Abstract:
A method of monitoring a parameter of a hydrocarbon well, pipeline or formation is provided. The method comprises introducing a tracer into the hydrocarbon well, pipeline or formation; producing a fluid from the hydrocarbon well, pipeline or formation; and analysing the fluid to determine if the tracer is present in the fluid. The tracer comprises a halogenated alkoxylated-benzoic acid, an alkoxylated benzene sulfonic acid, a salt of a halogenated alkoxylated-benzoic acid or a salt of an alkoxylated benzene sulfonic acid.

Claim (Index 4):
The method according to  claim 1 , wherein the tracer comprises a compound, or a salt thereof, of formula 1: wherein R 1  is selected from the group consisting of C n F x Cl y H (2n+1\u2212x\u2212y)  where n=1, 2 or 3, and x and y are integers such that 0\u2264x+y\u22642n+1, wherein at least one of R 2 , R 3 , R 4 , R 5  and R 6  is carboxylic acid or sulfonic acid, wherein the remainder of R 2 , R 3 , R 4 , R 5  and R 6  are selected from the group consisting of F, Cl, Br, H, B(OH) 2 , C m F j Cl k Br l H (2m+1\u2212j\u2212k\u2212l) , where m=1, 2 or 3, each of j, k and l are integers such that 0\u2264j+k+1\u22642m+1, and O\u2014C p F r Cl s Br t H (2p+1\u2212r\u2212s\u2212t) , where p=1, 2 or 3, and r, s and t are integers such that 0\u2264r+s+t\u22122p+1, and wherein either at least one of R 2 , R 3 , R 4 , R 5  and R 6  is sulfonic acid, or at least one of R 1 , R 2 , R 3 , R 4 , R 5  and R 6  is halogenated, or both.
