Multi-lateral well construction by directional steel shot drilling: Optimisation of the (mechanical) specific energy utilisation
conference paper
Energy provision from the subsurface plays a key role to achieve the climate goals as outlined in the European Green Deal. Given that more than 50% of the energy demand in Europe is based on the (seasonal) requirement for heat, geothermal energy from shallow to mid-depth resources has the potential to deliver a substantial share of this heat demand and contribute to the climate goals. A high degree of uncertainty caused by unknown or limited understanding of the reservoir quality leads to a considerable risk for investors and geothermal operators. The construction of multi-lateral wells is a well-known tool in the oil & gas industry to overcome challenges of reservoir heterogeneity and/or enhance productivity by increasing the reservoir contact, connecting compartmentalised zones and intersecting pre-existing fracture sets. The potential impact of multi-laterals for geothermal sites has been mapped in various studies (i.e., Peters et al., 2018, Lentsch et al., 2020).
