Setting out the existing ideas about the rate and duration processes of formation of oil and gas deposits. They are divided into three groups. The actual data are systematizing pointing to the modern processes of formation of oil and gas deposit. Noted the practical consequence of the establishment of such facts connected with bonus deposit development process optimization. The great duration of the formation of oil and gas deposits is explained the long duration of the existence of deposits at a constant or periodic recharge of hydrocarbons. The concept of "deposit" has various definitions in the literature. In according to the basic characteristics deposit is a single accumulation of oil and (or) gas trapped. It is the open and fluid systems that may be in the NGK in the three states of equilibrium, in the state of formation and destruction in the state. Deposits may have more than one source of hydrocarbons and be associated with different foci of hydrocarbon generation. Formation of deposits ar the complex, multifactorial, cyclic and pulsating process. It requires the careful study. Most oil and gas deposits are formed or reformed to varying degrees in recent times due to the activation of tectonic processes, processes of petroleum formation, migration and structural adjustment plan of young and old platforms May say also about the moving areas of the Alpine age and their peripherals (foredeeps). At late stages of multiscale oil and gas deposits in different geodynamic conditions observed stabilization of production at a certain level, which may persist indefinitely.
