  Today, the term 'productive horizon' is widely used in the practice of geological exploration. There are two fundamentally different approaches to the interpretation of this term. According to the first, it means a certain part of a geological section, which is identified using geological research methods to determine the place in the geohistorical chronicle of the investigated region and the position on stratigraphic diagrams, and accordingly, can be considered as a certain stratigraphic unit ('tratigraphic term'). According to another interpretation, the productive horizon characterizes the strata of rocks productive for hydrocarbons from the position of oil and gas geology, i.e. a reservoir, a cap, a fluid. This term refers only to an oil and gas-saturated reservoir in a field, its meaning as one of the components of a hydrocarbon system and no stratigraphic content – 'reservoir term'. The practice of conducting geological exploration works both in Ukraine and abroad (mainly in the countries of the former USSR) shows that the term 'productive horizon' in its content is a stratigraphic unit, that is, a stratigraphic subdivision. Since, in the current edition of the Stratigraphic Code of Ukraine, there is no information on the stratigraphic division of hydrocarbon-productive deposits of oil and gas-bearing regions of Ukraine. This publication aims to draw the attention of the geological community to the objective reality of the long-term existence of oil and gas stratigraphy and the integration of its terminological base into the Stratigraphic Code of Ukraine by developing appropriate subdivisions that would reflect the features of division, correlation and indexation of hydrocarbon-bearing strata.
