 abstract={Improvement of life quality, food production and sustainability requires search for better, efficient natural resources extracting methods, while minimizing environmental impact, which is determined by carbon and water footprint calculation. In order to counter global phenomena, it is necessary for food-producing chain to work together to take conscious action on environment. Restoring balance demands action to reduce greenhouse gas emissions and rational water use, by reducing energy intensive processes or increasing efficiency of wastewater treatment methods. This requires a thorough understanding of all phenomena that determine a given process. Viscous fingering occurs during such processes as enhanced oil recovery, metal crystallization in batteries, sugar refining, groundwater purification and many others. Research to improve knowledge of this phenomenon and ability to predict its effects is crucial in development of basic industrial processes. This paper presents an experimental study of tracking immiscible viscous fingering in modified Hele-Shaw cells filled with a granular bed of known parameters. The influence of bed parameters and flow conditions on the observed phenomenon was investigated. During the tests, beds with the following grain diameter ranges were used: 200–300, 300–400 and 400–600 μm; the liquid was injected at three different flow rates in the range of 100–400 ml/h. On the basis of carried out work, a model of the studied phenomenon was proposed, which made it possible to determine the extent and the fingering scale.},
