This article discusses development of the "Polymer flooding" module for distributed information system of oil fields development analysis. This module is designed to simulate displacement of oil using polymer injection method for 1532 Timur Imankulov et al. enhanced oil recovery and based on modern mathematical model that considers influence of salt and polymer concentrations on viscosity of in...

An amphiphilic silk-like protein polymer was efficiently produced in the yeast Pichia pastoris. The secreted product was fully intact and was purified by solubilization in formic acid and subsequent precipitation of denatured host proteins upon dilution with water. In aqueous alkaline solution, the negatively charged acidic polymer assumed extended helical (silk III-like) and unordered conforma...

A parallel reservoir simulator has been developed, which is designed for large-scale black oil simulations. It handles three phases, including water, oil and gas, and three components, including water, oil and gas. This simulator can calculate traditional reservoir models and naturally fractured models. Various well operations are supported, such as water flooding, gas flooding and polymer floo...

Modeling Chemical EOR Processes: Some Illustrations from Lab to Reservoir Scale — Chemical flooding, SP (Surfactant Polymer) or ASP (Alkali-Surfactant-Polymer), are of increasing interest due to the need to increase oil production. Design of chemical processes is very project specific and requires case by case studies including various steps among which reservoir data analysis, chemical formula...

Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...

China’s economy is in an important period of rapid development, the rise various industries to produce a greater demand for oil, oil exploitation industry has become focus whole society. The vast majority fields China have entered polymer flooding development stage, and reservoir been effectively improved. subsequent water can make further excavated, which key technology recent years. This pape...
