... dynamics. Important effects e.g. surfactants, and geometrical confinement, present in practical applications, are also accounted for. An example of our building blocks work at Birmingham, at the m-mm scale, has shown that interface breakup and satellite formation (see Figure 1 [7]) depend strongly...

... of the methods to postpone the onset of liquid loading to later in the field life of the reservoir (i.e. to a lower reservoir pressure) is to inject surfactants at the bottom of the well. These surfactants have two effects: they cause the surface tension between the gas and the water to drop (to around 30 mN/m...
