in this paper, the role of molecular diffusion in mobilization of waterflood residual oil is examined. a moving mesh method is applied to solve the moving interface problem of residual oil blobs swelling by co2 diffusion through a blocking water phase. the results of this modeling are compared with experimental results of a 2d glass micromodel experiment. although, the solution method is applie...

Abstract The significance of the tracer testing technique is widely accepted in reservoir performance analysis hydrology as well hydrocarbon exploration and production. subsurface delineation for optimum production one most critical aspects petroleum system analysis. quality its prediction require extensive knowledge qualitative geology, depositional environment, facies heterogeneity engineerin...

The high water cut stage is an important of the injection development oilfields because there are still more oil reserves available for recovery in this stage. Most have experienced decades waterflooding and adjustment. Although reservoirs face problems seriously watered-out highly dispersed distribution remaining oil, they remain dominant waterflood development. This paper investigates current...

Abstract We predict waterflood displacement on a pore-by-pore basis using pore network modelling. The structure is captured by high-resolution image. then use an energy balance applied to images of the assign average contact angle, and modify local pore-scale angles in model about this mean match observed sequence. Two waterflooding experiments oil-wet rocks are analysed where sequence was imag...

This paper presents an overview of the factors involved in the selection of an active souring management solution for the Mars field, at which waterflood operations are due to commence in March 2004. It is well documented that the majority of similar seawater injection applications have experienced increased down-hole sulfate-reducing bacteria activity and the reservoir souring and H2S control ...
