Abstract
The Szolnok Oil Field in central Hungary – discovered in 1953 (Thamó-Bozsó, 2018) – was in continuous production until its final abandonment in the 1990s. The gross of the producer and appraisal wells were drilled between 1954-1958 and were measured with an obsolete “Eastern-European-type” of open hole logging suite. Historically these log curves were found to be essentially useful in delineating permeable layers, correlating sand-prone beds, stratigraphic well tops and distinguishing hydrocarbon from water-bearing zones. However, their application was rather limited for a quantitative characterization of any petrophysical properties (e.g., clay volume, porosity, water saturation), which are routinely obtainable from a modern open hole log set.
