One of the most defining long-term projects in our company history was the exploration of the Boda Aleurolite Formation (BAF).
The latest field surveys spanned more than a year between October 2020 and the fall of 2021. As before, during the previous exploration cycles, once again our company performed all of the logging surveys in the three core drillings in development back then.
These included complex geophysical well-logging, acoustic BHTV surveys, flowmeter surveys, VSP, NMR surveys and downhole water sampling.
For the first time during the entirety of the project we managed to perform pre-planned NMR surveys for research purposes instead of testing or trial. The thoroughness of this research project is also indicated by the fact that our company was tasked to perform almost all geophysical well-logging services we possibly could at the time.
During the project, we not only collected a lot of valuable data about the BAF, but also improved ourselves in the application of geophysical methods.
The BHTV surveys gave us a detailed picture of the rock fracturing and structure, which provided important information about the hydrogeological conditions.
The VSP surveys refined the seismic data and determined the velocity and elasticity of the rocks.
The NMR surveys opened up new possibilities for determining the porosity and water content of the rocks.
One of the biggest challenges of the project was that the core drillings were done at great depths and in oblique directions, which made it difficult to lower and pull up the instruments. In addition, the environmental conditions were variable, so we had to adapt to the weather and terrain.
During the project, we faced several technical difficulties, such as instrument failures or data loss, but we managed to solve them all successfully.
At the end of the project, we proudly handed over our report to the client, who were very satisfied with the results. The exploration of the BAF contributed to a better understanding of Hungary’s geological background and mineral resources.
We hope to participate in many more similar projects in the future!
