SADAR® Technology
Persistent Subsurface Intelligence
PRODUCT DETAILS
SADAR® is an event-driven, seismic-acoustic monitoring technology solution that classifies and locates subsurface events of interest, automatically and in near real-time.
THE SADAR® ADVANTAGE
Leveraging compact, phased array processing, SADAR® delivers greater range and accuracy via a reduced seismic data acquisition network. By including spatial processing into the analytic sequence, SADAR® is able to detect, associate, locate, and identify events of interest in the presence of elevated noise and clutter.

Why Permanent Microseismic Monitoring Matters
Better visibility into what is happening underground
Subsurface operations are expensive and inherently uncertain. Whether stimulating a shale well, managing waterflood pressure, or monitoring CO2 injection, most decisions are made with incomplete real-time information.
Lower operational risk & stronger Regulatory Position
With permanent monitoring, operators reduce risk of shutdowns or operational restrictions, receive a stronger license to operate in sensitive regions with better defensibility with regulators, landowners, and investors.
Better economics than traditional monitoring
Compact permanent arrays can achieve meaningful monitoring coverage with a simpler surface/deployed footprint. This translates to lower lifecycle monitoring costs, less operational disruption, and improves long-term data continuity
Serve two purposes with one installed system
Support both passive monitoring (listening for natural/induced events) and active imaging (creating subsurface images using vibration sources). This “dual-use” capability increases return on infrastructure investment.
More data-driven capital allocation
Simply put, better data can mean fewer poorly placed wells and better returns on completion spend.
Strategic Advantage for Energy Transition Projects
SADAR provides a differentiator when securing regulatory approvals, JV partnerships, investor confidence or carbon credit validation.
