A Comprehensive Review of the Oil Flow Mechanism and Numerical Simulations in Shale Oil Reservoirs

A Study on the Mechanism of Urea-assisted Steam Flooding in Heavy Oil Reservoirs

The Biqian-10 block, located in Henan Oilfield of Sinopic, contains many thin and interbedded reservoirs, which have been operated by cyclic steam stimulation for 20 years or more. Therefore, it is a challenge to implement the conventional steam flooding. In order to improve the recovery of steam flooding, urea was used to assist steam flooding. Urea can decompose into CO2 and NH3, which are be...

Effect of Fractional Flow Curves on the Heavy Oil and Light Oil Recoveries in Petroleum Reservoirs

A multi-core numerical framework for characterizing flow in oil reservoirs

This paper presents a numerical framework that enables scalable, parallel execution of engineering simulations on multi-core, shared memory architectures. Distribution of the simulations is done by selective hash-tabling of the model domain which spatially decomposes it into a number of orthogonal computational tasks. These tasks, the size of which is critical to optimal cache blocking and cons...

Model-based Control of Multiphase Flow in Subsurface Oil Reservoirs

An emerging method to increase the recovery of oil from subsurface reservoirs is the application of measurement and control techniques to better control the multiphase flow in the reservoir over the entire production period. In particular the use of sensors and remotely controllable valves in wells and at surface, in combination with large-scale reservoir flow models is promising. Various eleme...
