In our last SEP report, we introduced an AVO dataset consisting of seismic, petrophysical and well-log information which was provided by Mobil as part of an AVO workshop (?). The prestack seismic data are heavily contaminated by free-surface and water-bottom multiple reflections, and thus represent a challenge for true-amplitude processing. We described our preliminary preprocessing work and di...

Nuclear magnetic resonance (MR) (NMR) is commonly used for the determination of rock porosity, as well pore size distribution (PSD) and tortuosity, required to handle hydrocarbon exploitation. Emerging technologies NMR equipment now enable visualization porosity using imaging (MRI). Currently, single-point most common MRI technique employed, but diffusion-weighted has been attracting attention ...

The main purpose of this study is to estimate hydrocarbon potentialities Yamama Formation (Valanginian–Early Hauterivian) by using assessment technique links up between gamma ray spectrometry logs and other conventional open hole for determining the petrophysical properties units in Subba oil-field oil water contact as well. Lower (YB); considered reservoir unit, aptly composed shallow high dep...

We combine a new pore-scale model with a reservoir simulation algorithm to predict gas production in gas-bearing shales. It includes an iterative verification method of surface mass balance to ensure real-time desorption-adsorption equilibrium with gas production. The pore-scale model quantifies macroscopic petrophysical properties of formations using an algorithm of gas transport in porous med...
