ABSTRACT 
The production of heat and electricity from geothermal energy is an old concept and has been around since the early 1900’s.  However, many geothermal projects are plagued by high up-front exploration costs and have financing difficulty because of the geological risk, namely low permeability, and many do not make it past the exploration phase.  To solve these issues technologies such as hydro shearing and production from hot dry rocks are pursued.  Historically geothermal energy is produced from high capacity aquifers. Recently the concept of production from enhanced geothermal systems through hydro shearing tighter aquifers or production from hot dry rock is growing in popularity. Hydro-shearing is often met with uncertainty by local stakeholders because it is perceived as fracking on the scale of that of the oil industry. Drilling into hot dry rock involves drilling deep and costly wells into plutonic rocks and has, in some instances, caused induced seismicity. 

The concept of producing geothermal energy from true multilateral closed loop systems, whereby there is zero interaction with the formation seeks to solve the problem of permeability risk and avoids the negative association to fracking and does not involve ultra deep drilling into plutonic rocks.  

Closed loop systems extract heat through the process of conduction which has challenges such as limited conductive heat transfer through rock and high drilling costs of multilateral wells. Eavor Loop is a novel closed loop system addressing these issues through the drilling of long, closed loop multilateral wells in sedimentary basins.  This system can produce heat and power at temperatures between 100 and 180 degrees Celsius. 

This talk will demonstrate: 
       - Standard geological and geophysical work flows for oil and gas prospecting can be applied in closed loop geothermal settings for the determination of geothermal gradient, permeability and rock type
       - The potential for scalability in sedimentary basins across the globe
       - Overview of the Eavor Lite Pilot near Sylvan Lake, Alberta

Novel/Additive Information
       - Implications for reduction in exploration costs and the overall bankability of early stage geothermal projects

BIOGRAPHY
Jeanine Vany is an APEGA registered professional geologist with a career spanning over 15 years in the oil and gas industry. Her experience ranges from reservoir characterization, drilling and operations to full field delineation strategies, asset management, and acquisition. Ms. Vany has spent her career at foremost E&P companies such as EnCana, Devon and Total. She joined GLJ Petroleum Consultants in 2012, where she led the geoscience aspects of in-situ reserves and resource evaluations in addition to working deep basin unconventional plays. With a passion for people, projects and technology development, Ms. Vany led GLJ’s first oil sands technology panel, created and taught GLJ’s In-Situ Resource and Reserves course for industry professionals and spearheaded new business initiatives for the firm in unconventional resource plays.  
Jeanine holds an Honours B.Sc degree in Geology and Environmental Studies from Saint Mary’s University and a Business Essentials Certificate from the Haskayne School of Business, University of Calgary.

Division Profile
Vision: to educate CSPG Members about the Global Geothermal Industry through knowledge sharing from integrated geoscientific disciplines with the goal of highlighting the highly relevant skills of hydrogeologists, petroleum geologists, mining geologists, geophysicists and geomechanics specialists.  Special focus will be given to emerging Canadian Projects.

The Division will hold a series of brown bag lunches annually.

Lunch talks will start with a “snapshot of a producing geothermal project” alternating between igneous and sedimentary plays. 
Preliminary ideas for talks in 2019-2020:
      1) Geothermal 101 – focus on play types (including igneous), the global production of geothermal energy and the uses of geothermal energy.  
      2) An overview of the nascent Canadian Geothermal Industry – focus on research and development and emerging plays 
      3) Characterization of geothermal resources – focus on key parameters for defining resources/reserves and how to determine them.  
      4) Mapping hydrothermal reservoirs or hot sedimentary aquifers – a workflow for getting started.  Highlighting the relevant skill sets of hydrogeologists and petroleum geologists (Part 1).  
      5) Spotlight on new technologies – drilling, surface facilities or subsurface and the implications for development.
      6) Geo-Modelling of geothermal reservoirs
      7) Case Studies of existing geothermal plays 

Division success is dependent on Member interest and enthusiastic volunteers with a passion for knowledge sharing.  If you have an idea for a talk please contact Jeanine Vany at jeanine.vany@eavor.com.
