.... The maximum relative error does not exceed 9.52%, indicating that the established mathematical model of pressure change is in good agreement with the test results, and the established mathematical model has high accuracy. Based on the positive pressure decay method, an experimental bench for leak detection...

... into horizontal well, pump pressure and passing capacity of the magnetic source generator in the curved section need to be analyzed. So, a mathematical model of tripping in the magnetic generator is established. If curvature radius, deviation angle, and friction factor are known, the forces acting on the magnetic...

...Wuguang Li; Zhang Jian; Xiaokai Chen; Hao Chen Gas content is one of the most important parameters of shale reservoir evaluation and productivity evaluation. In order to obtain gas content accurately, based on the first law of Fick and material balance equation, mathematical model of gas dispersion...

... and unsteady-state conditions. Accordingly, this review will discuss nanoparticle transport phenomena in porous media with its focus on the filtration mechanisms, the underlying interaction forces, and factors dominating nanoparticle transport behavior in porous media. Finally, mathematical models used...

... in relatively slow impedance growth. A risk analysis employing probabilistic histograms of injectivity damage parameters is used to well behavior prediction under high uncertainty conditions. (1) Both coreflood test and mathematical modeling on well injectivity performance show that the impedance growth...

... fuels ( 850 ° C ) . With reference to the above, the aim of this paper is to develop a model of the FBC reactor that focuses mainly on the fate of the rising endogenous bubble. To this end, the mathematical model takes full advantage of a detailed chemical kinetic scheme ( 9 ), which includes...
