Patent ID: 11905813

Abstract:
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.
