... Abstract This paper presents an extensive analysis solvent injection at elevated temperatures to recover heavy- oil/bitumen from fractured carbonates. Three different solvents (propane, heptane and distillate oil - naphtha) were injected at different temperatures representing a wide range...

... with a low permeability. The physical model is packed and then saturated with a heavy oil sample at the connate water saturation. Pure propane and a mixture of n -butane and methane are used as respective solvents to extract two different heavy oil samples. The waterflooding effect is examined by performing...

... using a commercial numeric simulator. The injection of either propane or butane into sand packs or consolidated sandstones at elevated temperatures was simulated. A pressure-temperature sensitivity analysis was carried out for different core sizes to understand the dynamics of the gravity drainage...
