>So if water based fluids don't work, and oil based fluids are prohibited, that leaves synthetic fluid as the next choice.

Dr. Szabo did suggest this possiblility:

"The current concept is already working in America, so why would not work in our country – inferred György Szabó. Of course, the technological challenge continues to be extremely difficult. For example, fracturing the rocks is such a critical task, like the appropriate choice of liquid used in fracing, in our case it is very likely that instead of using the existing water-based liquids, we will be using synthetic material. György Szabó emphasized that the research continues to rely on the work by domestic research institutes and universities, and he wish to continue this practice."
