Περίληψη
The need of more in quantity and more sufficient oil recovery from producing reservoir has led the oil industry to develop and apply methods that would serve this purpose. After the primary oil recovery, when the reservoir pressure is not enough, secondary recovery methods, such as waterflooding, are applied to maintain the pressure. At the end of these two phases a 30%- 40% of the total oil in place is produced. For the remained oil, EOR (Enhanced Oil Recovery) methods are used, such as ASP (Alkaline/Polymer/Surfactant) flooding, steam injection, microbial etc., to achieve a further recovery of 20%-30% of the oil. However, the application of an EOR methods needs evaluation before implementation, as every reservoir is different and has its own unique combination of physical characteristics. The most important parameter, which must be determined before EOR, in a waterflooded reservoir, is the residual oil saturation.
One way to measure the residual oil saturation is to perform well-logging, which may be difficult and expensive to apply due to well completions, (pumps). The use of tracer tests, either inter- or single- well tests has been proved more useful and more reliable, as the results are more representative of the whole reservoir.
Single-well tracer test are also applied after an EOR project, in order to measuring again the residual oil saturation and to evaluate the effectiveness of the EOR method.
This thesis will deal with single- well tracer tests. The procedure of the test and parameters that affect the reactions that take place during the test will be described. A short description of ASP flooding will also be presented. The effect of temperature and pH will be shown by sensitivity analysis and finally a history matching of real single-well tracer test data. The simulations are carried out using the UTCHEM simulator.
