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...

The flow field is the fluid dynamic path in strongly heterogeneous reservoirs, and its evolution significantly affects distribution of remaining oil, showing a disordered highly dispersed mode caused by long-time water injection. By combining traditional flow-field evaluation with diagnostics, this paper proposes methodology to quantitatively characterize adjust real time during late stage wate...

Study on the interlayer has developed associated with in-depth exploration and development of oil fields, which is an indispensable part to characterize reservoir heterogeneity. This study relates to a comprehensive research method of interlayer in rhythmic layering in continental low permeability reservoirs. During the process of waterflooding development, distribution characteristics of inter...

Field trials have demonstrated that foamed gel is a very cost-effective technology for profile modification and water shut-off. However, the mechanisms of profile modification and flow behavior of foamed gel in non-homogeneous porous media are not yet well understood. In order to investigate these mechanisms and the interactions between foamed gel and oil in porous media, coreflooding and pore-...

The complex physics of multiphase flow in porous media are usually modeled at the field scale using Darcy-type formulations. The key descriptors of such models are the relative permeabilities to each of the flowing phases. It is well known that, whenever the fluid saturations undergo a cyclic process, relative permeabilities display hysteresis effects. In this paper, we investigate hysteresis i...

In this paper we introduce a new analytical approach for management of waterfloods in heterogeneous reservoirs. The main contribution is the development of a process and metric to evaluate the pair-wise injector-producer (IP) relationships, i.e., to quantify the impact of any injection well on the neighboring producing wells. The proposed metric is particularly designed to consider the non-line...

Detailed geological models typically contain many more cells than can be accommodated by reservoir simulation due to computer time and memory constraints. However, recovery predictions performed on a coarser upscaled mesh are inevitably less accurate than those performed on the initial fine mesh. Recent studies have shown how to use both coarse and fine mesh information during waterflooding sim...

Recovery efficiency is a key factor in decision-making oil and gas projects. Although structural setup well type considerably influence waterflood recovery, few studies have explored the performance of highly deviated wells during waterflooding complex shallow reservoirs. Here, we applied numerical simulations to investigate vertical, horizontal, multilateral, reservoirs using J1 Oilfield as ca...
