Geothermal Drilling

Drilling and Completions


This course provides an overview of geothermal energy, focusing on the concepts, equipment, materials, technologies, techniques and practices involved in drilling geothermal wells and how these differ from those used for drilling oil and gas wells. It is meant to provide insights into factors to consider in designing and engineering a geothermal well in relation to the type of geothermal system being developed. Geothermal well planning, with focus on rig selection, consumable materials and the tools/equipment that will be involved in the geothermal well construction process will also be discussed.

Course Objective:

  • Get an overview of geothermal drilling and what makes it different from drilling operations for oil and gas wells.
  • Acquire insights on factors to consider in planning, engineering and designing a geothermal well.
  • Know the materials, equipment, technologies and methodologies required to be able to drill and construct geothermal wells.
  • Gain familiarity with geothermal drilling practices as it pertains to the different phases of the drilling operation.
  • Identify potential problems that can be encountered in geothermal drilling and how they are typically addressed.
  • Learn about advanced and emerging technologies that are in the process of being deployed in drilling geothermal wells.
  • Visit a geothermal field under development and observe the output of the drilling process.

Engineers are responsible for enhancing their professional competence throughout their careers. Licensed, chartered, and/or certified engineers are sometimes required by government entities to provide proof of continued professional development and training. Training credits are defined as Continuing Education Units (CEUs) or Professional Development Hours (PDHs).

Attendees of SPE training courses earn 0.8 CEUs for each day of training. We provide each attendee a certificate upon completion of the training course.


Steve Nas

Steve Nas holds an MSc in Drilling Engineering from The Robert Gordon University in Aberdeen and over 35 years of oilfield experience of which 32 years as a drilling engineer including 15 years as a wellsite. Steve started his career in 1977 as a Mud logger. After which he had worked with Shell and then Smedvig and became involved in underbalanced drilling operations drilling numerous UBD wells in the North Sea, Indonesia, Thailand, and Colombia as well as in other parts of the world. In 2004 he joined Weatherford in Asia Pacific followed by the SPT group in 2011 where he headed their well engineering group further specializing in well control and hydraulic flow modeling technology. In 2012 SPT was acquired by Schlumberger and he is now Adviser for Drilling Software in Schlumberger.

Julmar Shaun S Toralde

Julmar Shaun S. Toralde spent six years with Negros Oriental State University (NORSU), Philippines as Instructor and Department Chairperson of the Geothermal Engineering Program, also serving as a Research Coordinator of the College of Engineering and Architecture, and Research Journal Editor of the university, from 1999 to 2005. Shaun has served Weatherford previously as Controlled Pressure Drilling (CPD) Engineer and as CPD&T Engineering Coordinator and has been personally involved in geothermal aerated drilling projects in the Asia Pacific region. He also spearheaded the successful delivery of the globally pioneering deepwater managed pressure drilling (MPD) projects. He was also Engineering Manager - Asia Pacific, Well Construction Services, and is currently Engineering / Sales Manager, Secure Drilling Services – Asia Pacific, as well as Engineering Lead, Well Engineering and Project Management - Asia Pacific, with Weatherford, where he is managing more than 50 engineers in developing novel solutions for critical environments using advanced well construction technologies.
