Oil Reservoir Recovery

Introduction

Oil Reservoir recovery tends to be very important when it comes to the oil production however not only oil production is deeply associated with it. Most importantly, it is the sustainability of the oil wells, which tends to be directly affected by the Oil Reservoir Recovery. In the pretext that the oil reserves are, depleting by each passing day thus the need to improve the oil reservoir recovery tends to become more significant. Oil Recovery Methods tends to be of honest concern not only to the companies involved in it but also for the world. Thus, in the context of this paper we intend to shed light on the Oil Recovery Methods, which tends to be chemical in nature. This is done in order to review the challenges posted by the chemical methods in order to improve the oil reservoir recovery. This is done in order to develop a comprehensive knowledge of the subject.

Hypothesis

The help of Chemical Additives can improve oil Recovery Methods so that it can be used to serve world.

Discussion

This section of the paper tends to reflect on the chemical methods, which can be of help to improve the oil reservoir recovery methods. Thus, the proposed methods of improvement are as follows:

Injection of polymers and polymeric micelle.

Surfactant injection processes.

Injection of alkaline solutions or alkaline additives combined with mixtures of alkali or alkali-surfactant-surfactant-polymer (ASP).

Because each site is unique in regard to the properties of crude oils and the porous medium, you must design systems characteristic chemical for each application. The chemical reagents used their concentrations in the injection process and their size will depend on the properties of fluids and porous media training, as well as for economic considerations. However, we can mention some basic criteria for selection for the development of projects of this type:

Then there will be a description of the main aspects of each method:

Polymer Injection

The basic principle is this method is the water may become more viscous after the addition of a water-soluble polymer, which leads to an improvement in the mobility ratio oil / water and thus can improve the efficiency of sweep and thus a higher rate of recovery (Nissen & Knapp, p.4). Among the polymers used for this method are the polysaccharides (or biopolymers) and polyacrylamide (PAA) and its derivatives. At low salinities the AAP have a higher mobility ratio by increasing the viscosity of water and ...
