Rapid Estimation of Water Flooding Performance and Optimization in EOR by Using Capacitance Resistive Model

Water Flooding Performance Evaluation Using Percolation Theory

Water flooding is a well-known secondary mechanism for improving oil recovery. Conventional approach to evaluate the performance of a water flooding process (e.g. breakthrough and post breakthrough behavior) is to establish a reliable geological reservoir model, upscale it, and then perform flow simulations. To evaluate the uncertainty in the breakthrough time or post breakthrough behavior, thi...

Optimized polymer enhanced foam flooding for ordinary heavy oil reservoir after cross-linked polymer flooding

A successful cross-linked polymer flooding has been implemented in JD reservoir, an ordinary heavy oil reservoir with high permeability zones. For all that, there are still significant volumes of continuous oil remaining in place, which can not be easily extracted due to stronger vertical heterogeneity. Considering selective plugging feature, polymer enhanced foam (PEF) flooding was taken as fo...

Comparison of optimized flooding techniques

Flooding is an often used technique to distribute messages in a mobile ad hoc networks(MANETs). Each node in the network retransmits the message, so long as it receives one. The problem of this mechanism is the huge redundancy of messages. Several mechanisms are proposed in order to limit or optimize the flooding in MANET. In this paper we will discuss two of them: multipoint relays(MPRs) and c...

Performance of Air Foam Flooding under Low Frequency Vibration

Foam injection is widely applied in amounts of fields to drilling, production, and formation protection. Sometimes, the application result is disappointing, which is caused by the failure of bubble generation in foam flooding. Therefore, it is necessary to seek ways for improving the performance of foam injection. An increased disturbance to the stratum, like the vibration caused by a seismic o...
