Innovating & Aggregating
GenaSysTM technology accesses geologic formations – known as hot sedimentary basins – to harvest their geothermal energy. This resource is…
Timing is everything.
As little as 10 years ago, the technologies needed to economically harvest geothermal power were simply not mature enough. But these technologies have been advancing rapidly in recent years. The technologies that Geothermal Technologies will leverage in its innovative approach to harvesting geothermal energy are now ready to support our unique approach. Today, when the need for renewable energy is critical, Geothermal Technologies is poised to deliver it.
Precision Drilling Technologies
All of the activity in the oil & gas sector in recent years (Marcellus, Bakken, Prudhoe Bay, Permian Basin, etc.) has resulted in wholesale improvements in drilling techniques and economics. Oil companies commonly have to drill three-dimensional wells extending over several kilometers to reach new reservoirs. In addition, precise steering control is required during drilling to maximize reservoir contact and to avoid hitting existing wells. Today’s drilling precision is incredible. This same precision will be leveraged by Geothermal Technologies in drilling our geothermal wells.
Advanced Subsurface Monitoring Technologies
Like drilling, rapid advancements in monitoring technologies such as 3D active and passive seismic imaging, electromagnetic geophysical imaging, and downhole fiber optics will allow GTI to collect, process, and analyze data to identify activity in the subsurface related to active fractures and active fluid volumes and to measure temperatures, pressures, and fluid flow in real time. The identification of active fractures and volumes will facilitate the accurate targeting of new injection and production wells as well as the optimal placement and spacing of horizontal wellbores.
Recent advances in Cloud computing have allowed GTI to extensively forward model various configurations of our power systems in a cost-effective and timely manner. Incorporating extensive site-specific geologic data into newly developed third-party software, we are able to characterize, analyze, and understand the complex fractured rock systems at our target locations. We then integrate this data into our own proprietary models to accurately simulate subsurface fluid and heat flows. With these simulations we can design our systems to provide for optimum heat extraction and convective system recharge. Our patented methodology will enable the creation of bespoke systems that can operate for decades.
Machine Learning / Data Fusion
Numerous relevant data layers are incorporated into our methodology of identifying the optimal locations for our GTI power systems. These can include subsurface data such as information from well logs and core analysis, airborne geophysical data, the analysis of 3D seismic data (to better understand the structure of the basin and attribute analysis), and data from other techniques used to capture the in-situ permeability of the rock and potential fracture systems. These data layers can also include surface information related to electrical infrastructure, oil and gas operations, land ownership, regulatory information, etc. GTI is developing data driven models to quantitatively fuse the relevant surface and subsurface information. These models will be applied to obtain maps describing and ranking the relative suitability of targeted locations for Geothermal Technologies’ power generation facilities.
Electrical Power Generation
Organic Rankine Cycle (ORC) systems are used for power production from low to medium temperature heat sources, such as geothermal. Recent technological advances in ORC design are enabling lower input temperatures and higher operating efficiencies than previous designs. Today’s binary geothermal power plants feature multi-pressure-level cycle systems. This cycle configuration offers a significant increase in power output and in cycle efficiency. Advanced ORC’s can now efficiently operate in the range of 80 to 350 °C, thereby expanding the geographical reach of economic geothermal power.
Geothermal Technologies Connects the Dots
By aggregating and leveraging the advancements in all of the above technologies, and integrating them with our own innovations, Geothermal Technologies has engineered a sophisticated process that will revolutionize the geothermal and energy industries. With the environment in mind, we have developed a novel system that will deliver sustainable renewable energy for a greener world.
