Analysis of the Borehole Effect in Borehole Radar Detection [PDF]
The directional borehole radar can accurately locate and image the geological target around the borehole, which overcomes the shortcomings that the conventional borehole radar can only detect the depth of the target and the distance from the borehole ...

The 2020 earthquake sequence and seismic hazard scenario of Mizoram state in northeast India
The Mizoram state of India lies in close proximity to the active Indo-Burma subduction zone and had experienced several moderate to large earthquakes, including the M7 event in 1938. Since 2015, only two events with 5<M<6 have occurred in the area,

Numerical modelling of deep coaxial borehole heat exchangers in the Cheshire Basin, UK
Few deep geothermal wells have been drilled in the Cheshire Basin resulting in high geological and financial risks of such developments. In recent years the focus of exploiting deep geothermal resources in the UK has moved towards lower risk strategies ...
