Drilling for Geothermal Resources: EGS
Recorded On: 04/14/2021
In the transition towards alternate energy sources, geothermal offers a green baseload source, tapping “The Sun Beneath Our Feet”. Yet investment in the development of Enhanced or Engineered Geothermal Systems (EGS) has been slow. There are several reasons for this: perception, technology readiness and investment. EGS has had some hiccups, and one of these is the level of seismicity associated with reservoir stimulation. A swarm of tremors up to magnitude 3.4 in the GeoPower Basel well (2007) was widely publicized and created a significant barrier to the development of EGS close to the urban centers. EGS and other geothermal wells are often drilled using old technology – hence costly drilling operations and a perception that drilling risk is high. Drilling can be more than 50% of the development ticket. This high cost and its associated risk often acts as a barrier to investment.
This webinar will review Enhanced or Engineered Geothermal Systems (EGS), and what is required to drill these systems at depth. It will highlight techniques that can be moved from oil & gas to geothermal (such as horizontal well drilling capability), and highlight areas in which R&D has occurred or is needed, particularly high temperature drill bits, fluids, drilling systems and MWD tools. With active investment in R&D for Enhanced Geothermal Systems, significant progress can be made in transferring oil and gas technology to an alternate energy source.

Chief Consulting Scientist, Baker Hughes
John Macpherson is a Chief Consulting Scientist for Baker Hughes. He holds a BSc (Hons) in Geology from the University of Glasgow. During his more than 40 years in the oil industry he has participated in exploratory drilling operations – primarily in remote areas of South Amercia – and in various positions in drilling technology R&D. These include drilling dynamics, drilling automation, and high temperature geothermal drilling systems. He has published about 50 papers, holds more than 30 granted patents, was the 2014 to 2016 Chairman of the SPE Drilling Systems Automation Technical Section, a past member of the JPT editorial committee, and a 2016 SPE Distinguished Lecturer.
