What is the name of the well on which the Deepwater Horizon exploded and sank in April 2010?

• A. Deepwater One
• B. BP-252
• C. Macondo-1
• D. MC252

Answer: (D)

The key idea is that official well designations use a block-based identifier rather than an informal name. The Deepwater Horizon was drilling the Macondo Prospect, and in formal records the well is identified as MC252—the “MC” stands for Mississippi Canyon and “252” is the lease block number. While Macondo-1 is a commonly used name, MC252 is the standard designation used in investigations, maps, and regulatory filings. This is why MC252 is the correct reference for the well involved in the Deepwater Horizon incident.
