b) The estimated quantity of oil and gas that can be commercially recovered under current economic conditions.
2. What are the two main categories of Proved Reserves?
a) Proven and Probable Reserves b) Development and Undeveloped Reserves c) Conventional and Unconventional Reserves d) Liquid and Gaseous Reserves
b) Development and Undeveloped Reserves
3. Which method for estimating Proved Reserves involves detailed analysis of geological data and well performance?
a) Probabilistic Methods b) Deterministic Methods c) Statistical Methods d) Predictive Methods
b) Deterministic Methods
4. Why are Proved Reserves important for investment decisions?
a) They help investors understand the potential profitability of an oil and gas company. b) They provide a measure of the company's environmental impact. c) They indicate the total amount of oil and gas that can be produced. d) They reveal the company's future exploration plans.
a) They help investors understand the potential profitability of an oil and gas company.
5. What is a significant challenge associated with Proved Reserves?
a) The lack of reliable data on well performance. b) The increasing cost of exploration and development. c) The dynamic nature of reserves due to factors like technological advancements and market conditions. d) The difficulty in accurately estimating the amount of oil and gas recovered.
c) The dynamic nature of reserves due to factors like technological advancements and market conditions.
Scenario: An oil and gas company has reported Proved Reserves of 100 million barrels of oil equivalent (boe) at the beginning of the year. During the year, the company discovered a new field with an estimated 20 million boe of Proved Reserves. However, due to a decline in oil prices, the company had to write down 5 million boe from its existing reserves.
Task:
1. **Proved Reserves at the end of the year:** - Initial Proved Reserves: 100 million boe - New discovery: +20 million boe - Write-down: -5 million boe - **Total Proved Reserves at year-end: 115 million boe**
2. **Impact on valuation:** - The increase in Proved Reserves due to the new discovery would generally increase the company's valuation. Investors would view this as a positive indicator of future production and revenue. - However, the write-down of 5 million boe due to the decline in oil prices would negatively impact the company's valuation. This reflects a decrease in the company's immediate earning potential. - The overall impact on valuation depends on the relative size of the new discovery and the write-down, as well as other factors like market conditions and investor sentiment.
