BP Deepwater Horizon Macondo Blowout: Gulf of Mexico
This paper examines the BP Macondo well blowout disaster in the Gulf of Mexico, beginning with an overview of the drilling operation's background, water depth, rig type, and reservoir characteristics. It identifies the key partners, shareholders, suppliers, and contractors involved — including BP, Transocean, Halliburton, and Cameron International — and traces a detailed chronological timeline of events from the initial exploration plan in 2009 through the explosion on April 20, 2010, and the 83-day series of failed containment efforts that followed. The paper concludes that BP was aware of critical equipment failures and operational risks but failed to adequately address them, resulting in the largest offshore oil spill in history.

What makes this paper effective
- The chronological timeline section is particularly strong, organizing a complex chain of technical and regulatory failures into a clear, event-by-event sequence that makes causation easy to follow.
- The numbered list of 10 containment attempts efficiently conveys the scope of BP's response efforts while making clear that most approaches failed, reinforcing the paper's central argument about organizational risk-taking.
- The identification of specific contractors, their roles, and the materials they used (e.g., nitrogen-foamed cement) grounds the analysis in concrete technical detail rather than vague generalization.
Key academic technique demonstrated
This paper demonstrates the use of a structured case study format — organizing background, stakeholders, chronology, and outcome into discrete sections — to build toward an evidence-based conclusion. Rather than stating the conclusion first, the writer allows the accumulated timeline evidence to support the final judgment that BP knowingly accepted unacceptable operational risk.
Structure breakdown
The paper opens with a brief operational overview establishing setting and scale, then moves through two preparatory sections identifying ownership and contractors. The core of the paper is the detailed event timeline, which transitions directly into the numbered list of containment attempts drawn from the Deepwater Horizon Study Group report. A concise conclusion synthesizes the evidence into a clear accountability claim. This structure suits case study writing at the undergraduate level.
Overview of the Macondo Well Operation
On April 22, 2010, an explosion ripped through the Deepwater Horizon drilling rig at the Macondo Exploration Well, located in Mississippi Canyon Block 252, approximately 41 miles off the coast of Louisiana. A fire burned for about 36 hours before a second blast sank the rig. The well's blowout preventer failed to activate, resulting in the largest oil leak in the history of offshore drilling (Gulf, Oil, and Gas, 2011).
The Macondo Exploration Well/Canyon 252 Block is located in the U.S. sector of the Gulf of Mexico. The water depth at the site is approximately 5,000 feet, and the well drilling depth reached approximately 18,000 feet (5,500 m) below sea level. Prior to the disaster, plans indicated that the well would be "plugged and suspended for subsequent completion as a subsea producer" (Gulf, Oil, and Gas, 2011).
Partners, Shareholders, and Key Contractors
The Macondo well operation involved three principal ownership partners. BP Plc held a 65% share as the operator of Canyon 252 Block. Anadarko Petroleum Corporation held a 25% share, and Mitsui Oil Exploration Co., Ltd. held the remaining 10% (Gulf, Oil, and Gas, 2011).
Several major suppliers, contractors, and service providers were involved in the operation:
Halliburton Co. performed the cementing work on the Macondo Exploration Well. A special nitrogen-foamed cement was used, which is more difficult to handle than standard cement. A cement bond log is used to document and evaluate the integrity of cement work performed on an oil well.
Plant Performance Services (P2S), a wholly owned subsidiary of Fluor Corporation, was selected by BP to execute two contracts supporting Gulf Coast clean-up efforts.
Transocean was the provider and operator of the Deepwater Horizon drilling rig — a floating semi-submersible drilling unit, ultra-deepwater, dynamically positioned, and column-stabilized. The rig cost $560 million and was built by Hyundai Heavy Industries.
BP Plc served as the operator of Canyon 252 Block.
Cameron International manufactured and supplied the blowout preventer (BOP) for the Macondo Exploration Well on Canyon 252 Block (Gulf, Oil, and Gas, 2011).
