... the unswept oil zones/areas. In addition, the permeability of each core before and after treatment was measured to confirm whether or not the PPG damaged the cores. The effect of PPG particle size, rock permeability, and brine concentration on core damage was investigated. Results of these filtration test...

... Abstract There is a potential for improving the reliability of standard core tests for seismic monitoring studies. A primary concern is to quantify and correct for core damage effects, which significantly enhance the stress dependency of wave velocities. Careful laboratory procedures...
