, with data delivered directly

to your office or pad site. You also have the option of receiving

notifications within minutes if an event meets a certain criteria or

threshold.

Our software

As part of our ISM solution, you’ll receive access to a secure,

customized and branded copy of Athena, our easy-to-use data

management, event cataloging and notification system that can be

accessed via any web browser, anytime from anywhere.

You can browse the up-to-date event catalogue, view all recorded

event source parameters and waveforms, select and download

sections of the catalogue, plot frequency/magnitude relationships

for event clusters, examine maps showing distribution of

ground motions from each recorded event and

track network seismicity rate to manage risks

associated with induced seismicity in real time.

Athena also allows the distribution of near real-

time and fully processed earthquake data via a

wide range of channels or routes including email,

SMS, RSS, Twitter, web pages, and Google Earth

or GMT screen display.

PFI, or passive frac imaging, is a cost-effective hydraulic fracturing

monitoring service that tells you the when, where and how big of

a microseismic event. Typically monitoring these tiny earthquakes

means a big expenditure, but with our PFI service, you’ll get the

information you need at a fraction of the price of costly downhole

monitoring.

Our PFI service includes:

• Network performance modeling and design

• Turnkeyfielddeploymentanddecommissioning

• Autonomous high-quality (low self-noise and high dynamic range) 3-channel recorders

• Off-line recording and data playback following station retrieval

• Industry standard microseismic deliverables

• Complete data processing (4 to 5-week processing time) with fullyexplainedprocessingworkflowanddeliverables

And because our PFI solution is highly scalable, it’s easy to

integrate ISM or include additional services to suit your needs.

Our subscription arrays

are the most cost-effective

way to monitor seismicity

and manage risk. In

fact, the performance

of our subscriber arrays

exceed current regulatory

requirements.

Why subscribe?

• Higher station density and higher monitoring resolution than public arrays

• Flexible subscription term

• No installation or decommissioning costs

• No array expansion costs

• Best-in-class instrumentation

• The same level of service as private arrays

We were the first to introduce the subscriber array concept.

We own the equipment and take care of its installation and

maintenance. We pay for new stations as needed to cover new

subscriber land holdings.

SUBSCRIPTION ARRAYS

1stto introduce subscription arrays

Higher monitoring resolution is

the key to using seismic data to

assist with real-time risk man-

agement.

Our subscription array is located

in the Duvernay region. Ask us

about our subscription array

options in the U.S.

Each subscriber receives:

• High-quality baseline, frac and post completion data, supplemented by data from public stations in the area

• 24/7 central site data acquisition, processing and notifications, including event source parameters and ground motions

• Access to your own private web portal (Athena) for an unlimited number of users. And only you will have access to the data about smaller events on your holdings.

Optional add-ons:

• Shake maps

• Raw waveforms

• Advanced seismic processing:

o Subspace catalogue enhancement

o Double difference relocation

o Moment tensor inversion

o Deployment of additional subscriber-specific temporary stations

Improved catalogue and

accuracy with private arrays

= better risk management.
