A production well is provided in the subsurface reservoir 2. A heat treatment 7 is performed on a region of the subsurface reservoir and/or a region adjacent to the subsurface reservoir. Hydrocarbons are then produced via the production well 3. The heat treatment may induce thermal fractures, increase the mobility of fluid hydrocarbons, and pyrolyze kerogen to generate recoverable fluid hydrocarbons. Thermal fracturing may be used to increase the size of existing hydraulic fractures in the reservoir. The reservoir may be an oil shale or tight oil reservoir. The heat treatment temperature may be in the range 250 °C to 450 °C. Heat may be provided by a pipe with circulating hot fluid, an electric heater, a radio waves, microwaves, induction, or hot fluid injection and there may be two stages of heating. |
