“…Considering the characteristics of one of the wells analysed in [34], for which its temperature and depth are similar to those of the geothermal reservoir studied in the present paper, it is estimated that the geothermal water of the aquifer is subject to a pressure of 185 bar. Knowing the temperature and pressure of the geothermal water, its density can be estimated at around 1010 kg/m 3 [35].…”

The scarcity of water resources on the island of Gran Canaria (Canary Islands, Spain) is such that 88% of the water supply for human consumption comes from seawater desalination plants. This type of process has a high specific energy consumption. Gran Canaria has an isolated electrical system of low robustness. In this paper, a geothermal plant is designed and integrated into a system that already has non-dispatchable renewable generation (wind and photovoltaic) in order to meet, based on a self-consumption regime, the energy demand of a high-capacity desalination plant. The aim is for the diversified renewable system to improve the stability and management of renewable electrical energy generation. Geothermal plant production can adapt to the energy balance between demand and non-dispatchable renewable generation. The geothermal plant’s design is based on an organic Rankine cycle and its resulting power is 4.16 MW. Its integration in the renewable generation system significantly improves the contribution of renewables in meeting the desalination plant’s energy demand and therefore reducing its dependency on the island’s electrical system. The mean cost of electrical energy generation with the diversified renewable system is 57.37 EUR/MWh, considerably lower than the mean cost of conventional generation on Gran Canaria of 153.9 EUR/MWh.

“…While simulation studies of hot water production from a geothermal source, from both geothermal aquifers and abandoned deep hydrocarbon reservoirs (Crooijmans et al, 2016;Willems et al, 2017a;Mottaghy et al, 2011;Sanner et al, 2011;Poulsen et al, 2015;Pujol et al, 2015;Tureyen et al, 2015;Daniilidis et al, 2017a;Salimzadeh et al, 2018;Macenić & Kurevija, 2018, Willems & Nick, 2019 and heavy oil are individually well studied, investigations combining the geothermal energy sources and heavy oil reservoirs are still limited. Although a few studies exist for such a combination (Wys et al, 1991;Junrong et al, 2015;Ziabakhsh-Ganji et al 2018), the integration of geothermal hot water production with EOR from a heavy oil reservoir with a horizontal well doublet has -to our knowledge…”

Geothermal projects, as renewable energy projects, are not economically attractive in most places of the world at the current state of development; for this reason, subsidies are required by energy and environmental authorities in order to increase the interest in such projects. In this paper, we assess and model strategies for integration of geothermal energy with oil productions of the Moerkapelle oil field in the Netherlands. To do so, numerical simulations have been employed to analyse the feasibility of a fluvial oil reservoir for the synergy potential of oil and geothermal energy exploitation. In order to implement the simulation studies, single phase and two-phase non-isothermal fluid flow modelling are utilised for the geothermal well doublet system and for water flooding in an oil reservoir (including facies heterogeneity), respectively. A series of simulations have been conducted to investigate how hot water from a geothermal reservoir beneath a heavy oil reservoir in the fluvial sedimentary system of the West Netherlands Basin can be used for Thermal Enhanced Oil Recovery (TEOR) and geothermal energy production.This study finds that the high degree of heterogeneity in fluvial oil reservoirs could significantly affect oil recovery improvement and hence the synergy strategy. High values of a) Net to gross (N/G) b) Bottom Hole Pressure (BHP) and c) horizontal wellbore length are favourable for oil recovery. In contrast, wide horizontal wellbore spacing and oil viscosity have an adverse effect on oil recovery enhancement. Furthermore, the results display that the enhanced oil production helps to reduce the required subsidy for a single doublet geothermal project up to 100 %. Consequently, the extra amount of oil produced by utilising the geothermal energy, could make the geothermal business case independent and profitable.
