Abstract:
Fluids produced from a fractured subterranean formation may be monitored by pumping into the well a fracturing fluid which contains a tracer. The method may be used to monitor produced hydrocarbons as well as produced water. The tracer may also be used in a sand control, frac pack or acid fracturing operation. The tracer is a component of a composite where it may be immobilized within a matrix (such as an emulsion) or porous particulate, onto a support or compressed with a binder into a solid particulate. The tracer may be slowly released from the composite.

Claim (Index 13):
A method of monitoring the productivity of hydrocarbons from a sandstone or carbonate formation penetrated by a well, the method comprising:\n (a) contacting the formation with a slurry containing solid particulates and a pre-determined solid tracer and an acid, the pre-determined solid tracer being hydrocarbon soluble, water soluble or both hydrocarbon soluble and water soluble and further wherein the solid tracer is capable of being slowly solubilized into fluids produced from the well; (b) differentially etching the acidizing solution around the solid particulates, thereby creating conductive channels on the surface of the formation; and (c) removing produced fluids from the well containing solubilized tracer.
