3D CT scan image analysis of wormholes

Cylindrical carbonate specimens of approximately 65-70 mm length and 25 mm diameter were treated with chemical stimulants, an acid and a biodegradable, non-hazardous liquid. Our task was to carry out CT scanning and to construct 3D models of both the plugs. The aim was to visualize the pathways and interconnected pore space (or “wormholes”) which both the agents created in the limestone. Our 3D reconstruction revealed that the acid dissolves much more carbonate rock and forms a much broader channel than the biogradable liquid. However, the fine network of wormholes created by this liquid is much more suitable as a pathway for hydrocarbons and consequently, the non-hazardous liquid serves as the more appropriate stimulant compared to the acid.
