Abstract

Collection and analysis of well data is important process, allowing a reconstruction of the penetrated rocks. Numerous charts and diagrams illustrate all sorts of geological information. Some of them are demonstrated and generalized by well sections from south-western part of the Central North Bulgaria. Logs together with well core and cuttings are the bases for construction of a general Mesozoic lithostratigraphy column. Besides the major lithotypes the source rocks, reservoirs and seals are also outlined. Selected Triassic rocks from well sections with increased presence of organic matter are characterized by so called “geochemical logs”. They show the kerogen richness and maturity in depth. 1-D modeling of the subsidence and thermal maturity reconstruction show oil and gas windows for well R-1 Kalenik. Complex data analyses can also reproduce the hydrocarbon generation from the perspective Middle Jurassic source rocks (Stefanetz member of Etropole Formation).
