... al, 1989 ). However, in some cases, for example, for light oil, when modeling the effects of gas injection, for gas condensate fields, the use of black-oil models gives unsatisfactory results. Field development simulation, accompanied by such processes, requires the use of compositional models...

We use direct X-Ray technique to assess the spatial and temporal dynamics of in-situ saturations. Dual X-Ray energies are employed to assess the SS...

... water into the underlaying aquifer and up laying gas gap are large. Immiscible gas injection into the gas cap can support the pressure but massively increases the gas cut. In addition, displacement efficiency by gas flooding is poor. Simulation results of the surfactant flooding case shows better...

... Abstract Defining in-fill drilling locations seems a simple task in natural depletion reservoirs while in special fields like those under miscible gas injection operation is challenging. The aim of this paper is to scrutinize the production and injection of existing wells and derive some extra...

Abstract Equation-of-state (EOS) fluid characterization is used to model the behavior of hydrocarbon reservoirs when variation in the fluid composition has a significant influence on the recovery of hydrocarbons. Examples are miscible gas-injection processes, where mass transfer between...
