Abstract: 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.

Abstract: HOE 89/F 900 of the disclosure A process for stimulating oil and gas wells in oil and gas production from subterranean formations, and stimulant for this purpose In the process described, the oil/gas-containing subterranean formations are contacted with a selected fluorosurfactant as a stimulant. A particularly preferred stimulant is composed essentially of the said fluorosurfactants and of non-fluorinated nonionic surfactants from the group comprising the alkoxypolyethylene glycol ethers and from the group comprising the alkylphenoxypolyethylene glycol ethers, the three components being present in a weight ratio of preferably about 1 : 1 : 1.
