We want to see the asphaltene deposition in the reservoir rock sample by imaging method, before and after the treatment. at first, we should capture the image of the asphaltene depositions in the mini-plug of rock, and for the other step (the treatment), we need to analyze the same rock sample by imaging. but in this way, we can't use the previous mini-plug of the reservoir rock for treatment. What is your suggestion and idea about this challenge? thanks
