In $218 million DOE-funded research project, University of Utah scientists aim to make enhanced geothermal a key part of world's energy portfolio.

A major University of Utah-led geothermal research project, funded by the U.S. Department of Energy (DOE), achieved a critical breakthrough in April after hydraulically stimulating and circulating water through heated rock formations a mile and a half beneath its drill site in the Utah desert and bringing hot water to the surface. The test results are seen as an important step forward in the search for new ways to use Earth’s subsurface heat to produce hot water for generating emissions-free electricity. The successful well stimulations and a nine-hour circulation test were the fruits of years of planning and data analysis at the Utah FORGE facility near Milford, 175 miles southwest of Salt Lake City.

More than two-thirds of the water that was injected underground and pushed through the fractured formation—acquiring heat on the way—was extracted from a second well, offering proof that enhanced geothermal systems (EGS) technology could be viable, according to John McLennan, a co-principal investigator on the project formally known as the Utah Frontier Observatory for Research in Geothermal Energy, or Utah FORGE.

“Nine hours is enough to prove that you have a connection and that you’re producing heat,” said McLennan, a U professor of chemical engineering. “It really is a Eureka moment. It’s been 60 years coming, and so this actually is significant.”

Utah FORGE is a $218 million research project, involving numerous institutions and industry partners, funded by a DOE grant to the U’s Energy & Geoscience Institute. The project aims to develop and de-risk new geothermal technologies that could potentially be deployed all over the world, not just where conventional geothermal plants are sited.

For this recent test, FORGE personnel and industry specialists directionally drilled two boreholes—one for injecting water underground and the other for extracting it. The injection well is 10,897 feet long and drops to a depth of 8,559 feet below the surface. “We speculate, and we’ll see this in the 30-day test, that as we fill the fracture system back up, this number is going to get to where I’m suspecting it’s 85 to 90% efficiency,” McLennan said.

Equally promising was the absence of any noticeable ground shaking associated with the stimulations and circulation test. U seismologists led by geology professor Kris Pankow, associate director of the U of U Seismograph Stations, are overseeing an extensive network of seismometers to document ground movement associated with the project.

Wolves and Humans in Rural Turkey

Utah biologists track gray wolves with GPS collars and camera traps as their numbers rebound into populated parts of northeast Turkey.

After 14 years of gathering and analyzing field data, an international research team led by University of Utah biologist Çağan Şekercioğlu has released the first and only study of gray wolf movements and ecology in Turkey. Using GPS collars and camera traps, researchers tracked seasonal variations of wolves’ range sizes in the highlands of Turkey’s rural northeastern corner, where people are widely present during the summer but mostly absent in the winter when the area is completely snowbound. The team was surprised to discover human presence had no effect on wolf movements.

“Even though human activity changes drastically, wolves are not taking advantage of that by increasing their home range size or changing their home range size between the seasons when humans are there and when they’re not there,” said J. David Blount, lead author of the study published this month in the journal Wildlife Biology. “Theoretically they have a lot of different needs during these times that should be fluctuating, especially with the dispersing wolves.”

“Wolves are very adjustable, which leads to many exciting behavioral adaptations,” said Blount, a graduate student in Şekercioğlu’s lab. “However, studies are pretty context-dependent.”

Since the mid-1990s, wolves have been making a comeback following re-introductions in the Yellowstone region, Arizona and, most recently, western Colorado. The wolf situation in eastern Turkey is completely different, according to Şekercioğlu, a professor of biology. While wolves have been a problem for livestock operations, shepherds and ranchers have learned to live with the apex predator with the help of Anatolian sheepdogs, which protect cattle and sheep without harming the wolves.

The study area covered 550 square kilometers surrounding Sarıkamış, a town of 15,500.  Over 14 research seasons, running from mid-May to mid-August, the research team captured 46 wolves and fitted them with GPS collars, which recorded a location every five hours and are designed to fall off after two years. The cameras yielded 26,000 photos of wildlife and countless others that recorded animals other than wildlife.

According to the study, as wolves resettle areas near towns, understanding how wolves adjust their temporal and spatial patterns in human-dominated landscapes can contribute to their conservation. An ornithologist who studies tropical songbirds, Şekercioğlu began eying wolves when he moved from Stanford University in 2010 and used startup funds provided by the University of Utah to initiate the project, also supported by grants from Fondation Segré, the Sigrid Rausing Trust and the Whitley Fund.
