The excitement of drilling oil wells in the Eastern Black Sea region

SHAFAQNA Türkiye – Minister of Energy and Natural Resources Fatih Donmez said in a television program he attended on May 21 regarding oil and natural gas exploration activities in the Black Sea: “We will also carry out our exploration drilling in new fields. We have completed our seismic survey at Ordu. At the final stage, we will go to the Eastern Black Sea region. We can find oil there. We will have one more drilling offshore Trabzon-Rize. From west to east, every place where potential is visible will be used,” he said.


Kemal Akdag, a former lecturer at the Faculty of Geological Engineering of KTU, said that oil reserves accumulate in certain regions according to the structure of rocks, and said: “They are formed as a result of the transformation of organic matter in sediments deposited in the sea into oil feedstock, called “kerogen”. Its raw materials are living beings. “Kerogen” is formed as a result of the accumulation of sediments along with these living things over time and burial with new sediments on them and changes under certain conditions of temperature and pressure. It is important whether there is a substance that will form “kerogen” in the Black Sea sediments.

If they are present, an oil is formed. Existing leaks in the Black Sea, such as the live oil spill off the coast of Chayeli, means that the leaks come from somewhere in the sediments in the Black Sea. Readings in the Black Sea indicate the presence of oil. At sea, these signs are important. But its source may not be where it came from. Because the oil migrates. It is not where it is formed, but where it is closed,” he said.


Saying that intensive exploration work is needed to find oil in the Black Sea, Akdag said: “Oil usually forms in marine rocks and environments. I cannot say that the Black Sea is rich. We do not know the distribution of sediments containing oil in the Black Sea. Only at the end of seismic exploration, where promising areas are located, they need to be determined.

Upon completion of seismic exploration, drilling and then operational work begin. Once these areas are identified, drilling operations should be directed to these areas. If you drill 10 wells and find oil in 1 well, it becomes profitable. It cannot be stopped until 1-2 wells are drilled and mothballed. After hundreds and thousands of drillings, it can only work in one region.”


Stating that the size of the area of ​​oil reserves is important, Akdag said: “Seismic surveys are carried out to extract the crust, then drilling in the structures determined by the seismic surveys performs the necessary operations to extract oil. If oil is found in any drilling, that field will be expanded. Of great importance is the structure and size of the oil reservoir. In the Black Sea, rocks containing these oils are found in rocks of a certain age range.

There are many sedimentary rocks deposited in different periods of geological time. Each of them may contain oil. If there is bedrock in these deposits, if it has produced oil under the right conditions, it will wait until it is preserved and protected, and we are looking for it.”


Akdag said that if oil is discovered in the eastern part of the Black Sea region, it will bring significant benefits to the economy: “The discovery of encouraging deposits and oil at the end of exploration will, of course, make a big contribution to the economy. Oil is an important resource today. In this regard, it is an important underground wealth. It is extremely important to find him,” he said.
