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 1):
A sand control method for a wellbore penetrating a subterranean formation, comprising\n (a) introducing into the wellbore a slurry comprising a composite having an immobilized solid tracer which is either hydrocarbon soluble, water soluble or both water soluble and hydrocarbon soluble and further wherein the solid tracer is capable of being slowly solubilized into fluids produced from the well and wherein the composite either comprises:\n (i) the tracer adsorbed onto a water-insoluble adsorbent, the water-insoluble adsorbent having a surface area between from about 1 m 2 /g to about 100 m 2 /g; \n (ii) the tracer absorbed into the pores of a porous particulate; \n (iii) the tracer adsorbed onto a calcined porous metal oxide substrate, the surface area of the calcined porous metal oxide substrate being between from about 1 m 2 /g to about 10 m 2 /g and the diameter of the calcined porous metal oxide substrate being between from about 0.1 to about 3 mm; or \n (iv) a microemulsion comprising the tracer and an emulsified solvent-surfactant blend wherein the particle size of the tracer in the microemulsion is between from about 0.001 microns to about 100 microns; \n (b) placing the slurry adjacent the subterranean formation to form a fluid-permeable pack capable of reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore; and (c) slowly solubilizing the solid tracer into fluids produced from the well.
