Dragons and oil in central Poland – part 2.

Hi! I hope you are doing well after Easter.

Today very short post which is continuation of a history of oil exploration in Wójcza – central Poland. I hope you liked the last week’s article describing shortly the story of this fascinating place:

Dragons and oil in central Poland – part 1.


It is very easy to locate the place of XX century oil exploration as it is located just by the main road connecting Kraków and Sandomierz (number 79). More-less in half of the way between Kraków and Sandomierz road gets closer to Vistula river and you should be able to spot couple of fish ponds. Then right after you will leave the Biechów village driving North from Kraków you have to take very sudden turn and drive on the narrow field track between two fish ponds.

Then you should try to find the Dragon’s pit on foot. Unfortunately it is not easy task. You should go into the wide sea of tall reeds. Plan which was posted in previous article might actually help you as some surface features did not change since 20’s – 30’s.

To be honest with you when I have been there for a first time I did not have any plan or map. I tried to walk into the reeds totally unprepared. Walking in the reeds suddenly I felt the smell of oil!!

I followed the oil smell and I found something which looked really interesting. That was ~2m x 2m hole filled with black, dense oil. My first thought was: I’ve found the Dragon’s pit!

Unfortunately I was not the first one as there is lot of trash around, bottles, cans and other remains after local amateurs of oil:)

Dragon’s pit?

After taking oil samples, pictures and after analysis of the map, plans and Google Earth images I had doubts if that was really the Dragon’s pit. It is possible that those are remains after pit drilled in 20’s (marked on map as 30m deep pit South from Dragon’s pit). Well, locating the real Dragon’s pit maybe should wait until another trip or someone else will make documentation on this subject before. If you are trying to locate it by yourself be careful as there might be apparently some deep pits which were not abandoned properly!

Kielce museum website

Interesting fact is that sample of oil can be found in a branch of National Museum in city of Kielce. Also there are couple of Dragon’s pit from 1965. This place looks a little different right now that is why I have doubts if this is real, original Dragon’s pit, remains of 20’s exploration works or natural oil seep.

Source of oil

Couple of vrious analyses were performed on the Wójcza oil sample to answer the most important question! From where this oil comes?

Generally measurements showed high bioderadation level which was not surprising as seep is exposed in its nature so the oil is flushed. Also its content was compared to the sample of oil taken during one of my other trips to the most famous oil seep in Slovak Carpathians (the Korna village ).

I’m not going to make you bored with lectures about oil composition and spectrometry method details but the main conclusion from the content comparison was that both oil samples are very similar! Most likely Dragon’s oil comes from Cretacous or even younger Paleogene Carpathian flysch sediments. It is not possible to describe the mechanism of migration having such limited information however maybe it is good start to solve this puzzle and help to decide if this area is commercially interesting or only very interesting natural phenomenon.

I hope you will find time to visit Dragon’s place and you liked this story!
