Macondo’s Deepwater Horizon Disaster - Investigation, Capping and Relief Well Drilling

What We Did

Add Energy contributed throughout the entire kill operation and provided specialists contributing and assisting in three different teams:

1. Investigation Team
   The main task was to gather facts and to investigate the circumstances around the time of the incident in order to determine how, when and what went wrong.
2. Top Kill Team
   The primary kill operation was to install a Capping Stack on top of the existing subsea BOP, shut-in the well and bullhead hydrocarbons down the well.
3. Relief Well Team
   The second kill operation involved pumping cement into the lower part of the wellbore through intersection by a relief well. In parallel with other teams working relentlessly to kill the well, our experts focused on determining the flow path scenarios.

The OLGA-WELL-KILL software, tailor made by Add Energy proved to be a unique and significant tool used during investigation and kill planning.
