Successful exploitation of tight sandstone gas is one the important means to ensure “increasing reserves and production” oil initiative also ways national energy security. To further improve accuracy historical matching field data such as production bottom-hole pressure during process this type reservoir, in study, a new expression wellbore for uniform flow vertical fractured wells Laplace spac...

The functional architecture focuses on decomposing functionality into modules that offer certain features. These features require interactions in order to complete their functionality. However, functional architectures typically only focus on the static aspects of the system design. Additional modeling techniques, such as message sequence charts are often used in the early phases of software de...

This paper presents a mathematical model for transient flow of the non-Newtonian power-law fluid in double porous media and fractal reservoir. By using Douglas-Jones predictor-corrector method, we obtain the solution for the constant rate condition at a single well in an infinite reservoir. The flow behavior is also analyzed. Finally, we discuss the pressure response to the various parameters. ...

This paper describes analyses being performed to aid in the development of operation strategies for the Long Term Flow Test at the Hijiori Hot Dry Rock reservoir, Japan. Testing has shown that the reservoir is dominated by flow in natural fractures that connect the reservoir to the far-field. When the injection flow is doubled, the production flow rate stays approximately constant. Also, during...

the prediction of porosity is achieved by using available core and log data; however, the estimationof permeability is limited to the scare core data. hence, porosity and saturation data through theframework of flow units can be used to make an estimation of reservoir permeability. the purposeof this study is to predict the permeability of a carbonate gas reservoir by using physical-basedempiri...

Vacuum-assisted venous drainage (VAVD) is frequently used to increase venous return through smaller venous cannula and reduced venous line size. The purpose of this study is to determine the maximal flow rates achieved through various venous cannula with varying amounts of negative pressure applied during VAVD. The first test circuit consisted of 25 different venous cannulae connected to 3/8 in...

In this research, a 2D laterally averaged model of hydrodynamics and water quality, CE-QUAL-W2, was applied to simulate water quality parameters in the Ilam reservoir. The water quality of Ilam reservoir was obtained between mesotrophic and eutrophic based on the measured data including chlorophyll a, total phosphorus and subsurface oxygen saturation. The CE-QUAL-W2 model was calibrated and ver...
