WILLOWSTICK

Water Resource Technology

Geophysical subsurface water sourcing, flow mapping & dam leak detection

DAMS RESERVOIRS & CANALS

Fixing leaks in dams has always been a stressful venture. Not only are current methods expensive and slow to yield results. They often will resort to “trial and error” methods that may further strain the integrity of the structures rather than fix it.

Here at Guardian/Willowstick we offer our own solution. By using our patented state of the art geophysics and hydro-physics technology...

ENVIRONMENTAL
‍‍

Our system is the most adept in the world at accurately mapping complicated flow paths of subsurface pollutants. Ensuring a more complete remediation that has otherwise been impossible to reach.

In the past, to acquire this level of vision would have required, aging technology that is incredibly expensive, such as dry drilling. The WIllowstick method provides the solution.

MINING

In the mining sector, water management presents significant challenges. Adequate access to water is crucial for initiating mining operations, yet addressing water-related issues often constitutes one of the final hurdles prior to obtaining financial clearance for mine reclamation and closure endeavors.

For mine owners, managers, and operators we have subsurface water sourcing and flow mapping technology that helps manage risk and provides solutions.

WELL SITING

Using both of our proprietary methods in MSR and Radiometric Gamma, we search for different geo-mechanical, water presence indicators and of course, our in house geophysicist teams to find accurate results for well sites.

The technology is not just leading the charge when it comes to Well Siting. No one does it quite like we do. With a 95% success rate in our MSR well siting we are active all over the world in trying to find wells that top local wells in output.

WATER WELL SITING REVIEWS

We completed our survey and delivery of the final report in May 2024. On July 1st, their existing well ran dry. Their only water was what was left in their cistern.  July 8 the driller showed up onsite.

During the drilling, they hit some methane gas at about 40'.  Once that cleared up they continued drilling.  At about 200' they got a tiny bit of water and then choose to keep drilling to my estimated depth of 300+'. They hit huge water at 328 feet with artesian pressure.  The water is super clean with no issues.

“The depth of the fracture zone is correlating very well with your MSR survey.  Thanks again for your help. “
- Project Manager 1 of Kanosh Well
Well Site
“ Kanosh was a smashing success.  We tested the well capacity last week.  We sustained a 1,000 gpm flow with only 14 ft. of drawdown.  Based on the step test, Dao is estimating the specific capacity of the well to be north of 3,000 gpm.  I couldn’t be happier with how things turned out.  The town is very pleased.”

Well Site
“The driller informed me that we have gotten a little bit of water at about 200 feet and asked me what I would like to do, while also hiniting that we should stop drilling. I told the driller that the [geophysical] report says 300+ feet so please keep drilling.  At 328 feet, exactly where you said to drill to, we hit a lot of water, and it was artesian."
Preston, Idaho
Well Siting
"After hitting the artesian water at 328 feet, the driller was so amazed that they wanted to know everything about Willowstick. We have now had neighbors and other residents in the area stopping by our house to ask us who did the survey and who drilled the well.

The cost for the survey was 100% worth the result we obtained"

OUR METHODS

Our proprietary method involves the use of a low voltage, low amperage, alternating electrical current that energizes the groundwater through electrodes. This setup exploits the natural conductivity of groundwater compared to surrounding materials, allowing the electric current to travel along water-bearing features.

As the current flows, it generates a magnetic field, which is then detected and analyzed using our specialized instruments at the surface. This data is carefully normalized to highlight anomalies indicating areas where the magnetic field exceeds expected levels.

Our findings enable us to accurately locate seeps, leaks, and preferential flow paths, significantly reducing exploration and remediation costs while providing our clients with detailed and reliable groundwater system characterization

WHO WE ARE

We are a geophysical technology company that specializes in identifying, mapping, and modeling preferential groundwater connection paths. Our patented technology operates much like a medical angiogram, offering a non-intrusive method to visualize and understand groundwater flow paths beneath the surface.

This advanced approach allows us to serve a diverse range of clients, from environmental agencies to large industrial entities, providing them with precise and actionable insights into their subsurface water systems.

With over 130 clients worldwide, we have established our company as a global leader in groundwater analysis, helping property owners and managers pinpoint specific problems before they escalate.
