https://doi.org/10.3997/2214-4609.202121029
Highlights
- Geothermal energy in place in the Mangyshlak Basin: about 70,000 EJ.
- Prospective potential: up to 1,500 EJ, with heat extracted down to 7 km and 2% recoverability.
- Triassic reservoir intervals: above 150 °C at 3–4 km depth.
- Data: reservoir temperatures and bottomhole temperatures of oil and gas wells.
Summary
Ashirgul Kozhagulova, Milovan Fustic and colleagues make a preliminary assessment of the geothermal energy potential of the Mangyshlak sedimentary basin in western Kazakhstan. They use data from the oil and gas industry: reservoir temperatures and the bottomhole temperatures of drilled wells.
Depth–temperature profiles show that Triassic units are the most promising for geothermal energy production. The authors calculate the geothermal energy in place, as the heat released by cooling the rock by a given temperature difference, at about 70,000 EJ. Extracting heat from the rock down to 7 km, with 2% of the resource recoverable, would give a prospective potential of up to 1,500 EJ. High-quality reservoir intervals in the Triassic are hotter than 150 °C at 3–4 km, which the authors consider enough for direct electricity generation. Regional temperature maps of the basin followed in Kozhagulova et al. (2023).
