... Gas oil Gravity Drainage (GOGD) is a highly efficient recovery mechanism in heavily fractured carbonate reservoirs, where gas is injected on the crest and water is produced from the aquifer to allow offtake of oil from the fracture network by horizontal wells. As the gas is injected on the crest...

... to demonstrate that our MRDP-DFM approach yields more realistic forecasts of oil recovery due to gravity drainage and imbibition in fractured reservoirs because it allows us to represent the multi-scale heterogeneities inherent to NFRs more realistically. It hence predicts recovery processes more accurately...

... to match the previously performed gas-oil gravity drainage (GOGD) experiments. We then generate a three-component synthetic oil to perform compositional simulations of gas injection at different enrichment conditions; immiscible, near-miscible and first-contact miscible. We show that ultimate recovery...

... towards producers. In such reservoirs one has to rely on natural mechanisms like capillary imbibition or gravity to recover oil from the matrix reservoir rock. In Middle-East fractured carbonates, the matrix rock is commonly oil-wet or mixed wet and only gravity drainage remains a feasible process...
