Over the last decades, biodiesel-based drilling fluids have drawn attention of researchers due to their biodegradability, low cost, high flash point compared other synthetic-based fluids. This review study discusses development and analyzes characteristics biodiesels (based on required range values for properties) that lead better understanding in choosing proper biodiesel Although, using as ba...

Deep (>300 m) subsurface hydrochemical data are important components of geological investigations of potential radioactive waste disposal sites. These data can be interpreted to yield information that supports conceptual hydrogeological models, constrains palaeohydrogeological evolution and characterises subsurface hydrochemical conditions of a site. The most important sources of these data are...
