Karydas, A

A method is described for increasing steam mediated oil production using a steam injection recovery process, with one, two or more wells, which comprises: contacting a deposit containing crude oil or containing a crude oil generating material with an effective amount of a fluorochemical of formula ((R/sub f/)/sub n/(R')/sub p/)/sub m/Z. Each R/sub f/ is independently a straight or branched chain perfluoroalkyl, perfluoroalkoxy-perfluoroalkyl, omega-hydroperfluoroalkyl or perfluoroalkenyl, each R/sub f/ independently having 4 to 20 carbon atoms, n is 1, 2 or 3, p is 0 or 1, m is an integer from 1 to 5000, and R' is a direct bond when p is 0 or is an organic group having a valency of ntl and is covalently bonded to both R/sub f/ and Z.
