HYDRAULIC FRACTURING WITH DENSITY-TUNABLE HEAVY FRACTURING FLUIDS
A slurry including a density-tunable heavy fracturing fluid and a method for completing a hydrocarbon well using such a slurry are provided herein. The slurry includes a proppant and the density-tunable heavy fracturing fluid, where the density-tunable heavy fracturing fluid includes a pseudo heavy fluid suspension, a concentrated aqueous solution of a soluble heavy compound, and/or a high-density organic solution. The density of the density-tunable heavy fracturing fluid is between 1.25 grams/milliliter (g/ml) and 3.4 g/ml. Moreover, the density of the density-tunable heavy fracturing fluid is selected based on the density of the proppant. According to the method provided herein, the slurry is used to provide for more effective placement of the proppant within the fractures than can be achieved using only a slurry including conventional fracturing fluid and the proppant.

DOWNHOLE RESIN COATINGS COMPRISING A CARBON NANOMATERIAL AND METHODS ASSOCIATED THEREWITH
Resin coatings are frequently formed in conjunction with performing a subterranean treatment operation. However, poor thermal conductivity and mechanical strength of resin coatings can be problematic in a downhole environment and eventually lead to their breakdown. Methods for enhancing a resin coating in a downhole environment can comprise: introducing a treatment fluid comprising a curable resin and a carbon nanomaterial into a wellbore penetrating a subterranean formation; forming a coating of the curable resin on a surface in the wellbore, the carbon nanomaterial being dispersed throughout the coating; and curing the curable resin to form a cured resin coating.

POLYACRYLAMIDE SLURRY FOR FRACTURING FLUIDS
The present disclosure relates to fracturing fluids that use friction reducers. The composition of the present disclosure is a slurry comprising a water-soluble polymer suspended in an oil-based vehicle with the aid of a suspension agent and a surfactant. Specifically, the water-soluble polymer is polyacrylamide and the oil-based vehicle is petroleum distillate. The surfactant is an ethoxylated nonionic emulsifier. The surfactant can be a fatty chain EO/PO (ethylene oxide propylene oxide) and/or oxylated propoxy copolymer. The suspension aid is any variation of diblock copolymers based on styrene and ethylene/propylene. The composition may also contain a dispersant such as organophilic clay or a synthetic alternative as the suspension agent.
