... of bio-based and biodegradable chelating agents and seawater. The approach involves injecting an acidic chelating agent solution to increase the effective porosity and permeability through chelating-agent-driven enhanced mineral dissolution. After that, alkaline GLDA-containing seawater is used...

... aqueous solutions of environmentally friendly chelating agents (GLDA and HEDTA) at pH 4. As a result, it has been observed that the rock permeability increases quickly and significantly and the expected selective mineral dissolution creates voids within the rock. The present study has demonstrated...
