This project focuses on developing methods for detection and mitigation of risks while drilling in karstified carbonates. Drilling into a karst-like object can lead to losses of drilling fluid into the formation, including the most severe case of lost circulation. Detecting regions with high risks of karst-like objects or even predicting such objects in proximity of the drilling bit has a significant value for drilling safety. The project seeks such detection methods either based on available drilling data or based on novel measurement tools.
