Abstract
A production method for low permeability formations is disclosed. Short steam cycles followed by production of fluids to the surface from a single wellbore is described. The method may be practiced in sequential manner, thereby accessing multiple intervals of hydrogen containing formation. Reflashing of steam into the wellbore allows production of fluids to the surface without a pump in the wellbore.
