Abstract: A remote survey system includes an unmanned surface vehicle that includes a body, a propulsion system coupled to the body to provide mobility to the unmanned surface vehicle to traverse a surface of a waterbody, and a thickness detection assembly mounted to a hull of the body and including one or more thickness detection cameras. A central computer system is located at a command center and in wireless communication with the unmanned surface vehicle via a communication module. The one or more thickness detection cameras are positioned to obtain one or more images or videos of an air-oil-water interface on the surface of the waterbody, and a thickness of a released substance present on the surface of the waterbody is determined based on the one or more images or videos of the air-oil-water interface.

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.
