What symbol is used to represent solution gas-oil ratio?

• A. Rs
• B. Gas-Oil Ratio
• C. GOR
• D. Solution gas ratio

Answer: (A)

In this context, the amount of gas dissolved in crude oil at reservoir conditions per unit of oil is called the solution gas-oil ratio. The standard symbol for that quantity is Rs. This notation shows up in PVT data and reservoir simulations to describe how much gas remains in solution with the oil before any gas comes out of solution as pressure changes. It’s different from the gas-oil ratio (GOR), which typically refers to the amount of produced gas relative to produced oil at surface conditions. The terms “Gas-Oil Ratio” or “Solution gas ratio” aren’t the conventional symbol for this reservoir-measured quantity, so Rs is the best choice.
