Abstract
There are two important territories in Slovakia with functioning gas well operations: the Eastern Slovak Lowland and the Vienna Basin. This article focuses on the creation of electronic monitoring and graphical mapping of the current technical conditions of gas wells in the Eastern Slovak Lowland. An analysis of the gas wells’ current state in the terrain is available. The aim of the article is to draw attention to the current state of gas wells, such as the insufficient processing of gas wells, the lack of summary and uniform records concerning them, and the lack of an electronic system for monitoring the technical security of the wells. The scientific contribution of this article lies in its ability to interpret and address operational problems related to gas wells. Through analogy, the step algorithm expresses the possibility of also using gas wells for oil, geothermal and hydrogeological wells. The intention was to highlight the importance of the need to create a database for the security and strategic needs of the state regarding the storage of natural gas. As of yet, no computer or graphic system has been used in Slovakia to monitor, unify and clarify the actual technical condition of gas wells. Using the ArcGIS electronic and graphical software tool, the mapping and recording of gas wells was carried out in the area under investigation. The mapping was completed with the mentioned technical patterns. These patterns have the information found on individual gas wells. After the information is added to the database, this mapping can also be carried out in another important area with functioning gas wells, such as in the Vienna Basin, which could be another theme for further research in this area.
Highlights
Today, Slovakia is almost entirely dependent on the import of oil and natural gas
As we have demonstrated in the introduction, up until recently, information on the location and condition of historical oil and gas wells in Slovakia has been poorly recorded and archived, including important geological, fluid and hydrocarbon production information collected for each well
We considered all gas and oil wells in Slovakia, which are registered by NAFTA Ltd. (270 wells)
Summary
The history of oil production in Slovakia, which was previously part of Austria-Hungary and later Czechoslovakia, is one of the oldest in the world, and its origins date back roughly to the middle of the 19th century. Extraction from a geological point of view was situated in the area of the western and eastern part of the flysch belt of Slovakia. Extraction in these territories declined, and in the period between the First and Second World Wars, almost completely disappeared. During the First World War, intensive exploration and extraction began in the Vienna Basin area, and in the 1960s in the East Slovak. These extraction locations reached their maximum production in the 1960s and 1980s
