>It's also nice that Exxon taking this Global revolution to Hungary :)

Too bad they didn't mention that in the article. In any case, it's nice to know that North American frac technology sometimes seems to work better than expected in Europe.

Exxon doesn't have much to say about their Germany operations, but I found this in Schlumberger's Q3 2008 report:

In Germany, Schlumberger teamed up with ExxonMobil Production Deutschland GmbH (Germany), the operator for MEEG (100% ExxonMobil-owned affiliate) and BEB (a 50%-50% joint venture between Shell and ExxonMobil) to further develop their tight gas reserves through the use of fracture stimulation.A well targeting a Carboniferous formation was fractured using ThermaFOAM* CO2 fracture fluid system in an attempt to drastically reduce fracture damage.The resulting treatment reduced the amount of water injected by 60% and reduced the overall amount of gel injected by 70% when compared to traditional treatments.The initial post-fracture gas rate was approximately 13 MMscf/d, an increase of over 2 times the rate predicted.
