Abstract

Many wells have been drilled in Albania to search oil traps in the carbonate reservoirs of the Ionian area. One of them is the Nokova-1 well, drilled in the overflow front of the Berati anticline belt. Geographically it is in Erindi region, southern Albania. Nokova-1 well has passed flysch deposits of Oligocene (Pg3) and carbonate deposits of Eocene - Paleocene (Pg1-Pg2). To conclude in the results presented at this paper, various geological and geochemical studies have been studied. During the drilling and testing processes, signs of oil and hydrocarbon gas have appeared, which contribute to the oil-bearing perspective of the region. Limited quantities of crude oil were obtained during the testing process. Samples taken from this oil were determined density, from which API was calculated. Also hydrocarbon composition was performed. According to samples analysis, are determined parameters of density (0.923 gr/cm3), API (21.8) and hydrocarbon composition as follows: saturate (49.20 %), aromatics (27.9%), saturate + aromatics (77.10 %), NSO-comp (14.86%), asphalt (7.95%), saturate/aromatics (1.763441%) and NSO-comp + asphalt (22.81%). The results of the hydrocarbon composition were correlated with those of the oil traps (carbonate reservoirs) in Albania. From this correlation we have concluded that the crude oil taken from the Nokova-1 well is light oil, it is not biodegradable. Nokova-1 well oil correlates with oil of oil traps in Amonica, Cakrani, Mollaj, which have been interpreted as oil traps of younger geological age. In conclusion, it can be said that the oil samples taken from the Nokova-1 well are results from the contribution of an oil trap that can be located at depth, or the result of new phases of hydrocarbon migration.
