| titleOfInvention | Methods of assessing oil field saturation through use of reactive partitioning tracers |
| abstract | A family of organic tracers is proposed for single well chemical tracer tests, for example for the measurement of residual oil in petroleum reservoirs. The tracers consist of at least one ester of (hydroxyalkyl) benzoic acid of formula (I), wherein at least one of R 1 to R 5 is a hydroxy alkyl group —R 7 —OH and each of the remaining R 1 to R 5 groups is independently selected from H, F, Cl, Br, I, CF 3 CF 2 Cl, CFCl 2 , CCl 3 and at least one of these remaining R 1 to R 5 groups is not H, R 6 is selected from CH 3 , C 2 H 5 , C 3 H 7 , C 4 H 9 , CF 3 , CH 2 CF 3 , CCl 3 , CH 2 CCl 3 , CH 2 CHCl 2 , CH 2 CH 2 Cl, CH 2 CF 3 , CH 2 CHF 2 , CH 2 CH 2 F, CH 2 CH 2 CH 2 F, CH 2 CH 2 CHF 2 , CH 2 CH 2 CF 3 , CH 2 CH 2 CH 2 Cl, CH 2 CH 2 CH—Cl 2 , CH 2 CH 2 CCl 3 , C 3 H 6 F, C 3 H 5 F 2 , C 3 H 4 F 3 , C 3 H 6 Cl, C 3 H 5 Cl 2 , C 3 H 5 Cl 3 or a halogenated (hydroxymethyl)phenol and R 7 is selected from CH 2 , C 2 H 4 , C 3 H 6 , C 4 H 8 . |
