Each measurement is unique, and due to the specific characteristics of the location and wells, the duration may vary.
In general, it can be said that the examination of an average cold-water well, approximately 150 meters deep, can be completed within a day. The structural and hydrodynamic assessments together amount to approximately 4 hours.
In the case of thermal well examinations, they generally require a longer timeframe, approximately 2-3 days.
We always strive to process the collected data as quickly as possible. In the case of cold-water wells, the well inspection evaluation is completed within one week (with the exception of live drilling, where the data is provided on the same day or the next day). For large wells, this process takes approximately two weeks.
Our observers experience things firsthand in the field, and they can provide answers to the most important questions right on the spot.
Throughout the company’s history, we have encountered various types of well failures, with the most frequently occurring being false water inflow.
The causes of this can include punctured pipes, poorly sealed well casings, or pipe displacement. Another significant issue is the deterioration of water quality, which can stem from the aforementioned reasons. Additionally, other problems may arise, such as damage to filters leading to sand influx.
We also examine inserted objects, such as pumps, pump components, water level recorders, various cables, etc.
Furthermore, other issues may occur, such as inadequate water quantity, wellbore filling, obstruction of tools placed in the well, and lower temperature water flow in thermal wells.
In Hungary and all the countries we have worked in so far, we have always reached the deepest well depths and conducted measurements even under the highest temperature conditions.
Therefore, after a brief consultation, we can determine whether we can examine the well in the given case.
Apart from Hungary, we have mostly worked in Central European countries, but we have also conducted measurements in Lithuania, Cyprus, and many other places. Based on our previous experiences, we are open to carrying out measurement activities in any country.
The first and most important aspect is to have access to the wells with our survey vehicles. For this purpose, all of our vehicles are 4×4, off-road versions, and equipped with the most powerful engines.
It is important to have sufficient space around the well for both our survey vehicles and the necessary equipment.
To conduct measurements inside the well, it is generally necessary to install a pump so that we can measure with each probe. For high-yield wells or when the pump is placed deep inside the well, a crane is required for installation and removal.
On-site, we require a stable power supply to operate our equipment at both 220V and 380V voltages.
