PETROPHYSICAL EVALUATION OF WELL LOG DATA TO ANALYSE RESERVOIR PROPERTIES IN OGBA FIELD, NIGER DELTA, NIGERIA [PDF]
This study evaluates the petrophysical characteristics of Ogba Field in the Niger Delta Basin, Nigeria, using well log data (gamma ray, resistivity, neutron, and density logs) from two wells (Ogba-1 and Ogba-2) and core data from Ogba-4ST.

Investigations of the pi N total cross sections at high energies using new FESR: log nu or (log nu)^2 [PDF]
We propose to use rich informations on pi p total cross sections below N= 10 GeV in addition to high-energy data in order to discriminate whether these cross sections increase like log nu or (log nu)^2 at high energies, since it is difficult to ...

Orthogonal Matching Pursuit: A Brownian Motion Analysis [PDF]
A well-known analysis of Tropp and Gilbert shows that orthogonal matching pursuit (OMP) can recover a k-sparse n-dimensional real vector from 4 k log(n) noise-free linear measurements obtained through a random Gaussian measurement matrix with a ...

Asteroseismic surface gravity for evolved stars [PDF]
Context: Asteroseismic surface gravity values can be of importance in determining spectroscopic stellar parameters. The independent log(g) value from asteroseismology can be used as a fixed value in the spectroscopic analysis to reduce uncertainties due ...

Petrophysical Well Log Analysis through Intelligent Methods [PDF]
Abstract This work is focused on exploring the applicability of intelligent methods in assessing porosity and permeability in the context of reservoir characterization. The main motivation underlying our study is that appropriate estimation of reservoir petrophysical parameters such as porosity and/or permeability is a key step for in ...
