| Interpretation of geochemical researches of oil and formation water of one particular oil field (Republic of Kazakhstan) | |
| 46 oil samples were collected at the wellheads of different wells of a particular oil field and “oil fingerprinting” was performed by gas chromatographic analysis on LTM-MD-GC in order to understand the fluid connectivity of the reservoir within the field. This field located in the eastern edge of the Caspian Basin. According to the results of cluster analyzes, it was found that the studied samples of the north-eastern part of the oil field differ from those of the south-western part. Since the oil field has a massive reservoir height, all wells operate with minimum water-cut values, except for the production well. In this regard, the ionic composition of the water and the titration method were used to analyze the ionic composition of water, separated from the oil of producing well, two neighboring injection wells and block cluster pumping station of this field, to determine the ionic composition and identify differences and similarities of waters at the molecular level. According to the results of the analyzes, we came to the conclusion that all the studied formation water samples have common origin. The relatively high NaCl value in producing well water may be due to the high concentration of chloride in the oil. Keywords: oil fingerprinting, water fingerprinting, reservoir fluid connectivity, massive reservoir, Caspian Basin, Republic of Kazakhstan. |
