Abstract:The offshore oilfields in China have entered the mature stage with high water cut and recovery rate. Oilfield Q has an oil viscosity of only 5 cp, with a water cut of 95% and a recovery rate of more than 40%. It is challenging to maintain sustainable oil production with only waterflooding. The field production is close to the economic limit. Therefore, finding an effective and economical EOR technique is crucial to mature oilfield development.
In this paper, we proposed a new EOR method, called … Show more
