Elevated temperature effects on swelling pressure of compacted bentonite
Deep Underground Science and Engineering, EarlyView.We present a set of new experimental investigations on the effects of elevated temperature on the swelling pressure development of compacted bentonite. This research was motivated by an emerging interest in using bentonite as a plug material in oil and gas well abandonment.
