Anadarko Petroleum Corp. (NYSE:APC)

Total sales revenues exhibited a growth trajectory from 2012 through 2014, followed by a substantial contraction during the 2015 and 2016 fiscal years. The peak revenue was achieved in 2014, after which a significant downward trend occurred, indicating a sharp decline in the company's overall top-line performance.

Total Sales Revenues

Aggregate revenues increased from 13,307 million in 2012 to a peak of 16,375 million in 2014. A severe reversal followed in 2015, where revenues dropped to 9,486 million, further declining to 8,447 million by December 31, 2016.

Oil and Gas Exploration and Production

This segment showed consistent growth between 2012 and 2014, rising from 6,752 million to 8,603 million. However, a steep decline was observed thereafter, with revenues falling to 4,734 million in 2015 and 4,191 million in 2016, mirroring the broader trend of the total sales revenue.

Marketing Revenues

Marketing activities contributed heavily to the total revenue stream, peaking at 7,390 million in 2013. Similar to the exploration and production segment, this stream experienced a sharp contraction starting in 2015, falling to 4,025 million and reaching a low of 3,621 million by the end of 2016.

Midstream Segment Analysis

The midstream segment displayed a counter-cyclical trend compared to the other revenue streams. It grew consistently from 325 million in 2012 to a peak of 727 million in 2015, despite the decline in total sales. A slight contraction occurred in 2016, with revenues settling at 635 million.

The financial data indicates a high dependency on exploration, production, and marketing revenues, which were subject to significant volatility. The growth in the midstream segment provided a partial hedge, though it was insufficient to offset the substantial losses in the primary revenue-generating divisions between 2014 and 2016.
