A method of treating a multi-zoned subterranean formation with composites having well treatment agents is disclosed. The well treatment agent treated in each zone is distinguishable. At least a portion of the well treatment agent is released from one of the composites into the well or formation. The formation of undesirable contaminants may be inhibited or prevented in the well or in the formation by the release of the well treatment agent from one or more of the composites. The well treatment agent also serves as a tracer. When fluid transported from the formation or well is collected, the source of the transported fluid may be determined by comparing a chemical or physical parameter of the well treatment agent with a working set of known taggants.

Method of monitoring fluid flow from a reservoir using well treatment agents

Scales are prevented or inhibited from forming in a well or in a formation penetrated by a well by pumping into the well a fluid comprising a hydratable polymer, a crosslinking agent, such as an organometallic crosslinking agent containing a polyvalent metal and a scale inhibitor selected from the group consisting of polyvinyl sulfonates, a polyacrylamidomethylpropane sulfonic acid, carboxymethyl inulin and sulfonated polyacrylates and mixtures thereof.

Method for enhancing productivity of hydrocarbon formations using fluid containing organometallic crosslinking agent and scale inhibitor

This invention provides a composition and a method of using a composition containing an imidazoline, optionally containing a paraffin inhibitor, for improving the pour point of liquid hydrocarbons, such as crude oil and petroleum fuel, and/or inhibiting or reducing the formation of paraffin deposits in such liquids.
