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.
