Project Development Strategy and Economic and Investment Evaluations

Friday & Saturday, October 12 & 13

Room: Naples 7                8am - 5pm
Cost: $550 (Member), $600 (Non-Member), $175 (Student)

Led by: Manon Stöver, Mehul Patel and Steve Burden of Veizades & Associates, Inc

Join us for a 2-day workshop focusing on commercial development strategies for well field, resource production facilities, power production facilities, and infrastructure. Participants will develop economic and investment decision processes and a computer model using capital cost estimates, operating and maintenance costs, and revenue from power sales to drive the calculations of internal rate of return, net present value, and payback period. A case study for a successful project will be presented using a USTDA-funded feasibility study along with other real-world experiences shared by participants and instructors.

Who Should Attend?

The workshop is designed for students, engineers, geoscientists, drillers and project managers tasked with advancing geothermal projects from the exploration stage to commercial power generation.

Day 1 - Geothermal Project Development Strategies:

Maximizing the success of Geothermal Projects requires a methodical, science lead, and engineering supported planning that will drive the economic model. The challenges in developing geothermal projects in the USA and foreign countries will be highlighted with a step by step approach to minimize risk, shorten project schedules, and maximize success. The presentation will be broken into five 1-hour blocks with questions and answer periods after each block.

  1. Identification of Geothermal Area, Exploration Planning, Early Financing Evaluation, and Permitting Owner Staffing Requirements
  2. Site investigations, Civil Engineering Requirements, Procurement Schedule, Staffing and Management Requirements
  3. Exploration Drilling, Flow Testing, Data Interpretation, Power Cycle Selection, and Project Feasibility Report
  4. Exploitation Drilling, Construction Planning, Contracting Plan, Procurement and Logistics, and Construction Financing
  5. Construction, Quality Control, Inspection Staff, Owner Construction Staff, Start-up and Commissioning.

Day 2- Economic and Investment Evaluation:

Preparing the economic and investment evaluation is critical to obtaining management approval, construction financing, and long-term equity investments. This session will focus on the development and use of commonly used metrics of cash flow to determine the value of the investment and the sensitivities of the primary investment drivers. The presentation will be broken into blocks with questions and answer periods after each block. Bring your computer as the workshop participants will develop and present computer models.

  1. Definition and development of Net Present Value, Internal Rate of Return, and Payback
  2. Capital investment cash flow
    •  Optimization of well size and number
    •  Capital investment comparison due to power cycle selection
    •  Satellite separation vs one separation station
  3. Operation and maintenance (O&M) expense and electric power sales revenue
  4.  Sensitivity due to:
    • Schedule
    • Cost of money
    • Success of development drilling
    • Capacity factor and changes in electric sale price
    • O&M expense
  5. Case study summary

Evolution of Geothermal Resource Models: From Surface Exploration to Field Development and Reservoir Management 

Friday & Saturday, October 12 & 13

Room: Naples 6             8am - 5pm
Cost: $550 (Member), $600 (Non-Member), $175 (Student)

Led by: Bastien Poux, Gene Suemnicht and Jeff Witter
Assisted by: Marino Baroek, Jim Faulds and Holly McLachlan

With a focus on the graphical aspects, this workshop will present the methodologies employed in the industry to accurately build resource models at the different stages of the exploration and development of a geothermal field. This workshop will follow the typical development order of any geothermal project; starting from the initial conceptual models resulting from the surface exploration phase, to the integration of sub-surface data in three-dimensional models during the development phase and the use of advanced numerical models to manage the reservoir during the production phase. During this workshop, numerous case studies from around the world will be studied in detail with the participants, including some of the world’s largest geothermal fields located in the United States, Indonesia and Iceland. Bring your computer as participants will have a hands-on experience!
