## Text Document: Financial Analysis and Oil Price Calculation
### Overview
The image contains a textual passage from a financial report discussing the management of operations and financial conditions across segments. It includes benchmark prices for crude oil and natural gas across three years (2011–2013) and a question about the percentage increase in WTI crude oil prices from 2011 to 2013. A "Gold Program" calculation and a "ZS-STD" response are provided.
### Components/Axes
- **Textual Data**:
- **Passage**: Describes financial analysis of segments, organized by geographic location and nature.
- **Benchmarks**:
- WTI crude oil prices (Dollars per bbl):
- 2011: $95.11
- 2012: $94.15
- 2013: $98.05
- Brent crude oil prices (Dollars per bbl):
- 2011: $111.26
- 2012: $111.65
- 2013: $108.64
- Henry Hub natural gas prices (Dollars per mmbtu):
- 2011: $4.04
- 2012: $2.79
- 2013: $3.65
- **Question**: "By what percentage did the average price of WTI crude oil increase from 2011 to 2013?"
- **Gold Program**:
- Calculation: `subtract(98.05, 95.11), divide(#, 95.11)`
- Result: 0.03091 (3.091%)
- **ZS-STD Response**: 3.9%
### Detailed Analysis
- **Price Trends**:
- WTI crude oil prices fluctuated between $94.15 (2012) and $98.05 (2013), with a net increase from 2011 ($95.11) to 2013.
- Brent crude oil prices decreased slightly from 2011 ($111.26) to 2013 ($108.64).
- Henry Hub natural gas prices dropped significantly from 2011 ($4.04) to 2012 ($2.79) but rebounded in 2013 ($3.65).
### Key Observations
1. The Gold Program calculates a **3.091% increase** in WTI crude oil prices from 2011 to 2013.
2. The ZS-STD response reports **3.9%**, which conflicts with the Gold Program’s result.
3. Discrepancy may arise from rounding differences, alternative calculation methods, or data interpretation.
### Interpretation
- The Gold Program’s calculation aligns with standard percentage change formulas:
$$
\text{Percentage Increase} = \frac{\text{Final Value} - \text{Initial Value}}{\text{Initial Value}} \times 100 = \frac{98.05 - 95.11}{95.11} \times 100 \approx 3.09\%
$$
- The ZS-STD response (3.9%) suggests either:
- A miscalculation or typo.
- Use of a different baseline (e.g., average prices across all years instead of 2011).
- Potential inclusion of additional data points not explicitly stated in the passage.
- The passage does not clarify whether "average price" refers to annual averages or a specific metric (e.g., monthly averages). This ambiguity could explain the discrepancy.
### Conclusion
The textual data provides clear benchmarks for crude oil and natural gas prices. The percentage increase in WTI crude oil from 2011 to 2013 is **3.09%** based on the Gold Program’s calculation. The ZS-STD response of 3.9% requires further validation to resolve inconsistencies.
