Electro-facies classification based on core and well-log data

Journal of Petroleum Exploration and Production Technology, 2023
Facies studies represent a key element of reservoir characterization. In practice, this can be done by making use of core and petrophysical data. The high cost and difficulties of drilling and coring operations coupled with the time-intensive nature of ...

A multi-scale approach to determine the REV in complex carbonate rocks [PDF]

, 2013
Complex porous carbonates display heterogeneity at different scales, influencing their reservoir properties (e.g. porosity) especially since different porosity types may exist on different spatial scales.

Characteristics of Lacustrine Diamictite and Analysis of Diagenetic Reservoir Facies in the Neogene Lower Youshashan Formation in the Dafengshan Tectonic Belt in the Qaidam Basin

Energy Science &Engineering, Volume 14, Issue 4, Page 1976-1989, April 2026.
Based on field outcrop data, core descriptions, comprehensive thin section data (plain, cast, and fluorescent), scanning electron microscopy, whole rock analysis via X‐ray diffraction, physical property tests, element logging, core recording, and oil pilot tests, we propose utilizing a mature and practical three component classification method for ...

The Methods of Determination of Stratigraphic Boundaries and Reservoir Units for the Yamama Formation in the Ratawi Oil Field, Southern Iraq

Iraqi Geological Journal, 2023
The qualitative interpretation of the logs was used by interpreting the behaviour of their curves to determine the upper and lower boundaries of the Yamama Formation in the Ratawi Oil Field, southern Iraq, and their reservoir units for the wells

Appraising Carbon Geological‐Storage Potential in Saline Aquifers Using Two‐Phase Rate‐Transient Analysis

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Rate transient analysis (RTA) is a practical and cost‐effective method for CO2 injection data analysis and storage capacity evaluation of saline aquifers. However, the nonlinear behavior introduced by two‐phase CO2–brine flow, coupled with pressure‐dependent fluid and rock properties, significantly limits the applicability of conventional ...
