Zusammenfassung:	In the process described, the oil/gas-containing subterranean formations are contacted with a selected fluoro-surfactant as a stimulant. A particularly preferred stimulant consists essentially of the said fluoro-surfactants and of non-fluorinated, nonionic surfactants from the group of the alkoxypolyethylene glycol ethers and from the group of the alkylphenoxypolyethylene glycol ethers, the three components being present in a weight ratio of preferably about 1:1:1.
