Abstract: Methods and systems for treating a subsurface hydrocarbon formation are described herein. In some embodiments, method for treating a subsurface hydrocarbon formation is provide wherein the hydrocarbon formation comprises a kerogen containing formation that is adjacent to a formation containing liquid hydrocarbons and not having a natural recharging system, the method comprising the steps of: providing heat sources in the kerogen containing formation; energizing the heat sources to heat the kerogen containing formation; heating at least a portion of the kerogen containing formation to a temperature and for a time period sufficient to pyrolyze at least some of the kerogen; limiting production of pyrolyzed hydrocarbons so that the pyrolyzed hydrocarbons increase the pressure within the formation containing liquid hydrocarbons; and producing hydrocarbons from the formation containing liquid hydrocarbons.

Abstract: Methods and systems for treating a subsurface hydrocarbon formation are described herein. A method for treating a subsurface hydrocarbon formation includes applying electrical current to a one or more heating elements positioned in a first tubular located in an opening in the subsurface hydrocarbon formation; providing fluid through a second tubular positioned in the first tubular in the subsurface hydrocarbon formation such that a portion of the fluid flows between the first tubular and second tubular and along a length of the tubulars; allowing the fluid to flow into a hydrocarbon layer in the subsurface hydrocarbon formation; and allowing heat to transfer from at least one of the heating elements and the fluid to a portion of the hydrocarbon layer in the subsurface hydrocarbon formation.
