SEARCH METHODS
Here we want to explain what each of our methods consists of in order to reach reliable results by contrasting data and results from different techniques. With this procedure we try to give a high degree of reliability.

MAP STUDY BY TELERADIESTHESIA
Once we have located your plot on the map, we carry out a first viability study. We study the geology and topography as well as the veins and aquifers we find. If this result is satisfactory, we can move on to the next search method.


RADIESTHESIA STUDY ON THE GROUND
At Saurí Online, we travel to your location and carry out a radiesthesia study on the ground.
We always recommend complementing the remote telerradiesthesia study with an on-ground radiesthesia study to mark the exact drilling point.
With this on-ground session we will define the best location and reliability of the extraction point, depth and approximate flow rate.
geophysical study on the ground
1. MT (magnetotelluric resistivity)
We have two devices that use MT technology (capture of natural passive terrestrial magnetism). The Earth generates an internal magnetism that, when rising to the surface, presents variations in intensity.
In areas with high resistivity —such as impermeable rocks— the magnetic signal arrives with less intensity. In contrast, in areas with fractures, faults or more permeable materials, this magnetism is transmitted more easily to the surface.
This technology allows us to detect differences in subsoil resistivity. Water mainly circulates through faults (both vertical and horizontal), which have lower resistivity.
In this way, with these two devices we can validate that the points identified by radiesthesia or telerradiesthesia coincide with low resistivity zones.


1A. mt geo(pqwt)
This device allows us to visualize the geological structure of the subsoil. It does not directly detect the presence of water, but rather the geological formations that may contain it or favor its circulation.
Here are two classic examples:
a) Permeable layers with low resistivity.


b) “Carrot-shaped” sectioned structures, which indicate spaces with a high probability of containing water.

1b.MT GEO-WATER (ADMT)
This second device, based on the same technology, provides, in addition to visualization of the terrain structure, a set of indicators that allow identifying the zones with the highest probability of containing water.
It mainly detects sudden changes in resistivity in smaller areas, which facilitates a more precise analysis of the points where water can be found.




2. RAP (passive acoustic resonance)
This geophysical device is not based on terrestrial magnetism, but on the “noise” or frequencies emitted by the Earth and, especially, by water.
It should be taken into account that underground water —especially when it has a primary origin— is under pressure.
This pressure generates vibrations and frequencies that can be captured and associated with a certain depth.
RAP technology is the only one capable of listening to the sound of water in the subsoil. This factor is key, as the sound allows us to differentiate between a dry fault and a fault with pressurized water.
With this technology, unique in Spain, we achieve a definitive filter that allows us to guarantee up to 95% reliability of the presence of underground water on your land.
Teleradiesthesia + radiesthesia + MT Geo + MT Water + RAP = guarantee of quality underground water.

3. RG (Natural PASIVE GAMMA)
In the near future we will incorporate a new geophysical method: RG, based on the study of natural gamma radiation spectra.
The Earth naturally produces gamma rays. When these pass through areas with significant underground water, their intensity decreases. Therefore, areas where lower gamma ray emission is detected have a higher probability of containing underground water.
This method is known as the modern saurí, as it allows rapid location of areas with greater potential before carrying out detailed geophysical studies.

The last two technologies are the result of the collaboration agreement between Saurí Online and Primary Water Technologies.
