Systems and methods for utilizing fluid produced from a geothermal source to generate electrical power and provide energy for upstream oil processing as part of a binary power generation station. Use of the geothermally-heated fluid continues in an enhanced oil recovery operation. Thermal energy of the geothermally-heated fluid heats a working fluid of a binary power generation plant to operate a turbine and to heat an oil heating medium as part of a gas-oil separation plant. The enhanced oil recovery operation may be a waterflooding operation.
