This document provides an overview of GeoTek Energy's ThermalDrive technology, which is a geothermal-based motor that replaces electric motors to power submersible pumps. The technology uses a working fluid circulating through a thermo-syphon loop to transfer heat from produced fluids downhole, powering a turbine called the ThermalDrive which drives the pump. Computer modeling and multiple patents have been obtained, and the technology is currently in prototype testing with support from the Department of Energy and engineering partners.

The earlier part of the course (Fundamentals of Operation and Troubleshooting of Emergency/Standby Power Generation using Diesel Generators IDC workshop) covered the fundamental principles of the diesel engine-generator set. This part will discuss the need for standby/emergency power generation in industries and the details of engine-based power stations. Achieving large standby capacities would call for multiple generating sets to be operated in parallel and at times synchronised with an external power source. The factors to be considered to achieve proper load sharing and also to safeguard against power grid abnormalities are discussed. A brief description of the engine-based uninterrupted power source is also included.
turbine from the Latin turbo, a vortex, related to the Greek meaning "turbulence is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.[3] A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels.
With the development of technologies such as VVT (Variable Valve Timing) and VVL (Variable Valve lift) controlled by ECU resulted in the development of modern ivtec, multiair and other advance engines which not only improved performance but also were energy efficient with less NOx emissions.
Design, Modeling & Analysis of Pelton Wheel Turbine BladeIJSRD
A Pelton-wheel impulse turbine is a hydro mechanical energy conversion device which converts gravitational energy of elevated water into mechanical work. This mechanical work is converted into electrical energy by means of running an electrical generator. The Pelton turbine was performed in high head and low water flow, in establishment of micro-hydroelectric power plant, due to its simple construction and ease of manufacturing. To obtain a Pelton hydraulic turbine with maximum efficiency during various operating conditions, the turbine parameters must be included in the design procedure. Here all design parameters were calculated at maximum efficiency by using MATLAB SOFTWARE. These parameters included turbine power, turbine torque, runner diameter, runner length, runner speed, bucket dimensions, number of buckets, nozzle dimension and turbine specific speed. The main focus was to design a Pelton Turbine bucket and check its suitability for the the pelton turbine. The literature on Pelton turbine design available is scarce; this work exposes the theoretical and experimental aspects in the design and analysis of a Pelton wheel bucket, and hence the designing of Pelton wheel bucket using the standard rules. The bucket is designed for maximum efficiency. The bucket modelling and analysis was done by using SOLIDWORKS 2015. The material used in the manufacture of pelton wheel buckets is studied in detail and these properties are used for analysis. The bucket geometry is analysed by considering the force and also by considering the pressure exerted on different points of the bucket. The bucket was analysed for the static case and the results of Vonmises stress, Static displacement and Factor of safety are obtained.
This presentation was given at the end of the Spring 2016 semester for the class at Georgia Tech AE 4802 Digital Design and Manufacturing. The presentation encompassed the Hyperloop concept and built upon preliminary analysis done by the GT Hyperloop Team

3. GEOTEK’S BUSINESS
APPLYING RENEWABLE TECHNOLOGY TO HYDROCARBON PRODUCTION
• GeoTek is finalizing development of a unique, highly efficient
geothermal-based technology, called ThermalDriveTM
• ThermalDriveTM is a motor driven by thermal energy and replaces an
electric motor that powers a submersible pump system
• Primarily focused on sales/licensing within the oil & gas (O&G) industry
serving on shore and offshore applications
• Secondary focus on sales /licensing within geothermal power industry,
especially EGS

