    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.

    Abstract: An organotemplate-free synthetic process for synthesizing an aluminosilicate molecular sieve SSZ-122 is provided. The process includes (1) preparing a reaction mixture comprising: (a) a silicon atom source; (b) an aluminum atom source; (c) a source of an alkali metal [M]; (d) a source of hydroxide ions; (e) water; and (f) seed crystals; and (2) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the aluminosilicate molecular sieve.

    Abstract: Disclosed are systems and methods for detecting the erosion and corrosion effects of solids during oil and/or gas production. An erosion corrosion detector (BCD) is positioned in fluid communication with a pipe in a production facility such that a sensor element of the BCD contacts at least a partial stream of produced fluid in the pipe. Changes in one or more physical measurement of the BCD and/or changes in pressure drop across the sensor element are monitored over time. The changes are interpreted to identify whether there is loss of materials (e.g., metal) in the production facility, quantify of this loss, and determine the mechanisms through which this loss is occurring. A control system can receive the change in the physical measurement and/or the pressure drop over time as input into a control strategy for controlling a well control valve to control a rate of production of well fluids.
