This paper presents two case histories providing insight into source control operations at shallow water depths. The first case history discusses a capping procedure at the seabed in a water depth of 80 ft. Debris on the seafloor was cleared and a new platform was installed, incorporating the remaining legs of the damaged previous jacket up. Once the well was successfully capped and diverted, the drillstring was snubbed into the flowing well, which was then killed by means of a dynamic kill operation. The second case history discusses capping a burning high pressure gas well on a platform. Debris was cleared and removed from the platform, and eventually the well was capped and flowed to a pipeline. This work highlights how source control options should be considered and evaluated as part of emergency response plans for jackup rigs and platforms. Proper planning, organization, and task management are fundamental to a safe and successful operation. |
