Comparison of Oil Displacement by Water Between Naturally Fractured Reservoir and Vuggy Fractured Reservoir Based on Streamline Technique

, 2010
The differences between naturally fractured reservoir and vuggy fractured reservoir are apparent in the aspect of oil displacement by water. In fractured reservoir, the oil displacement by water is the governing recovery mechanism known as capillary ...

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Multi‐Source Hydrogeological Investigation, Water Inflow Prediction, and Water–Mud Inrush Risk Zoning for a Strongly Karstified Limestone Tunnel: A Case Study of the Dongyang Tunnel

Engineering Reports, Volume 8, Issue 10, October 2026.
Multi‐source hydrogeological investigation identified widespread karst cavities and water‐bearing fractured zones along the Dongyang Tunnel. Comparative inflow prediction yielded a conservative design control value of 1557.61 m3/day, supporting section‐specific water–mud inrush zoning and targeted drilling, grouting, controlled drainage, and ...
