A multiphase flow simulator will be used to obtain the specific flow characteristics to evaluate EV and ICDA for the above mentioned pipeline system. Internal corrosion...

.... A comparison of simulated flow performance showed that well locations selected using PPM technique exhibied consistently better performance and minimum variance. STOIIP and PPM techniques resulted in two totally different templates for the selection of well locations. PPM technique was coherent...

... Abstract The common approach of using refined grids and small time steps usually does not provide accurate and efficient numerical models to simulate horizontal-well pressure-transient tests. In most cases, this approach requires impracticably long computational times or creates artifacts...

Therefore, it is very important to consider the requirements of fracturing treatments when programming the exploitation project for one new oil field or the future adjustable project for the old field. Reservoir numerical simulation with hydraulic fractures...

... Abstract This paper addresses the simulation of nitrogen injection in naturally fractured reservoirs through different scenarios by using a conceptual model with isotropic and anisotropic matrix blocks. Since, in practice, nitrogen is injected under surface conditions, there is some concern...

... more economic than miscible ones. An approximate quasi-steady state reservoir simulator was developed and used to identify this superior mode of gas and water injection. Transient simulation could not be used for this purpose because of the numerical dispersion (truncation error) inherent...

... Abstract Three porosity types, matrix, vugs and fractures, are usually present in naturally fractured, vuggy carbonate reservoirs. The vugs are generally considered connected either to the matrix or to the fractures in numerical simulation. One of the challenges of modeling these reservoirs...
