"Gross production" is a term frequently used in the oil and gas industry, but its meaning can vary depending on the context. While it often refers to the total amount of fluids produced from a well or field, it can also represent the cumulative hydrocarbon production. This ambiguity can lead to confusion, so understanding the specific context is crucial.
Total Fluids Produced:
One common definition of gross production is the total amount of fluids produced from a well or field, including oil, gas, water, and other substances. This definition is often used in production reports, where the total gross production is broken down into its individual components.
For example, a production report might state that a well produced 100 barrels of oil, 500 thousand cubic feet of gas, and 200 barrels of water, resulting in a gross production of 800 barrels of fluid.
Cumulative Hydrocarbon Production:
In other contexts, "gross production" can refer to the cumulative amount of hydrocarbons (oil and gas) produced from a well or field. This definition is often used when discussing the total amount of resources extracted from a specific reservoir.
For instance, a company might report that the gross production from a particular field over its lifetime is 10 million barrels of oil equivalent (boe).
Understanding the Context:
The specific meaning of "gross production" depends on the context in which it is used. It is essential to carefully consider the context to avoid misinterpretations.
Key Considerations:
By understanding the context, you can accurately interpret the meaning of "gross production" in oil and gas reports and discussions.
Instructions: Choose the best answer for each question.
1. Which of the following is NOT typically included in the "total fluids produced" definition of gross production?
a) Oil b) Gas c) Water d) Sand
d) Sand
2. A production report states that a well produced 200 barrels of oil, 1000 thousand cubic feet of gas, and 50 barrels of water. What is the gross production in barrels of fluid?
a) 200 barrels b) 1000 barrels c) 1250 barrels d) 1300 barrels
c) 1250 barrels
3. "Gross production" can refer to the cumulative amount of hydrocarbons produced from a well or field. Which of the following units is commonly used for this definition?
a) Barrels of oil (bbl) b) Thousand cubic feet (Mcf) of gas c) Barrels of oil equivalent (boe) d) All of the above
d) All of the above
4. A company reports a "gross production" of 5 million barrels of oil equivalent (boe) from a specific field. This likely refers to:
a) The total amount of fluids produced from the field over a year. b) The total amount of oil produced from the field over its lifetime. c) The total amount of hydrocarbons (oil and gas) produced from the field over its lifetime. d) The total amount of oil and water produced from the field over a month.
c) The total amount of hydrocarbons (oil and gas) produced from the field over its lifetime.
5. Which of the following is NOT a key consideration when interpreting "gross production"?
a) The specific unit of measurement b) The scope of the production c) The company's overall production strategy d) The time period considered
c) The company's overall production strategy
Scenario:
You are reviewing a production report for a well. The report states the following:
Task:
1. **Gross production in barrels of fluid:** 150 barrels (oil) + 30 barrels (water) = **180 barrels of fluid** 2. **Gas production in boe:** 750 Mcf / 6,000 cubic feet per barrel = **125 boe** 3. **Total gross production in boe:** 150 boe (oil) + 125 boe (gas) = **275 boe**
