Stanford Geothermal Workshop

STANFORD GEOTHERMAL WORKSHOP 43rd ANNUAL

Dates: February 12-14, 2018
Location: Frances C. Arrillaga Alumni Center
326 Galvez St., Stanford, CA 94305-6105

Program:
Come join the 43rd anniversary of the Stanford Geothermal Workshop -- one of the world's longest running technical meetings on the topic of geothermal energy! For this year's preliminary schedule, see here (2018)

Goals:
The goals of the conference are to bring together engineers, scientists and managers involved in geothermal reservoir studies and developments; provide a forum for the exchange of ideas on the exploration, development and use of geothermal resources; and to enable prompt and open reporting of progress. We strongly encourage all scientists and engineers involved in geothermal reservoir technology to attend the workshop.

Topics:
Papers will be presented on recent research relating to geothermal reservoirs including:

  • Case Studies: reservoir response to production, effects of injection, scaling characteristics
  • Enhanced Geothermal Systems (EGS): current and future activities
  • Engineering Techniques: reservoir simulation, empirical methods, well tests, tracers
  • Field Management: strategies for exploitation, injection, scale inhibition
  • Exploration: geophysics, geochemistry, geology, heat flow studies, outflows
  • Drilling and Well Bore Flows: well stimulation, bore flow modeling, hydro-fracturing, scaling
  • Low Enthalpy Systems: applications of heat pumps, hot dry rock technology
  • Geosciences: application of geophysics, geochemistry, thermodynamics and fluid mechanics.

UTAH FORGE 2: 58-32 Recap

by Ozgur Balamir

Ozgur Balamir presented 58-32 Recap February 12, 2018. This presentation detailed 58-32 well objectives and the impressive results. A scientific test well (MU-ESW-1) was drilled to a depth of 2,296 m (7,536 ft) to obtain direct measurements of rock type, temperature, permeability and stress within the Utah FORGE reservoir.

Objectives Meet:

  • Temperature, permeability, stress measurements, and rock type satisfy DOE criteria
  • Collected core and cuttings, ran geophysical logs and pressure-temperature surveys
  • Injection test conducted; these results are under evaluation
  • Well was completed significantly deeper, (7%), faster (23%), and under budget (10%)
  • Logged a relative MSE (this will be presented in paper at 2018 Geothermal Resource Council Annual Meeting and Expo) and tried out several different types of hard formation bits with a mud motor
  • Adapted quick-lock wellhead, foam cementing and ACP technologies
  • The Lesson Learned report was delivered on time

The complete paper is available for download on our publications page.

Experience and Leadership

Our company has provided consulting engineering and on-site management services in over 16 countries and at over 95 geothermal development projects worldwide. GRG is well suited for international services and we have the logistical capabilities to form partnerships for in-country business operations. In addition, as leaders in the geothermal industry, our engineering and geoscience staff regularly author peer-reviewed publications, and present case histories and research findings as speakers at geothermal industry conferences. GRG can provide drilling engineering and management services through on-site drilling experts and off-site engineering and geoscience specialists, with proven success internationally and locally.

Our industry leading network of drilling, geoscience, and reservoir engineering experts are widely recognized throughout the worldwide geothermal industry for providing consistent geothermal development expertise. GRG’s drilling supervision team is recognized as experienced, dedicated, and responsive to customer needs. We pride ourselves in the completion of production and injection wells that remain mechanically sound for the planned life of a geothermal power facility. Our domestic and international customers have realized substantial savings in well completion cost and quality by incorporating our world-class drilling engineering skills in their project development team.

Our Company Site Representatives generally have 15-20 years of direct field experience in geothermal drilling and site management. We have a large selection of personnel available for any geothermal project. GRG drilling supervisors are among the most experienced in the world. GRG supervisors have been trained to deal with the problems common to geothermal drilling, including loss of circulation, special cementing techniques, and geothermal well control. GRG select its supervisors with a keen sense of the need for the breadth of skills required to successfully drill all types of geothermal wells.
