Abstract:
A method includes pumping an agent in a well across a target formation zone with rocks containing soluble salt cement. The agent is injected into pore space within the target formation zone extending a radial distance from the well using pressure, and the agent is allowed to cure in the pore space. The method further includes taking a core of the target formation zone containing the cured agent.
