Abstract: A method for monitoring gas production in a subterranean formation includes introducing a polymer composite particle having a degradable portion and a non-degradable portion including a tracer into a stimulation fluid and injecting the stimulation fluid into the subterranean formation to a treatment stage of a treatment zone. The treatment stage has at least one opening that the polymer composite particle may flow into and remain inside. The polymer composite particle may be exposed to moisture at a downhole temperature while inside the at least one opening. The moisture may degrade the degradable portion of the polymer composite particle, thereby releasing the non-degradable portion including the tracer. Produced gas that includes the non-degradable portion including the tracer may be recovered from the subterranean formation and the tracer may be correlated to the treatment stage of the treatment zone of the subterranean formation.

Abstract: Described is a polymer-based well tracer. The polymer-based well tracer is a fluoropolymer having a fluorinated group. The fluoropolymer may be formed into a particle, a coating for proppant particulates, or encapsulated in a polymeric resin. Upon degradation or hydrolysis of the fluoropolymer, the fluorinated group having a fluorinated compound is released within the well.

Abstract: Acidizing treatments for carbonate reservoir may include a surfactant comprising one or more of C8-C30-alkyloxyglycoside-substituted hydroxysultaine, C8-C30-alkylamidopropyl hydroxysulfobetaine, poly(diallyldimethylammonium chloride), C8-C30-alkyl amido alkylamine oxide, C8-C30-alkyl-amido amine oxide, C8-C30-alkyl amine oxide, C8-C30-alkyl aryl amine oxide, C8-C30-alkyl polyether phosphate, C8-C30-alkyl polyether phosphonate, C8-C30-alkyl ether phosphonate, C8-C30-alkyl amido ammonium propyl sulfonate, C8-C30-alkyl amido ammonium vinyl sulfonate, C8-C30-alkyl ether sulfonate, C8-C30-alkyl amido ammonium propyl sulfonate, C8-C30-alkyl ether sulfonate, alpha olefin sulfonate, C8-C30-alkyl benzene sulfonate, C8-C30-alkyl ethoxy carboxylate, C8-C30-alkylphenol ethoxylate carboxylate, and C8-C30-alkyl amido ammonium carboxylate. These acidizing treatments may also include an aqueous acid solution or mixture. In these acidizing treatments, the surfactant may be configured to partially or fully adsorb on a carbonate formation to retard the partial dissolution of the formation. Corresponding methods of reducing the reactivity of acidizing treatment may include introducing these acidizing treatments into wellbores such that the acidizing treatments contact carbonate formations.

Abstract: Methods for producing proppant with nanoparticle proppant coating are provided. The methods include coating the proppant particles with a strengthening agent, functionalized nanoparticles, and unfunctionalized organic resin to produce proppant with nanoparticle proppant coating. Additionally, a proppant comprising a proppant particle and a nanoparticle proppant coating is provided. The nanoparticle proppant coating includes a strengthening agent, functionalized nanoparticles, and unfunctionalized organic resin. The nanoparticle proppant coating coats the proppant particle. Additionally, a method for increasing a rate of hydrocarbon production from a subsurface formation through the use of the proppant is provided.

Abstract: A method includes introducing a fluoro-based small molecule tracer into a stimulation fluid, injecting the stimulation fluid into a target zone of a subterranean formation, and maintaining the fluoro-based small molecule tracer inside the target zone of the subterranean formation for an amount of time. While being maintained inside the target zone, the fluoro-based small molecule tracer comes into contact with water at a downhole temperature resulting in hydrolysis of the fluoro-based small molecule tracer to produce a fluorinated tracer and a nonfluorinated group. Then, produced fluid that includes the fluorinated tracer is recovered, a concentration of the fluorinated tracer in the hydrocarbons is determined, and the concentration of the fluorinated tracer is correlated to a productivity of the target zone of the subterranean formation.
