I have never seen this suggestion but it is not unreasonable.
The use of lubricants to facilitate drilling is quite common.
The injection of lubricants to facilitate plate slippage is not
unreasonable. But it would be potentially hard and require concrete
activity over an extended area.
One also has to differentiate between "slip" faults and
"break" faults. Very different and not always clearly
separate. I would suggest that the lubricant approach
would work with slip faults. It would not work with break
faults. In (a) you are dealing with plates slipping past
each other; in (b) you are dealing with plates running into
each other such that the only way around is to snap one
of the plates. Very distinct phenomena.
