example

[0195] In the following examples, MeFBSEA was prepared according to the method of Parts A and B of Example 2 of U.S. Patent No. 6,664,354 (Savu), except that 4270 kilograms (kg) of N-methylperfluorobutanesulfonamide ethanol, 1.6 kg phenothiazine, 2.7 kg methoxyhydroquinone, 1590 kg heptane, 1030 kg acrylic acid, 89 kg methanesulfonic acid (in place of trifluoromethanesulfonic acid) and 7590 kg water (in part B).

[0196] In the following examples, 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl acrylate (FOA) was prepared according to the following method. Add 100 g (0.275 mol) of 1H,1H,2H,2H-perfluorooct-1-ol (C 6 f 13 C 2 h 4 OH) (available from Clariant Chemical Co. (Mount Holly, NC) under the trade designation "FLUOWETEA 600"), 19.8 grams (0.275 moles) of acrylic acid (available from Sigma-Aldrich (St. Louis, MO)), 250 grams of heptane, and 1 gram of methane sulfonic acid, and the mixture was heated to reflux for 15 hours. Water (approximately 4.9 to 5 grams) was collect...

example 6 and 7

[0204] The preparation of Examples 6 and 7 was carried out according to the method of Examples 1 to 5, except that 30 grams of solvent mixture was used, the amounts of reagents used and the molar and weight ratios are given in Table 3 below.

Abstract

The present invention discloses a fluorinated polymer having a first divalent unit independently represented by formula (I): or formula (II) and a second divalent unit containing a quaternary ammonium group. Compositions comprising fluorinated polymers and solvents, methods of treating hydrocarbon-bearing formations using these compositions, and fluorinated polymer-treated articles are disclosed. Also disclosed are methods of making compositions containing fluorinated polymers.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 61 / 081826, filed July 18, 2008, the contents of which are incorporated herein by reference. Background technique [0003] In the oil and gas industry, certain surfactants, including certain fluorinated surfactants, are known fluid additives for various downhole operations such as fracturing, water injection and drilling. Typically, these surfactants act to lower the surface tension of the fluid or to stabilize the foaming fluid. [0004] Some hydrocarbons and fluorine-containing compounds have been used to modify the wettability of reservoir rocks, which can be used, for example, to avoid or remedy water plugging (eg, in oil or gas wells) near the wellbore (ie, in the region near the wellbore) or liquid Hydrocarbon accumulation (eg, in gas wells). Water plugging and liquid hydrocarbon accumulation may be caused by natural phenomena (eg, water-be...
