The paper presents the results of the study of the structure and depositional environments formation in the lower Miocene reservoirs in the Central area of Dragon field (Cuu Long basin, Vietnam offshore) based on litho-facial, electro-facial, seismic-facial analyses, and biostratigraphy data and the deposits thickness analysis. The geological model refining had been done through the core analysis, seismic interpretation, wireline logs integration and via defi-nition of the depositional environments. The results received permit to predict the depositional environments distribu-tion in the areas that were not identified by drilling, to make more exact the area oil reserves evaluation, to enhance the oil recovery.
