XDT on Geothermal Exploration
Understand Seismology, and you’ll
Understand the Subsurface
You don’t need to drill to know what's going on
beneath your feet. XDT uses passive seismic
signals to accurately describe the subsurface.
XDT has great experience with few staff. Therefore, we
can offer expert services at low costs.

Geothermal exploration is more than
finding where the heat is. Its finding
the best way to it.

XDT provides innovative and proven
techniques of analysis. There aren’t any
black boxes here.
Shear wave splitting – can be used in identifying fissures and
other anisotropic elements. Click the earthquake circle below.
When the shear waves generated from the earthquake
propagate through the cracks, polarization occurs. The
different arrival times from the split s-waves can be
measured to model where the foliation or fissures occur.
Wave Attenuation and Velocity – used to identify subsurface
characteristics. Click the earthquake circle below.
When passive seismic waves propagate through differing
bodies, attenuation and changes in velocity occur. The
Subsurface Body different arrival times and amplitudes can be measured to
model the properties and locations of the subsurface bodies.
Not only are our techniques innovative,
but our software is one of a kind.
