Instructions: Choose the best answer for each question.
1. What does Formation GLR (Gas-Liquid Ratio) represent?
a) The volume of oil produced per unit volume of gas.
Incorrect. Formation GLR represents the volume of gas produced per unit volume of liquid (typically oil).
b) The volume of gas produced per unit volume of liquid.
Correct. Formation GLR represents the volume of gas produced per unit volume of liquid (typically oil).
c) The ratio of gas to liquid in a reservoir.
Incorrect. While related to the gas and liquid content, Formation GLR specifically quantifies the volume of gas produced per unit volume of liquid.
d) The total volume of hydrocarbons produced.
Incorrect. Formation GLR focuses on the relationship between gas and liquid production, not the total volume.
2. Which of the following is NOT a factor influencing Formation GLR?
a) Reservoir pressure
Incorrect. Reservoir pressure significantly impacts Formation GLR.
b) Reservoir temperature
Incorrect. Reservoir temperature influences gas solubility, affecting Formation GLR.
c) Production rate
Incorrect. Production rate can lead to gas expansion, altering Formation GLR.
d) Wellhead pressure
Correct. Wellhead pressure is not a direct factor influencing Formation GLR. Formation GLR is determined by reservoir conditions.
3. How does a high Formation GLR impact production planning?
a) It requires fewer processing facilities for gas separation.
Incorrect. A high Formation GLR indicates more gas production, requiring specialized processing facilities.
b) It makes production more cost-effective.
Incorrect. High Formation GLRs typically lead to higher processing costs.
c) It requires specialized gas handling and transportation infrastructure.
Correct. High Formation GLRs require specialized equipment and strategies for efficient gas separation and transportation.
d) It makes it easier to estimate reserves.
Incorrect. While FGLR provides insights, it doesn't necessarily simplify reserve estimations.
4. Which of the following methods is NOT used to measure or analyze Formation GLR?
a) Well testing
Incorrect. Well testing is a crucial method for measuring FGLR.
b) Production data analysis
Incorrect. Continuous monitoring of production data provides valuable information about FGLR.
c) Seismic surveys
Correct. Seismic surveys primarily focus on reservoir structure and hydrocarbon presence, not direct FGLR measurement.
d) Laboratory analysis
Incorrect. Laboratory analysis of fluid samples can contribute to understanding FGLR.
5. How does understanding Formation GLR benefit oil and gas companies?
a) It helps determine the optimal well completion strategy.
Correct. FGLR data informs decisions about well completion methods and production strategies.
b) It helps identify potential environmental risks.
Incorrect. While FGLR is relevant to production, it doesn't directly address environmental risks.
c) It allows for accurate prediction of future oil prices.
Incorrect. FGLR primarily focuses on production aspects, not market price predictions.
d) It eliminates the need for reservoir simulations.
Incorrect. FGLR is a key input for reservoir simulations, enhancing their accuracy.
