Abstract: A power production process integrates geothermal steam and fossil fuel energy sources to give a higher energy efficiency than is normally obtained when using these energy sources individually. Geothermal steam is partially diverted from a steam turbine and injected into a combustion turbine. Although the steam turbine output is reduced by the diversion of steam, the plant efficiency and total plant output are improved.

Abstract: A method and apparatus for eliminating the static venting of shut-in geothermal wells producing from vapor-dominated geothermal formations comprising providing a closed system means for interwell flow of geothermal vapors from higher pressured wells to lower pressured wells so that the flow of geothermal vapors between the wells interconnected by said flow prevents accumulation of condensate and non-condensable vapors in said wellbores. Usually between 2 and about 15 completed geothermal wellbores in the same formation are connected in interwell flow.
