Abstract: Hydraulic fracturing pumps at a well pad comprising multiple wells can be separated into brine pumps and slurry pumps. A split stream barrier separates the brine pumps from the slurry pumps. At least one slurry barrier separates a first slurry pump and a second slurry pump. The split stream barrier and the slurry barrier allow maintenance to be performed on the first slurry pump while the second slurry pump and the brine pumps continue to operate.

Abstract: The present disclosure refers to systems and methods for remediating a produced water from an oil or gas well. A representative process may comprise optionally purifying and then electrolyzing the produced water to produce at least hydrogen and oxygen; storing, selling, releasing, or converting oxygen to a useful oxygen product; and storing, selling, releasing, or converting hydrogen to a useful hydrogen product and to produce fresh water for beneficial reuse. Alternatively or additionally, the optionally purified produced water may be subjected to steam reformation with methane to produce carbon dioxide and hydrogen which can be used as desired.

Abstract: Subsurface representations that define subsurface configurations in layer space are used to train a machine learning model. The trained machine learning model is used to generate synthetic subsurface representations in the layer space. The synthetic subsurface representations are generated to match one or more conditioning characteristics. Conditioning of the trained machine learning model is performed in latent space.

Abstract: A method of transferring at least one subterranean core sample from a retrieval vessel to a testing vessel can include removing at least one pressure barrier on the retrieval vessel using a linear actuator while maintaining a sampling pressure on the at least one subterranean core sample at which the at least one subterranean core sample is taken from a subterranean formation. The method can also include pressurizing the testing vessel to the sampling pressure using the linear actuator, and transferring the at least one subterranean core sample from the retrieval vessel to the testing vessel. The method can further include sealing the testing vessel with the at least one subterranean core sample at the sampling pressure, where the testing vessel allows the at least one subterranean core sample to be tested while the at least one subterranean core sample is maintained at the sampling pressure.

Abstract: Embodiments for generating a reservoir performance forecast are provided. The embodiments may be executed by a computer system. In one embodiment, a method includes obtaining inflow performance relationship data generated from a physics-based subsurface-surface coupled simulation model having a surface, a subsurface, and one or more wells fluidly connecting the subsurface to the surface. The inflow performance relationship data comprises performance data for at least one phase of fluid for each well. The method also includes generating a performance forecast for the reservoir using a subsurface simulator and a surface simulator. The subsurface simulator uses the inflow performance relationship data to represent the subsurface during generation of the performance forecast, and the performance forecast satisfies constraints solved by the surface simulator. In one embodiment, a method does not utilize a surface simulator.
