The Willowstick Instrument™ measures the magnetic field produced by the distribution of electric current to track patterns that help characterize preferential groundwater flow. Our Magnetometric Resistivity (MMR) technology differs markedly from traditional resistivity and other electromagnetic (EM) methodologies. First, it capitalizes on the fact that water content is a dominant factor in enhancing the subsurface electrical conductivity of soil and rock. Second, by directly energizing a conductive groundwater medium with strategic electrode placement, the electric field can more effectively “illuminate” the target of interest with less interference from overlying layers, and 3) Our instruments, pattern recognition software, and robust processing power enable us to rapidly iterate and change the direction of energy bias in real-time. This “adaptive mapping” capability enables our models to be precise representations of in the ground reality. The Willowstick process is protected by patent process No. US 8,688,423 and other patents pending. 


Over the past few years Willowstick has taken significant steps forward in terms of refining its instruments used to collect and map a wide variety of groundwater reading and the software algorithms and filtering capability necessary to see groundwater activity with much greater acuity than ever before. The order of magnitude increases in computing power have made it possible for us to recognize and amplify very faint signals at greater depths than previously possible. Furthermore, the breadth of our technology applicability has expanded from tracking water leaks in dams to oil and gas applications, from there to addressing mining and refining water problems, and finally to a variety of environmental applications that presuppose the ability to track contaminant transport through water bearing zones. 


Today, Willowstick has completed over 300 groundwater characterization projects as all over the world. Willowstick is happy to count as its clients the most sophisticated clients and consulting engineers around the world.
