PRODUCTION OF GEOTHERMAL ENERGY
Geothermal systems based on engineering solutions without water production, the so-called EGS (Enhanced Geothermal Systems) are becoming more and more common worldwide, allowing the use of thermally heated rocks as a heating source without the extraction of water. The medium is supplied to the system from the outside through engineering solutions, thus creating a closed loop system. The EG systems cover a wide spectrum of power (MW-kW). The WeHEAT technology is a DEEP geothermal probe operated in a fully closed loop system, implemented in the wellbore structure of deep dry holes. Implementation which does not require drilling and which includes a special internal heat insulation makes the system very cost-effective, as compared with other geothermal systems. The key to successful installation of WeHEAT systems is the proper well construction and the correct design. Proper design takes into account the geological settings , establishes the energy calculation with a heat transport model, and then the design of the surface facilities is added.
As a result of this development, companies engaged in O&G and geothermal energy in the areas of the hydrocarbon industry and geothermal energy use will have the possibility to decrease the costs related to depleted wells and give a new function to deep drillings through minor modification.
Furthermore, companies in the vicinity of the well may consider the old facilities, often “being in the way”, as a cheap, clean, and stable source of energy.
With the WeHEAT SYSTEMS, you can choose a new heat production method that can primarily be used for the heating of large buildings with a high energy demand, where heat production is an environmentally friendly, Co2 emission-free green energy, replacing fossil fuel heating.
