Incorrect. This is a separate process called gas processing.
c) By increasing the pressure at the wellhead, leading to greater flow.
Correct! Increased pressure leads to more gas flowing through the pipeline.
d) By converting gas into liquid form.
Incorrect. This is a different process called liquefaction.
3. Which type of compressor is commonly used for high-volume, low-pressure gas applications?
a) Reciprocating Compressor
Incorrect. Reciprocating compressors are more suitable for smaller volumes and higher pressures.
b) Screw Compressor
Incorrect. Screw compressors are versatile but not typically the best choice for extremely high volumes.
c) Centrifugal Compressor
Correct! Centrifugal compressors excel in high-volume, low-pressure applications.
d) Rotary Compressor
Incorrect. While rotary compressors are used in some oil & gas applications, they are not the primary choice for high-volume, low-pressure gas.

5. What is a key benefit of using compressors in oil & gas operations?
a) Reduced environmental impact.
Incorrect. While energy efficiency improvements reduce impact, it's not the primary benefit.
b) Increased gas production.
Correct! Higher pressure leads to higher production rates.
c) Lower operating costs.
Incorrect. While optimized production can lead to savings, it's not the primary benefit.
d) Elimination of the need for pipelines.
Incorrect. Pipelines are still essential for transporting gas.
Scenario: A gas well is producing at a rate of 1 million cubic feet per day (MMcfd) at a pressure of 500 psi. To meet pipeline requirements, the pressure needs to be boosted to 1000 psi. You are tasked with selecting a compressor for this application.
Instructions:
**
**1. Suitable Compressor Type:** Based on the given conditions (1 MMcfd and a pressure increase from 500 psi to 1000 psi), a **centrifugal compressor** would be the most suitable choice.
**2. Reasoning:** * **High Volume:** Centrifugal compressors are designed for high-volume gas flows, making them ideal for this 1 MMcfd well. * **Moderate Pressure Increase:** The pressure increase requirement (from 500 to 1000 psi) falls within the operating range of centrifugal compressors.
**3. Factors to Consider:** * **Gas Properties:** Composition, density, and temperature influence compressor selection. * **Flow Rate:** The volume of gas to be compressed dictates the size and type of compressor needed. * **Pressure Requirements:** The desired discharge pressure dictates the compressor's capacity. * **Efficiency and Operating Costs:** Energy efficiency and maintenance costs are crucial factors. * **Environmental Impact:** Compressor emissions and energy consumption need to be considered.
