RELATIONSHIPS BETWEEN SHALE CONTENT AND GRAIN-SIZE PARAMETERS IN THE SAFANIYA SANDSTONE RESERVOIR, NE SAUDI ARABIA

The grain-size distribution of a sediment is controlled by the hydrodynamics of the depositional environment. There is a relationship between the petrophysical properties of a reservoir rock, such as porosity and permeability, and the grain-sie distribution. Therefore, the grain-size distribution is important in interpreting both the depositional environment and the petrophysical properties of a sedimentary rock. Determination of the grain-size parameters from gamma-ray and/or other shale-indicator well logs may be possible if the necessary correlations are established

Imaging of degeneration, inflammation, infection, ossification, and calcification of the intervertebral disk

Diseases of the intervertebral disk may result from several multifactorial pathophysiologic processes. In this chapter, we discuss the normal anatomy of the intervertebral disk along with their anatomic variants and pathologic processes responsible for disk disease and their imaging correlates on conventional radiography, computed tomography, and magnetic resonance imaging
