This early journaling system has evolved to encompass lowering logging tools into the wellbore via wireline in order to measure porosity, resistivity, permeability, temperature, water saturation ...

Collisions between neutron stars, which are governed by the laws of Einstein’s Theory of Relativity, lead to strong bursts of gravitational wave emission. In 2017, scientists directly measured ...

Radioactive sealed sources or neutron generators, known as logging tools, are an integral part of the equipment used in well logging. Logging tools are lowered into a borehole, drilled into the ground ...

Description Borehole logging is a basic tool in the exploration for and delineation of uranium deposits. The radioactivity associated with the uranium can be used for the quantitative evaluation of ...

As a proof of concept the team have shown how the combination of heat and low intensity visible and UV light could in future be used as a precise, low-cost tool for 3D printing of self-assembling ...
