The database of relaxation characteristics core samples from the parametric well was created. It includes their main petrophysical parameters, NMR signal and results its processing interpretation. A comparative analysis obtained data with lithological stratigraphic carried out. Using example a well, it is shown that can be used to quickly obtain information on distribution reservoir properties ...

In this paper, I introduce a new mathematical model of the IP effect based on the effective-medium theory, which provides a unified mathematical method to study heterogeneity, multi-phase structure, and polarizability of rocks. The geoelectrical parameters of a new composite conductivity model are determined by the intrinsic petrophysical and geometrical characteristics of composite media: mine...

The need to identify the major parameter with an overwhelming impact on estimated hydrocarbon volume has been a challenge for stakeholders in oil and gas industry. To address this challenge, investigation of depositional facies petrophysical parameters was carried out field located within Niger Delta using 3D geologic models. Different modeling techniques were employed study; each technique pro...

Tight oil reservoirs have been a concerned of the industry due to their substantial influence on production. Due poor permeability, numerous problems are encountered while producing from tight reservoirs. Petrophysical and geomechanical rock properties essential for understanding assessing fracability reservoirs, especially enhance permeability. In this study, Saadi B reservoir in Halfaya Iraqi...

Abstract The present work aims to investigate the reservoir characterizations of Lower Cenomanian Baharyia Formation by creating isoparametic maps calculate petrophysical parameters and detect favorable parts for oil accumulations using available well logging data. is one main hydrocarbon sandstone reservoirs in northern Western Desert Egypt. About 90% field produces form Formation. This has be...

Abstract Eocene Sokor-1 reservoir is intrinsically heterogeneous and characterized by low-contrast low-resistivity log responses in parts of the Termit subbasin. Discriminating lithology fluid properties using petrophysics alone complicated undermines characterization. Petrophysics rock physics were integrated through diagnostics (RPDs) modeling for detailed description microstructure quality P...
