Skoltech researchers and their industry colleagues have created a data-driven model that can forecast the production from an oil well stimulated by multistage fracturing technology. This model has high commercialization potential, and its use can boost oil production via optimized fracturing design.
New research has revealed when it comes to flying the largest of birds don't rely on flapping to move around. Instead they make use of air currents to keep them airborne for hours at a time. A study has revealed the Andean condor - the world's heaviest soaring bird - actually flaps its wings for one per cent of its flight time.
Measurements by the GRACE-FO satellite mission show a decline in water storage in Central Europe by up to 94 percent compared with seasonal fluctuations. The changes are so serious that a recovery within one year is not to be expected. The water shortage in the years 2018 and 2019 is thus the largest in the entire GRACE and GRACE-FO measurement campaign of almost 20 years. The results were published in the journal Geophysical Research Letters.
Archaeological glass contains information about the movement of goods and ancient economies, yet the understanding of critical aspects of the ancient glass industry is fragmentary. Until now, it has been challenging to scientifically determine the origin of the colourless and clear glass, which was particularly favoured by the Romans. The Romans distinguished between two types of clear glass: Alexandrian and Levantine. Now researchers have found a way to localize the furnaces of the two types.
Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles. It is continuously generated by the motion of liquid iron in Earth's outer core, a phenomenon called the geodynamo. Despite its fundamental importance, many questions remain unanswered about the geodynamo's origin. New work examines how the presence of lighter elements in the predominately iron core could affect the geodynamo's genesis and sustainability.
What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of this "dead water" being understood. A French team has explained this phenomenon for the first time.
A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth's magnetic field may take place 10 times faster than previously thought.
The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018.
Intensive erosion can temporarily change the earthquake activity (seismicity) of a region significantly. This has now been shown for Taiwan by researchers from the GFZ German Research Centre for Geosciences in cooperation with international colleagues. They report on this in the journal "Scientific Reports".
Analysis of seismometer data from the InSight Martian lander revealed that different types and frequencies of ambient low-magnitude "microtremors" on Mars were associated with different sources, and some reflected daily variations in wind and solar irradiance, either in distant locations or near the lander. These findings will contribute to future projects seeking to model and monitor the Martian subsurface.
