The recovery factor of an oil reservoir is the proportion of the oil that can be economically recovered. One way to increase the recovery factor is to reduce the amount of oil left behind, or the residual oil saturation.

Here's why:

1. Reduce residual oil saturation: If the residual oil saturation is reduced, more oil can be extracted from the reservoir, increasing the recovery factor. This is often the aim of enhanced oil recovery (EOR) techniques.

2. Increase residual oil saturation: Increasing the residual oil saturation would mean leaving more oil behind in the reservoir, which would decrease the recovery factor, not increase it.

3. Decrease Porosity: Decreasing the porosity would reduce the amount of space available for oil storage in the reservoir, which would likely decrease the recovery factor.

4. Increase Porosity: While increasing the porosity would increase the potential storage space for oil in the reservoir, it doesn't necessarily mean that more oil can be recovered. The ability to recover oil depends more on the permeability of the reservoir and the residual oil saturation than on the porosity.

So, the correct answer is Reduce residual oil saturation.
