Investigation of CO2 Displacement Characteristics of Highly Water-Sensitive and Low-Permeability Oil Reservoirs: A Case Study of Block A in Eastern China
Highly water-sensitive, low-permeability reservoirs are difficult to develop by water flooding because clay activation and pore-throat plugging impair injectivity. This study combined X-ray diffraction, scanning electron microscopy, water-sensitivity tests, long-core CO2 flooding, and response surface methodology to in...
