Effect of Slugs Arrangement Injection During Chemical Flooding in Vuggy Rocks

Fifty percent of the world’s oil in place is in dolomite reservoirs. A significant part of this oil is in highly heterogeneous, fractured and vuggy rocks. A set of core flooding tests using the surfactant and polymer is utilized to check the oil recovery efficiency from vuggy rocks containing light oil, the same as an oil reservoir located in the south of Iran. Polymer injection prior to surfactant flooding is tested and verified through this laboratory investigation.
