Reverse Time Migration with Modified Nearly Analytical Discretization: Efficient Large-Scale High-Resolution Imaging and Aliasing Suppression

Abstract Reverse time migration (RTM) requires numerically solving the partial differential wave equation because analytical solutions are infeasible. A significant challenge in numerical methods arises from inaccuracies in derivatives approximation, making the numerical wave vel...

Field demonstration and integrated productivity-economics assessment of multi-lateral geothermal wells enabled by directional steel shot drilling

This study explores the potential of multi-lateral slim-hole drilling to enhance reservoir access and connectivity in fractured geothermal reservoirs. At the core of this work is Directional Steel Shot Drilling (DSSD), a technology that combines conventional mechanical drilling w...

Quantitative Assessment of Se(p,xn) Routes to Medical Bromine Radioisotopes

Abstract This study investigates proton-induced reactions on enriched selenium targets, focusing on the production of bromine radioisotopes, which are of significant medical relevance for both diagnostic imaging and therapeutic applications. The study employs Monte Carlo samples...
