The implications of K-Ar glauconite dating of the Diest Formation on the paleogeography of the Upper Miocene in Belgium [PDF]
The glauconite-rich Diest Formation in central and north Belgium contains sands in the Campine subsurface and the hilly Hageland area that can be distinguished from each other.

This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

We analyzed the current stress state on the Nojima Fault, the source of the 1995 Mw 6.9 Kobe (Japan) earthquake, using breakouts in a borehole through the fault to a depth of ~1,000 m in 2017. The main fault was found at a depth of 529.3 m, with a damage

Study of the plasma flow interaction with the borehole surface in the process of its thermal reaming [PDF]
Purpose. Study of the plasma flow interaction with the borehole surface in the process of its thermal reaming for determination of transient temperature distribution along the borehole surface and the average coefficient of heat transfer from the plasma ...

Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an
