Earthquakes that last minutes rather than seconds are a relatively recent discovery, according to an international team of seismologists. Researchers have been aware of these slow earthquakes, only for the past five to 10 years because of new tools and new observations, but these tools may explain the triggering of some normal earthquakes and could help in earthquake prediction.
Human-made earthquake risk reduced if fracking is 895m from faults
The risk of human-made earthquakes due to fracking is greatly reduced if high-pressure fluid injection used to crack underground rocks is 895m away from faults in the Earth's crust, according to new research.
Lessons from Pohang: Solving geothermal energy's earthquake problem
A geothermal energy project triggered a damaging earthquake in 2017 in South Korea. A new analysis suggests flaws in some of the most common ways of trying to minimize the risk of such quakes when harnessing Earth's heat for energy.
The deployment of geothermal systems is being hindered by insufficient permeability of the reservoir rock, excessive induced seismicity during reservoir stimulation, and geochemical reactions accelerated by high temperature that lead to corrosion and scaling. To overcome these challenges, interdisciplinary approaches that investigate relevant processes occurring during geothermal energy exploitation are necessary
Micro-Slimtube Shrinks EOR Screening From Months to a Week
Interface Fluidics carved out a niche for itself in the oilfield testing sector a few years ago with a new alternative to coreflooding. Now, along with Equinor, the Calgary-based company is taking on another industry laboratory stalwart: the slimtube test.
