The equilibrium and flow of polymer films and drops past a surface are characterized by the interface and surface tensions, viscosity, slip length and hydrodynamic boundary position. These parameters of the continuum description are extracted from molecular simulations of coarse-grained models. Hard, corrugated substrates are modelled by a Lennard-Jones solid while polymer brushes are studied a...

The North Burbank Unit, located in Osage County, was originally discovered in 1920. It has an extensive history of activity, including primary depletion, produced gas cycling, and water and polymer flooding to the point of very high water cut at current conditions. The current oil production rate in the North Burbank Unit is approximately 1,400 BOPD from 360 active wells at a water cut of 99.5%...

Polymer flooding is a tertiary oil recovery technology that very suitable for the characteristics of China’s reservoirs. However, due to fast flow rate polymer solution in near-well zone, shear effect perforation blasthole and compacted zone results serious loss viscosity. In this paper, used Dagang Oilfield studied by simulation experiment through shearing process perforating holes, influence ...
