The Method for Oil-Water Identification in Tight Sandstone Reservoirs Based on Nuclear Magnetic Resonance and Micro-Differential Resistivity Logging

Cejing jishu
The tight oil reservoirs are characterized by low porosity and low permeability, which leads to significant errors in oil–water identification when using traditional resistivity models.

Impact of clay minerals on oil displacement efficiency in tight oil reservoirs

Arabian Journal of Chemistry
Although water and gas drives are still the most commonly used methods for most reservoirs, the high clay content adversely affects production efficiency. This study investigates three development methods (water, CO 2 , and N 2 ) in high-clay reservoirs.
