| Summary: | It is known from the literature that up to 27 % of oil in oilfields can be produced using primary and hydration methods. The efficiency of production can be increased by employing more advanced methods, i.e. EOR. The Polish Oil and Gas Company iwork with Polish oilfields, where currently primary methods are applied, but the Polish experiences with EOR date back to the years 1932-1987. In view of high oil prices, reconsidering EOR as a production method is economically justifiable. Therefore, it is purposeful to implement new pilot technologies, aimed at implementing new technologies, understanding accompanying phenomena, and calibrating of simulation models, including economical models for an optimal control of the oilfield exploitation. World’s new exploitation methods worked out in the last few years and suggestions for their implementation in Polish conditions are presented in the paper
