Degradation of chemicals at high temperature. Polymer  Need for Enhanced Oil Recovery 2 By: Alexey Andrianov, PhD Despite periods of uncertainty and fluctuating oil prices, world’s oil demand is growing, on average by 2% per year. On average 65% of oil in place (OIP) remain in reservoir after primary and secondary recovery. The range of remaining oil in oil fields can be from 40 to 95%. In this report, the global Chemical Enhanced Oil Recovery EOR market is valued at USD XX million in 2016 and is expected to reach USD XX million by the end of 2022, growing at a CAGR of XX% between 2016 and 2022.

altered to be non oil wetting. SEMAR (Solution by Chemical Modifier to Enhance Recovery) is a special chemical modified to accelerate recovery of oil fields. With a low concentration in a system, SeMAR has the ability to imbibe and alter the amount of energy on the surface or interfacial layers of the system.

In the steam zone the oil evaporates and in the hot water zone the oil expands. As a result, the oil expands, the viscosity drops and the permeability increases. To ensure success, the process has to be cyclical. This is the principal enhanced oil recovery program in use today.

Microbial enhanced oil recovery (MEOR) is motivated by the fact that numerous core scale experiments have shown an increased oil production due to microbial activity. In some cases the increased oil production has been extremely high while in some cases very low (see Bryant and Lockhart (2000)). 7 EORScreening)Criteria) Property CO2/ NGL/ WAG N2 Steam Drive SAGD Polymer SP/ASP ACP Low Tension Gas Oil API >22 >40 >8 >6 >12 >12 12-25 >20 1. EOR Methods Chandran Udumbasseri Technical Consultant Enhanced oil recovery (abbreviated EOR) is the implementation of various techniques for increasing the amount of crude oil that can be extracted from an oil field. Enhanced oil recovery is also called improved oil recovery or tertiary recovery 2. Chemical enhanced oil recovery is an advanced technology that addresses the mechanisms that produce oil. The standard way to view oil production is though the oil recovery equation shown below. Np =ED EV OOIP. Where: Np – Oil Recovery (Production) ED – Pore to Pore (Unit) Displacement Efficiency; EV – Volumetric Sweep Efficiency An Introduction to Enhanced Oil Recovery Techniques To better understand the differences and advantages of Sino Australia’s best practice Enhance d Oil Recovery (EOR) technologies and services, it can be useful to gain insight into the issues EOR seeks to address, how these issues have been addressed previously and how technology has Chemical Methods of Enhanced Oil Recovery • Surfactants to lower the interfacial tension between the oil and water or change the wettability of the rock • Water soluble polymers to increase the viscosity of the water • Surfactants to generate foams or emulsions • Polymer gels for blocking or diverting flow Chemical flood enhanced oil recovery 251 The typical flow curves of aqueous s olutions of partially hydrolysed polyacrylamide (PHPA) polymer at different conce ntrations are shown in Figure 8.
