Through our "Big-Data" analytics approach to Reservoir Confirmation, we're bringing Geothermal Power to more locations around the world.

TEP Geothermal Advantage
the power of big-data & Predictive analytics
By analyzing large amounts of information – (both structured and unstructured), very quickly, TEP provides a streamlined development approach to geothermal projects with a more accurate course of action.
Prior to TEP’s approach, data has been scattered across silos (in and out) of the industry. Projects often deal with ineffective coordination of information and lack of a clear business case for deployment. TEP’s Big Data approach brings more information together to solve complex problems with greater speed & accuracy.
Enhanced Insight & Process Automation. From resource assessment, to well field development, to investment decision to electricity production, we're leveraging more accurate forms of information processing that enable enhanced insight, decision-making, and process automation. The result better business decisions for the development of geothermal resources to deliver more reliable and stable power.

Accuracy Matters. Our Big-Data analytics has been applied to the traditional "hot-spot" geothermal approach resulting in greater precision to produce baseload renewable electricity. When TEP's data-driven approach is applied to deep sedimentary basins, it has resulted in an ever-expanding map of the earth's interior fluid that is much more widely available than previously thought, thus bringing the possibility of geothermal electricity to more locations around the world with lower risk and greater accuracy.

GEOTHERMAL METHODS
In its simplest form, geothermal energy is the process by which the energy used to drive turbines is produced by heat from the earth, rather than through burning of fossil fuels. No combustion takes place in this process and there is no cost for “fuel” used to drive the turbines, other than the expenditures necessary to tap the heat source. The result is power without the production of combustion-related carbon dioxide at a lower cost than other forms of electricity.
Of all the types of renewable energy, geothermal comes with a small footprint, available 24x7 and produces zero emissions.
There are several different types of geothermal energy approaches today. For example:
Traditional or Conventional Hydrothermal: have common ingredients of water and heat. These geothermal reservoirs of steam or hot water occur naturally where magma comes close enough to the surface to heat groundwater trapped in fractured or porous rocks, or where water circulates at great depth along faults. Dry steam (vapor) reservoirs and hot water (liquid) reservoirs are used to generate electricity.
Sedimentary & Geopressured: Geopressured gas has been developed to produce geothermal electricity and these resources are found in Sedimentary & Geopressured Systems. This approach is described as the utilization of kinetic energy, hydrothermal energy, and energy produced from the associated gas resulting from permeable layers at depths (typically between 2-5 km).
Enhanced Geothermal Systems (EGS): or hot dry rock systems are located where hot masses of low permeability rocks are found at drillable depths.

Our Approach to Projects
Resource Definition
Our unique resource definition method is not focused on conventional heat from geographically limited hot springs or geyser locations, but instead, it is derived from hot fluids within permeable sediments found (world-wide) where the natural heat flow from Earth’s interior has heated these in situ fluids to temperatures above 225 degrees F.
Technology Advancements
Advancements in drilling and heat-to-energy conversion technologies have made the production of electricity from deep source geothermal economically possible. These advancements grew out of the petroleum industry’s revolution in horizontal drilling and formation improvement methodologies that significantly reduced the cost of deep well drilling and renovation of deep wells for thermal energy production.
Efficiencies in Production
Because of the high cost associated with operating and maintaining deep wells, it simply was not cost competitive for geothermal energy to be produced from deep, hot formations. However, new drilling technology and substantial improvements in the conversation of thermal energy to electrical energy using binary heat exchange systems have made the generation of electrical energy practical and profitable.
