Abstract

Water is removed from passages in a subterranean hydrocarbon formation by feeding into the passages a composition comprising 5 to 70 wt. % of alkanol(s) having 1 to 3 carbon atoms and 30 to 95 wt. % dense phase carbon dioxide, under a pressure greater than zero up to 25,000 psig and at a temperature of 0°F to 200°F, allowing the feed composition to remain in the well, whereby the feed composition solubilizes with said water in said passages, and then removing from said well a liquid product composition comprising said solubilized water and alkanol.
