Abstract
A method for intermittent steam injection which comprises completing wells in more than one zone and selecting a number of wells as steam injectors. As interwell communication (temperature breakthrough) develops, producers are shut-in to allow for the reservoir pressure to build up and heat to propagate from the channel of communication (e.g., fractures) to the reservoir matrix. The injection phase is followed by blowdown. Thereafter, shut in producers and, in certain other cases, injectors are put on production.
