“…With the continuous consumption of conventional reservoir resources, the exploitation of unconventional oil, including heavy oil, has become the key to satisfying human demand for hydrocarbon fuels. According to statistical estimates, the total amount of recoverable heavy oil is almost equal to the remaining reserves of conventional oil in the world. , Presently, the available production methods are mainly based on thermal methods, such as steam-assisted gravity drainage (SAGD), , cyclic steam stimulation (CSS), , and steam flooding. , However, the large heat loss in the upper and lower rock formations of thin oil reservoirs and the reduction of steam quality in deep oil reservoirs cause the thermal methods to be less effective in improving the recovery rate and lowers economic efficiency. , In recent years, the cyclic solvent injection (CSI) process, also known as Huff-n-Puff, has attracted widespread attention owing to its excellent applicability in thin and deep reservoirs.…”

“…Permeability and porosity decrease as overburden pressure increases . The influence of stress on permeability has also been studied through stress experiments by some researchers. Steam temperature is an important factor affecting the recovery of oil during SAGD and an increase in temperature will change the relative permeability of a heavy oil reservoir. Oil sand samples are relatively loose and it is difficult to conduct displacement experiments without treatment. Therefore, many researchers use a sandpack displacement setup and a steam generator to study the changes of permeability during a steam injection process.…”
