Tight oil reservoirs typically have an estimated ultimate recovery of less than 10% after hydraulic fracturing, where enhanced oil recovery (EOR) technique is needed. Comparing to the gas-EOR, the surfactant-EOR neither alters the current fracturing…
Increasing energy and environmental demands raise intensive interests on cleaner but challenging resource explorations, where unconventional tight reservoirs attract attentions due to its huge reserves but complex reservoir conditions. As…
