Estimating arsenic concentrations in Bihar (India), a geostatistical approach using DEM data

Bihar is a densely populated area located in the Middle Ganga Plain (MGP) in India. The Ganges' sinuous nature in the MGP created a vast amount of point bar structures within the floodplain. In 2003 it was discovered that high arsenic concentrations are present in the shallow groundwater aquifers, especially in the elevated point bars. According...

Modelling the spectral gamma-ray log: The influence of provenance and selective transport

In clastic rock, the interpretation of facies from the spectral gamma-ray log should be applied with caution because a consistent relationship with gamma-ray is lacking due to variations in provenance and/or diagenesis. In this thesis the use of the gamma-ray log for the derivation of source rock characteristics and/or diagenesis is examined....

Facies and permeability prediction based on analysis of core images

The present standards for core interpretation do not contain the acquisition of high resolution images from core slabs; images are taken on a very low resolution under a poor light source for administrative purposes only. The advantages of taking high resolution images and subsequent analysis of these images could be substantial and are...

The relation between particle settling velocity and shape: A critical review

This research has tried to find a relation between particle settling velocity and shape. This was done by taking the settling velocity log-contrast of a non-spherical particle and an equivalent spherical particle. This log-contrast should be the logarithmic function of a certain shape factor. Settling data of several shapes were taken from...
