The Universal Journal of Petroleum Sciences covers activity and development in the field of innovative developments in all kinds of petroleum engineering, natural gas engineering and petroleum geology. Research in petroleum and gas on-shore and off-shore exploration, reservoir engineering, oil geophysics, petrophysics, petroleum geosciences, oil geochemistry, well testing analysis, oil and gas geology, petroleum economics, multi-phase flows of petroleum and gas, reservoir simulation, drilling methods and fluids, production engineering, reservoir simulation, environmental aspects of petroleum exploration, development of deposits, transport and storage of oil and gas, ecology and industrial safety, processing and petrochemistry is included. Contributions can be either analytical, experimental or numerical, covering all aspects of petroleum and gas sciences. So, the papers published should present innovative analytical and numerical methods and novel experimental methods, as well as non-linear methods and results, which should be far beyond the current "state of art".
