Another challenge is the presence of natural fractures and cavities within the limestone. These can lead to instability during drilling, potentially causing borehole collapse or drilling deviation. To address this, engineers use techniques like underreaming or casing to reinforce the hole and maintain stability. Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planningdrilling through limestone.
