Gas movement in otherwise water‐saturated porous media is complex and is important for a variety of applications. The interplay of gravity, capillary, and viscous forces influences the movement and resulting pattern of gas. To develop a better understanding of this competition among these forces, air injection experiments were performed in an intermediate‐scale, two‐dimensional flow cell at injection rates of 0.1, 10, 100, 250, and 498 mL min−1. The resulting gas patterns were characterized using gas pressure measurements and optical density measurements based on digital images to classify gas flow as continuous, transitional, or discontinuous, and near‐pore‐scale observations of tran...
