How Hydrocarbons Break Out Of Oil Base Mud vs Water Base Mud

Does anyone have any information on how gas reacts with oil base mud compared to water base mud in terms of deliverability, absorption, and release at surface.  Any differences in molecular phase changes vs depth of the hydrocarbons from pressure and temperature.  It seems everyone agrees there is a difference, especially how gas breaks out at surface, but no one seems to know just why.

Thanks a lot..much to pour over but very enlightening

I am not an engineer, but have experienced the tendency of gas to go into solution in an oil base mud, especially in deep wells.  When it comes out of solution, it is near the shallower section of the hole, where the expansion can be very sudden.
