With "may". the chances are probably less than 50:50. With "may well" the chances are usually 60:40 or higher that it will happen. But note "probably" and "usually" - there is no certainty about the chances expressed in either of those expressions.

Most people would not include "well"

"May well" is a little more positive. If "may happen" is a 50% chance, "may well happen" is somewhat higher.

"May happen" is less certain, 50% or less. "May well happen" gives it a slightly better chance of happening, over 50%.

"Well" puts a suggestion of positivity on an outcome, but otherwise has no meaning.
