Abstract
A series of experimental floods at a range of mobility ratio which generates new data for unstable displacement processes is presented. These data are presented up to 100% recovery and included the following: effluent concentrations and recovery profiles, in situ visualization of the flow patterns, and measurement of the pressure field. The measurement of the pressure field is particularly novel and the information can be utilized to assess averaged models of viscous instability. A high accuracy numerical method is proposed to simulate the experimental five-spot stable and unstable displacements. The simulation reproduces the effluent concentrations, recovery performances and pressure drops, and also matches the main features of finger evolution.
