Experimental and Numerical Modeling Studies of Viscous Unstable Displacement

Experimental studies of fluid flow at adverse mobility ratio have quantified the development of viscous<br>fingers. CIPR have developed an experimental set up for 2-D in-situ saturation measurements. The X-ray<br>scanner can quantify saturations over a large 2-D area and can also image saturation changes of up to 1 x 1<br>m rock slabs. The 2-D scanner is designed specifically to study viscous unstable displacements for both<br>miscible and immiscible processes.
