Romania is classified as a mature hydrocarbon province, but it is still the most important producer in the Central and South-Eastern European countries. Oil production in Romania has steadily declined overtime. Even if the earlier discovered fields have a high rate of depletion and the new discoveries do not compensate entirely the consumption, Romanian sedimentary basins have petroleum prospectivity. Thus, significant hydrocarbon potential remains in exploration, near-field opportunity and field rehabilitation. Significant oil exploration potential is still present in Romania. The general trend is near-field opportunity, going deeper and applying new technologies (3D seismic surveys, regional long-offset 2D lines for structurally complex and deep leads/prospects, AVO analysis of shallow targets and 2D/3D structural balancing) and new concepts (subtle traps). There is still an ongoing effort to redevelop mature oilfields in Romania; currently are used technologies as directional drilling, steam injection, water injection, polymer injection, and in-situ combustion. Romanian hydrocarbon basins have still areas with oil and gas resources entrapped in all kind of traps, especially subtle ones, and there is a great chance for new commercial discoveries. Potential new discoveries in Romania of conventional oil and gas fields are connected with foreland plays in little explored deep, subtle traps, deep overthrusted structures and deep offshore area. New oil and/or gas fields could be discovered at shallower depths in traps overlooked as a consequence of poor seismic results or insufficient research. The resource appraisal simulation for petroleum prospects analysis in Romania confirmed that the new prospects are primarily gas prone. The skills and the ability of exploration geoscientists will play an important role in any future success. The current Romanian proved reserves of 600 MMBOE oil and 100 BCM gas could be significant improved in the next years. In the paper we are underlined some future targets in the exploring for oil and gas in the main Romanian hydrocarbon basins.
