Compounds and method for enhanced oil recovery using sulfur surfactants |
| abstract |
A method of enhanced oil recovery wherein: (a) a flooding composition is delivered into a subterranean reservoir; (b) the flooding composition includes a sulfur surfactant; and (c) the fluid produced from the subterranean reservoir can also be analyzed to determine if the surfactant is present in the fluid. The surfactant preferably includes a sulfonate moiety or other sulfur-containing moiety. The presence of the surfactant in the fluid produced from the subterranean reservoir is preferably determined by X-ray fluorescence spectroscopy, HPLC-AES, or HPLC-ICP. |
