摘要:
Colloidal coal-in-water slurries having nano-particles of coal creating a pseudo-fluid. The colloidal coal-in-water slurry generally includes from about fifty to about seventy two weight percent of coal, with about 20 to about 80 percent of the coal having a particle size of about one micron or less with a mode particle size of about 250 nanometers. The coal-in-water slurry can also include a surfactant system containing one surfactant or mixtures of two or more surfactants, or mixtures of one or more surfactants and an inorganic or organic salt. The coal-in-water slurry can be used in low NOx burner applications as the main fuel and/or the reburn fuel, in gasification processes as the input fuel either alone, or in combination with organic materials, in gas turbine applications, and in diesel engine applications.

Implementations that integrate data-driven modeling and knowledge into self-improving reasoning systems and processes are described. For example, an implementation of a method may include determining at least one recommended action using a reasoning component having a data-driven modeling portion and a knowledge-based portion. Such determining includes integrating one or more determination aspects determined by the data-driven modeling portion, and one or more additional determination aspects determined by the knowledge-based portion.
摘要:
The present invention relates to a process for restarting core flow with viscous oil after a long standstill period. The process comprises initiating a flow of low viscosity fluid such as water into an inlet portion of a pipeline; gradually increasing the flow of the low viscosity fluid until a desired steady state condition is reached and initiating a flow of viscous oil into the inlet portion of the pipeline after the steady state condition has been reached.

One or more computer-readable media include computer-executable instructions to instruct a computing system to receive simulation results for future behavior of a reservoir that includes a material production well and a fluid injection site; define a virtual sensor as being located between the material production well and the fluid injection site; determine fluid saturation at the virtual sensor based at least in part on the simulation results; and issue a notification if the fluid saturation at the virtual sensor exceeds a fluid saturation limit. Various other apparatuses, systems, methods, etc., are also disclosed.

摘要:
A process for transporting viscous oil in a pipeline is described which comprises placing a spherical sealed pig within the pipeline at a desired position; filling a fraction of the pipeline upstream of the pig with a low viscosity fluid such as water; and initiating core flow of a viscous oil such as a heavy or extra heavy crude oil after the first fraction has been filled. The process permits the core-flowed viscous oil to be transported in the same pipeline with a non-core-flowed fluid. To do this, a second pig is placed in the pipeline intermediate the core-flowed viscous oil and the non-core-flowed fluid and a second fraction of the pipeline intermediate the second pig and the core-flowed viscous oil batch is filled with a low viscosity fluid such as water.
