摘要： Testing scale buildup in a well tool can include pressurizing separate cationic and anionic solutions, then heating the separate solutions, mixing together the solutions, and exposing the well tool to the mixed solutions. A well tool can be constructed by a) determining velocities of flow at a predetermined offset from surfaces of a geometric model representative of the well tool, b) calculating scale buildup on the surfaces based at least in part on the velocities, c) reducing pressure change per unit distance along selected ones of the surfaces having greater than a predetermined level of scale buildup, and d) repeating steps a-c until all scale buildup is no greater than the predetermined level. A method of predicting scale buildup can include inputting a parameter indicative of flow through a well tool to a mathematical model, which determines a rate of scale buildup on a surface of the well tool.

摘要： Dimensionality reduction systems and methods facilitate visualization, understanding, and interpretation of high-dimensionality data sets, so long as the essential information of the data set is preserved during the dimensionality reduction process. In some of the disclosed embodiments, dimensionality reduction is accomplished using clustering, evolutionary computation of low-dimensionality coordinates for cluster kernels, particle swarm optimization of kernel positions, and training of neural networks based on the kernel mapping. The fitness function chosen for the evolutionary computation and particle swarm optimization is designed to preserve kernel distances and any other information deemed useful to the current application of the disclosed techniques, such as linear correlation with a variable that is to be predicted from future measurements. Various error measures are suitable and can be used.

摘要： A system for variably resisting flow of a fluid composition can include a flow passage and a set of one or more branch passages which intersect the flow passage, whereby a proportion of the composition diverted from the passage to the set of branch passages varies based on at least one of a) viscosity of the fluid composition, and b) velocity of the fluid composition in the flow passage. Another variable flow resistance system can include a flow path selection device that selects which of multiple flow paths a majority of fluid flows through from the device, based on a ratio of desired fluid to undesired fluid in the composition. Yet another variable flow resistance system can include a flow chamber, with a majority of the composition entering the chamber in a direction which changes based on a ratio of desired fluid to undesired fluid in the composition.
