System for delivery of a tracer in fluid transport systems and use thereof
First Claim
1. A tracer delivery system which comprises of a melamine formaldehyde resin (MFR) polymer wherein the polymer is doped with one or more tracers and the polymer releases tracer after placement in a liquid system;
- andwherein the amount of tracer is about 5-20% by weight based in the total weight of the system and wherein the doping of the polymer comprises of mixing the tracer with a MFR condensate solution comprising of melamine, formaldehyde, methanol and water prior to hardening the solution with a hardener.

Abstract
The present application describes a specific tracer delivery system that has been tested. The claimed system is composed of melamine formaldehyde resin (MFR) doped with various tracer materials. The MFR is used to slowly release tracer compounds into a liquid system. The MFR/tracer mixture is applied as part of a monitoring system where tracer is delivered from the MFR/tracer mixture at a specific location up-stream and detected at some location downstream, thereby verifying fluid flow from that specific location up-stream. The MFR can be doped with different types of tracers, thereby allowing placement of different tracers at several different positions upstream. Production from the various labelled zones can be verified through the analysis of one sample downstream.
