A method and systems for improving recovery from a hydrocarbon reservoir are described. A method includes identifying an interval within the reservoir that comprises a reduced reservoir quality, wherein the interval includes hydrocarbons. A production chamber is formed in a reservoir interval below the interval of reduced reservoir quality, wherein the production chamber is in contact with the interval of reduced reservoir quality. Hydrocarbons are mobilized in the interval of reduced reservoir quality by contact with a mobilizing agent and a pressure is changed within the interval of reduced reservoir quality to allow hydrocarbon flow from the interval of reduced reservoir quality.
