Interpretation, Analysis and Discussion

Chapter
Part of the Springer Theses book series (Springer Theses)

Abstract

Apart from the basic routine core analysis, 20 cyclic core-flooding experiments and 11 NMR measurements were conducted on a total of 13 sandstone core samples during the experimental work carried out throughout this research. In addition, two chemical composition analyses were also done on the brine samples taken during the flooding tests. The results obtained through running the above-mentioned experiments were presented in details in the previous chapter. This chapter, however, is dedicated to the interpretation, analyses and discussion of those results, to find out how they help achieving the research objectives outlined earlier.
