Abstract
Although oil production has a long history in Romania, the offshore discoveries from the Western part of the Black Sea are still relatively newly developed and with further potential to be revealed. To find the best places for new wells, as well as making new oil field discoveries, it is very important to understand the petroleum system of the area. If the elements of the petroleum system are well understood, then the potential of the Black Sea will become bigger, as the complexity of the area will be acknowledged. Two major petroleum systems were discovered in the area, the thermogenic system, and the biogenic system. The thermogenic system is corresponding to the shallow area of the Black Sea, where current productive fields are, while the biogenic system is corresponding to the deeper area, currently being in the exploration stage. The purpose of this article is to present both petroleum systems from the Black Sea Romania, their elements, the evolution they had, and the major differences between the two.
Highlights
With the growth of demand on the oil market, the big companies started to search for additional resources and to develop new technologies for oil extraction
This paper presents the general geological settings of the Western Black Sea Basin, from the stratigraphic and tectonic points of view, the elements and definition of the petroleum systems in general, and the two main petroleum systems from the studied area, the thermogenic system and the biogenic system
Mixed traps- formed by the combination of tectonic and stratigraphic elements When discussing petroleum system evolution, the first process is represented by the generation of hydrocarbons, a process that depends on the transformation suffered by the organic matter from the source rock
Summary
With the growth of demand on the oil market, the big companies started to search for additional resources and to develop new technologies for oil extraction. Romania is a country with rich oil history, starting in the middle of XIX century till today, having the first commercial well drilled close to Moinesti. Even though the oil industry started to develop in Romania quite early, the first discovery done in the Black Sea basin from offshore Romania was done in 1978. The Western basin of Black Sea is split into two main areas, the shallow water area and the deep watter zone. The shallow water area it is better understood and developed, having fields. This paper presents the general geological settings of the Western Black Sea Basin, from the stratigraphic and tectonic points of view, the elements and definition of the petroleum systems in general, and the two main petroleum systems from the studied area, the thermogenic system and the biogenic system
