Word of the Week – Granite


Light colored, coarse grained, intrusive rock with a felsic (silica-rich) composition that is mostly made of quartz, sodium and potassium-bearing feldspar, and plagioclase. Minor amounts of other minerals can include mica (muscovite, biotite), hornblende, magnetite (iron oxide), and ilmenite (titanium-iron oxide).

Did You Know that China is home to one of the oldest known geothermal pools in the world?


Did you know… that China is home to one of the oldest known geothermal pools in the world?

Huaqing Pool, located near Mount Li in the province of Shaanxi, China, has a long and storied history. The complex of hot springs has been in use for close to three millennia and was a famous getaway spot for multiple Chinese emperors. The ancient Chinese utilized the natural geothermal activity in the area for cleaning and bathing. Today geothermal energy is widely developed in China primarily for direct use and district heating. Moreover, the source of this heat relates to a dynamic geological history that includes the collision of continental plates which produced the Himalayas and the Tibetan plateau.

The pools at Huaqing make up a large hot spring complex. The first stone pool was built during the Qin Dynasty from 206 BC to 220 AD, but the history of the site dates back even further, to the Western Zhou Dynasty, from 1046 to 771 BC. King You built the Li Palace in that era to enjoy the natural beauty, starting a long history of many emperors coming to visit. The area has been expanded since the original little stone pool was first constructed back in the Qin Dynasty. Today the site comprises many pools, historical sites, and even a daily performance! It’s a full-fledged tourist destination.

The Song of Everlasting Sorrow is a show performed daily during the warm months, between April and October. It tells the love story of Emperor Xuanzong and Yang Guifei, with over 300 actors in extravagant costumes. It is also home to the beautiful Nine Dragon Lake. The glassy water surrounds nine stone dragon carvings and is home to Koi fish.

The five historical hot springs on the main site are not available for public use, but there are plenty of hotels and resorts in the surrounding area that are open to everyone. It’s easy to enjoy a day at the Huaqing Pools, learning about the long history of the area, before heading back to your resort to experience the same waters that the ancient Chinese emperors did thousands of years ago.















Word of the Week – Flowback


Return flow of slickwater that was injected during a stimulation. This is a highly controlled process in which well head pressure is reduced to allow managed fluid recovery. Fluids are commonly sampled and chemically analyzed to determine the effects of injection and stimulation in the reservoir.

            • Concept Papers are due October 10, 2022, at 2:00 PM MDT

SALT LAKE CITY, UT., Aug.15, 2022 - The University of Utah and Utah Frontier Observatory for Research in Geothermal Energy (FORGE) are pleased to announce Utah FORGE Solicitation 2022-2. This is the second formal call for research proposals on enhanced geothermal systems technologies from the Utah FORGE Program. Up to 17 awards are anticipated for up to a total of $44,000,000.

A pre-recorded informational webinar will be available on August 23, 2022.

The submission deadline for the two-page Concept Papers has been set for October 10, 2022, at 2:00 PM MDT.

The topic areas for technology testing and evaluations, their maximum potential funding level and the potential number of awards include:

Topic Title Potential Funding Potential Number of Awards
6 Adaptive Induced Seismicity Monitoring Protocols $2,000,000 2 to 3
7 Alternative Stimulation Schemes $8,000,000 2 to 3
8 Field Scale Experiments to Measure Heat-Sweep Efficiency $8,000,000 2 to 4
9 High Temperature Proppants $6,000,000 2 to 4
10 Multiset Straddle Packers for Open Hole Operations $20,000,000 2 to 3

Each award has a maximum period of performance of three years.

“We are pleased to offer this second funding opportunity. It allows us to engage a wide range of researchers in helping to build on the many successes already realized at Utah FORGE,” said Joseph Moore, Ph.D. and Principal Investigator of the project.

Utah FORGE is a dedicated underground field laboratory sponsored by the U. S. Department of Energy’s Geothermal Technologies Office. Its goal is to develop, test, and accelerate breakthroughs in Enhanced Geothermal System, or EGS, to untap the vast potential of geothermal energy and advance its development across the US and around the world.

About Utah FORGE: The Utah FORGE site is located near the town of Milford in Beaver County, Utah, on the western flank of the Mineral Mountains. Near term goals are aimed at perfecting drilling, stimulation, injection-production, and subsurface imaging technologies required to establish and sustain continuous fluid flow and energy transfer from an EGS reservoir. It is funded by the U.S. Department of Energy and managed by the University of Utah’s Energy & Geoscience Institute. For more information, please visit our website at https://utahforge.com.

Word of the Week – Slickwater


Water that is injected during reservoir stimulation. It is modified with low concentrations of chemical additives, including polyacrylamide, that reduce friction and enhance fluid flow. Proppant (e.g., sand) is often added to help keep stimulated fractures open.
