Episode notes
Deepwater Horizon Was A Top Tier Rig
- Deepwater Horizon was a highly valued, advanced rig leased to BP that tapped some of the deepest wells in the Gulf.
- Commissioned in 2001, Transocean paid over half a billion for the rig and it discovered numerous deep oil deposits before 2010.
Drilling Mud Is The First Line Of Defense
- Drilling requires circulating heavy 'mud' down the well to counter reservoir pressure and prevent uncontrolled flows called kicks.
- If reservoir oil overwhelms the mud and reaches the rig, a blowout can occur with oil and gas bursting onto the platform.
Corporate Schedule Pressure Compromised Safety
- Scheduling pressure and cost incentives pushed BP to hurry the Macondo well closure despite operational concerns and maintenance needs.
- The rig was a month over schedule, costing BP ~$1 million per day and several critical systems were overdue for service.
