... Abstract Successful implementation of a recovery project in a fractured reservoir requires that the matrix fracture mass transfer is well understood. As a consequence, several processes involved in the mass transfer have been widely studied along time on account of its impact on the fractured...

... Abstract Numerical simulation of flow and mass transfer in fractured reservoir is challenging due to the complexity of the fracture networks. To handle the geological complexity, dual-porosity models are often used to approximate such reservoir settings. In dual-porosity models, it is assumed...

... a reaction. Lobanova and Indrupsky (2015 ) developed a non-equilibrium approach in a compositional simulator, based on a new flash calculation without changing the flow equations in the reservoir simulator. In their model, the component mass transfer parameter is defined as a function of the chemical...

... is completely displaced by the L 2 phase on the LCEP. The analysis indicates that mass transfer on multiphase transition occurs in the most efficient way for MCM development. Simple analytical conditions derived for MCM through three phases are applied to 1-D fine-scale simulations of CO 2 floods using four...

... Abstract The study of mass transfer between phases is a very important issue during drilling operations with organic based drilling fluids. The research in the area is necessary to understand the interaction between the formation fluid (oil and/or gas) and the synthetic drilling fluid filtrate...

... 25 - 27 . These three facts make the mass transfer become an extremely complicated moving boundary problem. On the other hand, the total gas mass transfer rate into the pendant oil drop is proportional to its surface area. For the crude oil-gas system, the diffusion process proceeds so slowly...

... that accounts for flow through liquid films, viscous flow in the bulk liquid phase of the clusters and mass transfer by diffusion in the gas phase is used. We study the effect of liquid films on phase distribution patterns and rates of recovery. We find that under strong capillarity conditions, the films span...

..., where the fracture and matrix systems are separated into different continua, each with its own set of properties. Matrix-fracture interaction governing mass transfer between matrices and fractures is modeled through a "Transfer Function" ( Barenblatt, 1960 ). This transfer function is the heart...

A heat transfer occurs between liquid and gas phases tending to attenuate the temperature variation of the gas phase. Equally, a mass transfer may...

We argue that models that do not account for these effects do not retain the qualitative features of the reactive dissolution process and hence cannot be predictive. The averaged model developed here accounts for pore level physics by coupling...

..., transportation of live oil with dissolved gas is a preferred option for waxy crude where gelling of the stock tank oil at reduced temperature is a problem. However, gas dissolution is not instantaneous because of finite mass transfer rate, a two-phase entrance region will exist, thus complicating the design...
