Abstract: Methods for assessing the effectiveness of an acid stimulation operation in a hydrocarbon well are described herein. The methods use encapsulated tracer particles comprising a tracer material that is coated with a calcium carbonate shell. Different encapsulated tracer particles are placed into different portions of a well. A subsequent acid stimulation operation dissolves the calcium carbonate shell and releases the tracer material. The different tracer materials indicate the effectiveness of the acid stimulation operation in different portions of the well.

Abstract: The present application pertains to a method of tracing acid stimulation treatment in a hydrocarbon well using one or more coated tracers. The method comprises placing the one or more coated tracers at pre-determined downhole locations in the hydrocarbon well. The well is then acid stimulated and the amount of the tracer in a produced fluid from the hydrocarbon well is measured. The one or more coated tracers each comprise a tracer and a coating which are described herein.

Abstract: A deployment system for deploying a polymer grout system includes a first conduit line for conveying an isocyanate component, a second conduit line for conveying an organic polyol component, and a mixer for mixing the isocyanate component and the organic polyol component to form an expandable polymer grout system that is deployed to a target location associated with a wellbore. The deployment system can include a tailpipe and/or bridge plug for directing the expandable polymer grout system to the target location. The disclosure also includes methods of using the foregoing deployment system.

Abstract: A method includes placing a treatment fluid including a crosslinked gel in a wellbore penetrating a subterranean formation, the crosslinked gel including a gelling agent and a borate crosslinking agent, de-crosslinking a portion of the crosslinked gel, the de-crosslinking induced by a sufficient change in operating pressure, the de-crosslinking providing a release of active sites on the borate crosslinking agent and reducing the viscosity of the treatment fluid, and providing a borate-affinity agent to capture the released active sites on the borate crosslinking agent. A fracturing fluid includes a gelling agent, a borate crosslinking agent, a latent borate-affinity agent, and a proppant.

Abstract: A method of deploying an expandable composition in a cement top job in a well system includes identifying evidence of actual or potential gas migration within an annulus cement of the well system. Once the evidence of gas migration is identified, a first component and a second component are mixed in a mixer to form the expandable composition and the expandable composition is pumped from the mixer through a conduit to a top of cement of the annulus cement. The expandable composition expands to form an expanded composition that seals the annulus above the top of cement of the annulus cement. Cement can be added onto the expanded composition.
