Quantum computer-assisted global optimization in geophysics illustrated with stack-power maximization for refraction residual statics estimation

Much of recent progress in geophysics can be attributed to the adaptation of heterogeneous high-performance computing architectures. It is projected that the next major leap in many areas of science, and hence hopefully in geophysics too, will be due to the emergence of quantum computers. Finding a right combination of hardware, algorithms, and...

Reversionary rotation of actuated particles for microfluidic near-surface mixing

The off-axis motion of particles actuated by axial magnetic or gravitational forces is studied in fluidic channels. Single actuated superparamagnetic micro-particles starting from channel walls travel towards the channel center and show unforeseen reversionary rotation phenomena. Different stages of co- and counter-rotation are observed in both...

Lithosphere tectonics and thermo-mechanical properties: An integrated modeling approach for enhanced geothermal systems exploration in Europe

For geothermal exploration and the development of enhanced geothermal systems (EGS) knowlegde of temperature at drillable depth is a prerequisite for site selection. Equally important is the thermo-mechanical signature of the lithosphere and crust which allow to obtain critical constraints for the crustal stress field and basement temperatures...

Full-waveform static corrections using blind channel identification

Near-surface wavefield perturbations can be very complex and completely mask the target reflections. Despite this complexity, conventional methods rely on parameterizations characterized by simple time and amplitude anomalies to compensate for these perturbations. Determining and compensating for time shifts is generally referred to as (residual...
