Seismic data are recorded and commonly interpreted in vertical two-way time; well logs, measured in depth, must be tied to seismic using a time-depth curve. However, well ties contain a large amount of uncertainty due to errors in the generation of synthetic seismograms and manual matching of synthetic seismograms to seismic traces. Using dynamic time warping, a fast algorithm that optimally al...

Abstract Carbonate reservoirs in Iran are the most important and main sources of oil gas production. Hydrocarbon flow rates from carbonate heavily rely on development natural fractures. This study focuses role fractures reservoir quality considering Sarvak (southwest Iran) as second Iran. To identify small-scale around borehole walls, cores description image logs were utilized. Due to high cost...

Purpose. The research is aimed at evaluating the petrophysical characteristics of Late Cretaceous Matulla Formation in central part Gulf Suez order to detect its hydrocarbon reservoir potential. Methods. Well logs from five wells (Muzhil-1, -2, -4, -7, -8) were used evaluate reservoirs based on a computerized approach. Petrophysical parameters and fluid types calculated, verified using core dat...

Abstract Underground CO 2 storage is a promising technology for mitigating climate change. In this vein, the subsurface condition was inherited lot of uncertainties that prevent success project. Therefore, study aims to build 3D model under geological enhancing capacity in Shahejie Formation (Es1), Nv32 block, China. The well logs, seismic data, and data were used construction 3-D petrophysical...

Abstract The Coniacian–Santonian Matulla Formation is one of the important reservoirs in July oilfield, Gulf Suez Basin. However, this formation characterized by uncertainty due to complexity reservoir architecture, various lithologies, lateral facies variations and heterogeneous quality. These challenges, turn, affect effectiveness further exploitation along In work, we conduct an integrated s...

This paper proposes a two-step approach for characterizing the reservoir properties of the world’s largest non-associated gas reservoir. This approach integrates geological and petrophysical data and compares them with the field performance analysis to achieve a practical electrofacies clustering. Porosity and permeability prediction is done on the basis of linear functions, succeeding the elec...

DT log is one of the most frequently used wireline logs to determine compression wave velocity. This log is commonly used to gain insight into the elastic and petrophysical parameters of reservoir rocks. Acquisition of DT log is, however, a very expensive and time consuming task. Thus prediction of this log by any means can be a great help by decreasing the amount of money that needs to be allo...

This study focuses on the geological model of sandstone formations and petrophysical characterization hydrocarbon reservoirs in Termit Basin. The specific objectives are: (1) to establish a visualizing geometry reservoir rocks (2) visualize spatial vertical distribution parameters (porosity, permeability). methodological approach integrated interpretation lithology data petrographic from logs b...

Well log correlation is an important step in geophysical interpretation, but as the number of wells increases, so does the complexity of the correlation process. We propose a new method for automatic and simultaneous well log correlation that provides a globally optimal alignment of all logs, and in addition, is relatively insensitive to large measurement errors common in well logs. First, for ...
