Carbonate rocks are in general complex and commonly contain compound pore systems
that can significantly affect the variations of physical properties; their petrophysical …

Suites of wireline well logs and three-dimensional (3D) seismic data were integrated to
characterise the reservoir and estimate the hydrocarbon in Otigwe field, coastal swamp …

Understanding the physical flow mechanisms in aquifer systems is essential in effectively

深层碳酸盐岩往往具有孔隙度低, 孔隙形态复杂的特点. 传统孔隙度反演方法仅考虑孔隙空间
大小对地层岩石物性的影响, 未考虑孔隙形态对岩石弹性特征的作用, 在反演深层碳酸盐岩孔隙 …

Formation evaluation techniques are the key to understand subsurface rocks properties from
well-logs, especially those drilled in hydrocarbon exploration wells. Knowledge of the …

The petrophysical evaluation of the Zubair Formation's Middle Shale member (4th Pay) in
the South Rumaila oil field has been conducted to characterize the reservoir and quantify its …

Estimation of total porosity from neutron and density porosity logs in organic shale (source
rock) is challenging because these logs are substantially affected by fluid and matrix …

ABSTRACT A recently introduced interpretation workflow has confirmed that inversion-
based interpretation is more reliable than conventional well-log analysis in high-angle (HA) …

When performing a cooperative inversion using a structural constraint, extracting an
accurate average direction from the high-resolution model is important because two models …

The paper suggests methods for determining the basic parameters of ordinary and
