A tracer solution suitable for use in measuring flow velocities in a borehole, includes: a) a gadolinium salt of a carboxylic acid of general formula Image where R is an alkyl of not less than four carbon atoms, typically C4 or C5 alkyl, and R1 and R2 are hydrogen or an alkyl group, typically hydrogen, methyl or ethyl; b) a free branched-chain carboxylic acid such as an excess of the acid used to form the Gd salt; and c) a non-polar solvent such as hexane or heptane. The Gd content of the solution should be not less than about 50 g/l and is best when it is as high as possible, for example greater than 100 g/l, and the viscosity should be less than 20 cP.
