Recovery factor of oil

25 Sep 2019 Oil recovery factor (RF) is the most significant parameter for all exploration and development (E&P) companies mainly during the early reservoir  15 Mar 2017 In the case of unconventional oil reservoirs, the average recovery factor is between only 5% and 10% 2, meaning there is enormous potential for 

Globally, the overall recovery factors for combined primary and secondary recovery range between 35 and 45%. Increasing the recovery factor of maturing waterflooding projects by 10 to 30% could contribute significantly to the much-needed energy supply. Multiply OOIP original oil in place or OGIP original gas in place by the recovery factor for the expected drive. Narrow the recovery factor range by predicting the thickness of the reservoir by port type. Port type affects recovery rate. For example, in a reservoir with strong water drive and macroporosity, recovery will be up to 60%, mesoporosity recovery will be up to 20%, and microporosity recovery will be 0%. Recovery factor (RF) is the overall proportion of oil expected to be extracted from the UKCS. Over time, RF efficiency has increased; but with field complexity also increasing, the result is that overall RF has changed very little. where (i) RF is the recovery factor which is defined as the volume of oil recovered over the volume of oil initially in place (OIIP), both measured at surface conditions. (ii) E PS is the microscopic displacement efficiency. This describes the fraction of oil displaced from the pores by the injected water, in those pores which are contacted by the water. The typical recovery factor from water-flood operations is about 30%, depending on the properties of the oil and the characteristics of the reservoir rock. On average, the recovery factor after primary and secondary oil recovery operations is between 35 and 45%. Calculate the oil recovery factor where the estimate of recoverable oil is 20 liters and the estimate of in place oil is 5 liters. Solution: Oil Recovery Factor = 20 / 5 Petroleum calculator solving for oil recovery factor given estimate of recoverable oil and estimate of in place oil

19 Jun 2015 Primary recovery is also sometimes referred to as pressure depletion because Gravitational forces can be a major factor in oil recovery if the

This paper provides a comprehensive overview of the nature, status and prospects for EOR technologies. It explains why the average oil recovery factor worldwide is only between 20% and 40%, describes the factors that contribute to these low recoveries and indicates which of those factors EOR techniques can affect.

11 Aug 2014 Oil recovery factor can be enhanced up to 15.1 percents by gas injection in a shale reservoir which is hydraulically fractured, are specified  EORtechniques which can significantly increase the recovery factor from reservoirs through injection of some fluids in the reservoir to sweep the remaining oil.
