as observed in some oil and gas countries, upstream service contracts, for instance buy-back contract in iran, would provide an appropriate environment for the development of oil and gas fields. however, certain cases, such as common structures and reservoirs, deep sea oil fields or second and third generations of an oil field may require more attractive contractual mechanisms in the eyes of io...

Future exploitation scheme of an oil reservoir in each cycle within its production life depends on the profitability of the current extraction scenario compared with predicted recoveries that acquire with applying other available methods. In fractured reservoirs appropriate time to pass from the gas injection process into chemical enhanced oil recovery (EOR) firmly depends on the oil extraction...

supply security of energy is one of the main challenges of industrialized countries in recent decades. also, it has been noted that in recent years other countries like new emergence asian countries and latin american countries, have understood the role and importance of energy. however, oil and gas have more importance for numerous reasons such as convenience availability, high thermal value a...

The oil expulsion efficiency and retention of shale affect the enrichment preservation oil. Two series semi-closed hydrous pyrolysis experiments were performed under in situ geological conditions on a Paleogene sample as comparable analog to evaluate generation potential Funing Formation Subei Basin. results show that 1) oil-generation capacity evolution different lithological combination sourc...

nowadays one of the most important energy sources is natural gas. by depletion of oil reservoirs in the world, natural gasâ will emerge as the future energy source for human life. one of the major concerns of gas suppliers is being able to supply this source of energy the entire year. this concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...
