THE ROLE OF FLOW RATE AND FLUID ALKALANITY ON FINE PARTICLES MOVEMENT AND INFLUENCING THE PETROPHYSICAL PROPERTIES OF RESERVOIR SANDSTONE

The Role of Flow Rate and Fluid Alkalanity on Fine Particles Movement and Influencing the Petrophysical Properties of Reservoir Sandstone

Permeability decline related with fine migration is one of the most widespread phenomenon that occurs in most oil reservoirs.Fine migration is intensive in sandstone reservoir, but frequently misinterpreted.Movement of fine particles might be problamatic to identify and even not easy to predict and interpret.The main goal of this study is to invest

Sub-nanometer depth resolution and single dopant visualization achieved by tilt-coupled multislice electron ptychography

Abstract Real-space, three-dimensional imaging of atomic structures in materials science is a critical yet challenging task.Although scanning transmission electron microscopy has achieved sub-angstrom lateral resolution through techniques like electron ptychography, depth resolution remains limited to only 2 to 3 nanometers using single-projection
