Enablement of High-Temperature Well Drilling for Multilateral Closed-Loop Geothermal Systems
Constructing a multilateral closed-loop geothermal system (MCLGS) requires directional tools and magnetic ranging tools in the bottom-hole assembly (BHA) to drill and intersect the wellbores and create the closed loop. The levelized cost of energy (LCOE) of such an MCLGS is largely driven by rock temperature – the hotter the rock, the more energy that is produced from a given well configuration, and the lower the levelized cost. However, these tools have a maximum temperature limit above which they are no longer functional. To enable drilling of high-temperature rock formations and thereby decrease the LCOE, methods for estimating the temperature of the BHA critical components are required. To simulate drilling, two models of increasing complexity were developed. The first model is a one-dimensional pseudo steady state wellbore + thermal resistance model capable of estimating the temperature and pressure profile of the drilling mud throughout the drill pipe and annulus. This model allows for the understanding of key performance drivers and technology requirements to achieve high-temperature drilling.

Yukon government proposes geothermal development legislation for late 2023
New green energy development legislation is being considered in the Yukon in order to harness the region’s subterranean renewable potential and decrease reliance on fossil fuels by switching to next-generation geothermal energy. CBC Yukon journalist Julien Gignac reported these regulations for geothermal exploration and extraction could be in place as soon as the fall of 2023. The article follows closely on the heels of an October report detailing the predicted impacts of climate change on the Territory’s unique landscape and way of life.
Federal government introduces geothermal education initiative in Nova Scotia
First Nations and rural communities in Nova Scotia are getting ready to turn up the heat on geothermal energy. A new federal program dubbed Community Geothermal Resource Capacity Assessment and Training, or GeoCAT for short, was announced in early November. CBC’s Erin Pottie’s article covering the announcement of the program describes how the $1.3 million budget will be spent to educate stakeholders and community members about the Maritime province’s next-generation geothermal energy potential, and accessible technologies that can be used to access it.
Eavor-Loop™ Dispatchability Case Study for PPA with Utility
Eavor-Loop™, a multilateral closed loop geothermal system, is a clean firm power generation technology that can be scaled to phase out fossil fuel baseload and peaker plant generation. Eavor has partnered with a major US utility for the large-scale development of Eavor-Loops to supply clean firm power to the grid. The favorable geothermal gradients in the region, coupled with the scalability of the Eavor-Loop™ solution, indicate that there is >1.2GW of potential Eavor-Loop™ generation on the selected project licence area located in southwestern USA.
