NEDO has developed MEPAS, a software for exploration of geothermal reservoir. MEPAS has bcen developed as a tool for geologists to analyze earthquakes and find fractures by comparing earthquakes with other exploration data. MEPAS consists of a seismic data processing part and a geological analysis part. The geological analysis part features 3D display, time and space distribution display, fract...

  Diffusivity equation commonly used for pressure distribution prediction in porous media results from substituting equation of state and continuity equation in Navier-Stokes momentum equation. From mathematical point of view this equation format shows infinite propagation speed for pressure pulse through porous media, which is physically impossible. This issue may caused by numerous assumption...

stimulated wells completed in commingled reservoirs, i.e., This paper examines tic transient pressure response from slug reservoirs in which the layers communicate only at the wellbore tests in wells completed in multiple, hy&aulically fractured coal and not in the fractures or reservoir. Under these conditions, our seams. We developed a model for stimulated wells producing model is applicablee...

Abstract Two fluid regions are usually created during either water or polymer injection into an oil reservoir for enhanced recovery. The two create a composite system that requires analytical solution can be used to evaluate the performance. In this study, we present 2-D non-Newtonian in inner zone coupled with infinite boundary outer using power law model. Newtonian non-Newtonian. Moreover, ma...

In magnetization dynamics, the Gilbert damping α is often taken as a parameter. We report on a theoretical investigation of α, taking into account crystal symmetries, spin–orbit coupling and thermal reservoirs. The tensor α is calculated within the Kamberský breathing Fermi-surface model. The computations are performed within a tight-binding electronic structure approach for the bulk and semi-i...

Semiconductor nanowires are possible candidates to replace the metal-oxide-semiconductor field-effect transistors (MOSFET) since they can act both as active devices or as device connectors. In this article, the transmission coefficients of Si and GaAs nanowires with arbitrary transport directions and cross sections are simulated in the nearestneighbor sp3d5s∗ semi-empirical tight-binding method...

Well testing is of great importance in petroleum engineering, to have a kind of firsthand knowledge and estimating formation permeability, wellbore damage/ skin, etc. These parameters are further required to estimate production rate from a well and at the same time gives an idea of its productivity. These reservoir related parameters calculation is strongly dependent on formation thickness. Any...
