Core samples were cut from two Berea sandstone blocks for coreflooding images. The core samples were characterized using X-Ray Powder Diffraction (XRD), X-Ray Fluorescence (XRF), and Scanning Electron Microscopy (SEM) analyses. The coreflooding began by injecting a core sample with water having salinity values of 0, 10, 30, or 60 g/L NaCl.

15/03/2021With development dating from the 1800s, the Devonian Berea Sandstone has a long history of oil and gas development in the Appalachian Basin. A new phase of development began in northeastern Kentucky in 2011 with production of high-gravity oil from horizontal wells at depths less than 2200 ft (671 m).

1 Kozaki (2012) studied the possibility of combining low-salinity waterflooding and polymer flooding through core flooding in Berea sandstone samples. Results showed that injection of low-salinity polymer resulted in a 10% reduction in the residual oil saturation compared to high salinity waterflooding and that the maximum oil recovery was achieved with fewer pore
