... of relatively high-porosity (20-45%) chalks, marls, and oil shales with kerogen. This paper describes preliminary measurements, analyses of thermal hydrological mechanical (THM) properties and expected borehole stability for a potential high level nuclear waste borehole repository in Israel. This effort is part...

... Abstract: We investigated the rock physics of immature organic-rich chalk from the Late Cretaceous Ghareb and Mishash formations in the Shefela basin, central Israel, and its variation upon pyrolysis-induced maturation. The study was carried out on core samples from a ~280 meters sequence...

... Abstract: Based on the assumption of Vertical Transverse Isotropy (VTI), we investigated the ultrasonic velocity and anisotropy of organic-rich chalks (ORC). These chalks, from the late Cretaceous Ghareb and Mishash formations in Israel, have a wide range of porosity (0 – 45 PU), high...

.... INTRODUCTION Masada is the most important national monument in the state of Israel, as it draws over 800,000 domestic and international visitors a year. Mount Masada is situated in the Judean Desert on the western margins of the seismically active Dead Sea rift valley (Figure 1). The Roman King Herod...

... ABSTRACT: The results of geotechnical feasibility investigations all over Israel, indicate that Eocene formations (chalk and silicified chalk) offer the most suitable properties, as being the potential rock for underground storage for distillates. Explorations included preliminary geological...
