Claim 14:
15. A non-transitory computer-readable medium that includes wellbore-simulation software that is executable by a processing device for causing the processing device to:
simulate changes in gas dissolution of a gas in a liquid flowing from a downhole location to a well surface through a wellbore over the course of a plurality of time steps by:
dividing the wellbore into a plurality of segments spanning from the well surface to the downhole location, each segment spanning a respective depth increment between the well surface and the downhole location; and
for each time step of the plurality of time steps:
determining a respective multiphase-flow regime associated with each segment of the plurality of segments based on a simulated pressure level, a simulated temperature, a simulated pipe eccentricity, and a simulated fluid velocity at the segment; and
determining how much of the gas is dissolved in the liquid at each segment of the plurality of segments based on the respective multiphase-flow regime at the segment; and

generate a display based on the changes in the gas dissolution in the liquid over the plurality of time steps.
