Abstract: A workflow to optimize a fracturing fluid for injection into a subterranean formation is provided. The workflow comprises measurement of fundamental properties and characteristics of reservoir rock and fluid, their interaction with fracturing fluid, computer-based models and laboratory performance testing to select preferred fracturing base fluid and additives package for use in fracturing/re-fracturing stimulation of specific shale formations to enhance hydrocarbon recovery.

Abstract: The present disclosure refers to systems and methods for producing hydrogen among other products. In some embodiments the methods comprise sequentially conducting a cracking step in a fixed bed mode and conducting a flowing step in a fluidized bed mode. Such sequential processes may result in a number of advantages including, for example, regenerating the catalyst during the fluidized bed mode in a manner such that beneficial heat is generated for use in the endothermic cracking step.

Abstract: The present disclosure refers to systems and methods for efficiently converting a C1-C3 alkane such as natural gas to a liquid C2-C10 product and hydrogen. Generally, the process comprises flowing the C1-C3 alkane through a plurality of tubes within a vessel wherein the tubes house a catalyst for converting the C1-C3 alkane to the liquid C2-C10 product and hydrogen. The C1-C3 alkane is heated under suitable conditions to produce the liquid C2-C10 product and hydrogen. Advantageously, the C1-C3 alkane is heated by burning a fuel outside the tubes in fuel burning nozzles configured to transfer heat from the burning through the tubes.