4. GEOTEK’S TECHNOLOGY APPROACH
• Based on the thermodynamic cycle and performing work as defined by the Carnot cycle, GeoTek’s
patented and patent pending technology is an innovative application of the geothermal binary cycle
(Organic Rankin Cycle) which uses a working fluid to change heat to energy to work.
• Derived from GeoTek’s patented gravity head energy system (GHES), it is a geothermal production
technology that minimizes or eliminates parasitic loads (& electric costs) associated with pumping of
production wells and the secondary working fluid (also eliminates problematic electrical components)
• The technology includes three GeoTek innovations: a gravity driven thermo-syphon loop for the
working fluid; a downhole expander / pump system to perform work; and, performance evaluation /
well design software
• GeoTek’s thermo-syphon loop relies on gravity to circulate the working fluid (as it gains heat [energy]
from the produced fluid) from the surface equipment to the downhole pump without the use of
electrically driven pumps
• GeoTek’s system uses energy from the working fluid to power the expander, called ThermalDriveTM,
which drives the pump and moves the well’s produced fluid. This also eliminates the need for an
electric driven pump

5. TECHNOLOGY BASICS
CARNOT ENGINE – HEAT TO WORK
• To pump fluid from a well using geothermal energy
requires a heat engine – a mechanism that changes
heat (energy) to work.
• Geotek’s thermal motor, the ThermalDrive, is a
Carnot (heat) engine
• A working fluid, following the Carnot cycle shown to
the right, gains heat from the produced fluid as it
travels down into the well
• Arriving at the ThermalDrive as a supercritical fluid, it
enters, expanding into a lighter vapor and giving up
the heat (energy) during expansion which drives the
pump
• From the ThermalDrive, the vapor now travels up the
well, enters the condenser on the surface, is cooled
to become a liquid, and thenn repeats the cycle

6. TECHNOLOGY BASICS
THERMO-SYPHON LOOP
• To power standard surface generators, geothermal binary systems use
a refrigerant (working fluid or WF), that is typically moved through the
closed loop system by electric pumps
• In the GeoTek system, during the descent down the well, the working
fluid WF (dark blue) increases in pressure due to gravity and head.
• After passing through the crossover, the WF now under high pressure
flows downward around the produced fluid tubing (center-pink) where
it is heated by the produced fluid being pumped to the surface by the
ThermalDrive pumping unit
• The energy to drive the GeoTek system for power generation or
pumping is derived from the heat in produced fluid (center-pink) that
has been transferred to the WF (lite blue) as it is drawn further down
the well by gravity
• The WF converts into a supercritical fluid as it enters and drives the the
ThermalDrive pump system, pumping the produced fluid to the surface.
Exiting the ThermalDrive as a lighter vapor, the WF travels back to the
surface where it is condensed to a (heavier) liquid which is then again
driven by gravity downward, repeating the loop.

7. CORE TECHNOLOGY
THYMOTM – THE COMPUTER MODEL
• To ensure the ThermalDrive pump system can reach
its critical efficiency, pump fluid and also generate
power, computer modeling of the well is required
• GeoTek partner, Blade Energy Partners, Frisco, TX,
developed a thermal assurance model that would
utilize more than 50 well variables
• Using Blade’s Thermal Assurance model, Ortloff
Engineers LTD, of Midland, TX, developed a more
rigorous and effective computer model that
accounted for additional design and downhole
operating variables – the model is now called THYMO
• THYMO now does well performance evaluations and
designs with more productivity and accuracy

8. CORE TECHNOLOGY
THE ThermalDrive
• In GeoTek systems, the turbine component of the
pumping system, called ThermalDriveTM , acts as a
Carnot cycle heat engine.
• Entering the turbine, the super critical working
fluid (wf) expands into a vapor converting heat to
work
• The ThermalDrive, as a heat engine, is a turbine
operating on the same gas expansion principle as a
steam turbine
• The typical turbine uses a simple turbine blade as
shown to the right
• The ThermalDrive, driven by the working fluid, is
coupled to a pump which then pumps the
produced fluid, brine or an oil/water mixture, to
the surface.

9. CORE TECHNOLOGY
ThermalDriveTM Pumping System
• The ThermalDrive or turbine is magnetically coupled to the
pump as shown to the right
• Unlike the turbine blade on page 9, GeoTek’s ThermalDrive,
shown below left, is mounted circumferentially around and
outside the production tubing
• The ThermalDrive is magnetically coupled through non-
ferrous tubing to the pump shaft shown below right
