You have a laboratory analysis of a reservoir sample from an oil well producing 41.5°API stock tank oil at 941 scf/STB. The sample was obtained from the reservoir at 184°F and 3463 psig. The results are given below:

A. Determine the bubble-point pressure of the reservoir fluid.

B. Calculate the formation volume factor (FVF) at reservoir conditions.

C. Find the gas-oil ratio (GOR) at standard conditions (14.7 psia and 60°F).

D. Estimate the total volume of gas produced from the reservoir sample.

Final answer:

The student's questions pertain to finding certain properties of reservoir fluid, like bubble-point pressure, formation volume factor, and gas-oil ratio. To accurately answer, lab analysis data would be required, or the student would need to use PVT software or standard petroleum engineering correlations.

Step-by-step explanation:

The student is interested in learning about various properties of a reservoir fluid and how it behaves under specific conditions like temperature, pressure, and flow. Specifically, the questions focus on concepts such as the bubble-point pressure, the formation volume factor (FVF), the gas-oil ratio (GOR) at standard conditions, and estimating the total volume of gas produced from a reservoir sample. These are important for understanding the extraction and production behavior of oil reservoirs. Unfortunately, the specific laboratory analysis data required to perform the calculations is not provided, hence it is impossible to calculate the precise values requested. However, the student might be advised to use tools such as PVT (Pressure-Volume-Temperature) software or consult standard correlations and equations available in petroleum engineering literature to find these properties based on the reservoir sample characteristics provided.
