Current pre-drilling Geothermal Exploration methods are time intensive, costly and 
 DO NOT achieve active reservoir imaging. The Data is Insufficient, the Risk is TOO HIGH.

Geothermal exploration is high risk, TERT is able to reduce this risk considerably as well as the cost and time of exploration:

TERT covers datasets that conventional methods do not achieve; boots on the ground are NOT required at this stage. 

Boots on the ground are used for confirmation of the TERT results.

The same principles are used as for oil & gas exploration, the main difference is that we are looking for different densities, different patterns that reflect the minerals that we are looking for.

For successful geothermal exploration, TERT uses two main exploration tools as follows:  STeP® (Sub-Terrain Prospecting) and OFL (Open Fracture Locator).

The deployment of STeP® to define the geothermal system will validate the geothermal potential with the status of possible, transfer them into the proven status, improve its projects’ economics through reduction of exploration and drilling risks. 

STeP® produces analytical results that detect subsurface information from information captured at the surface.

is able to analysis the saterlitte derived data for what is required for a geothermal system, this includes inferred permability.

Open Fracture Locator (OFL) 
is a passive seismic technology that uses the principle of low power natural seismic emissions of the Earth to ascertain fluid type and saturation in reservoirs.  These emissions are generated in fractures opening and collapsing during the lunisolar tides and associated gravity changes.  In simple terms, the Earth is known to have a “breath” effect as it orbits the Sun and the Moon orbits the Earth.  Geophones are deployed at the surface and collect such acoustic events during thirty calendar days using the seismic station and other computing equipment.  

OFL is a confirmation and monitoring tool that can be used during the lifetime of a geothermal system. 

TERT generates a report that identifies the zones of water saturation and its movement within the reservoir.

OFL will help to maximize the reservoir life/production potential for any geothermal area that is either in production or will be in production.

OFL Results

In summary: OFL is used to determine the presence of water in the subsurface, reservoir dynamics, and depletion.

Geothermal reservoirs are complex and ever-evolving geological features that require an understanding of their composition and change.  OFL can be used during exploration as well as production stages. 

A better understanding of the reservoir dynamics can ultimately help plan for more effective injection of fluids back into the subsurface. 

OFL can help to better understand the reservoir volumetric changes, thermal declines due to the incorrect placement of the injection wells as well as the overall development strategy.

Such images are assembled into a series to render an animated result showing the reservoir dynamics and fluid movements over a period of one month.
