Initial Action Plan
After the Site Survey was completed, a site assessment meeting was held with the operator's response team. The team concluded the only short term solution was to attempt a dynamic kill down the drillpipe. The Source Control Team was divided into four primary task forces to plan and execute the drillpipe kill attempt. Two additional task forces were established, one to start planning a relief well kill option and the other to deal with oil containment and removal via lagoons and pumping stations.Task force (1) | Coordinated by blowout firefighter team. Responsible for: clearing equipment off the location; install two 7" diverter lines attempting to reduce the flow rate through the crater; rig-up a pump-in tree on the drillpipe and perforate the drillstring at 2880 m just above the drill collars. |
Task force (2) | Coordinated by John Wright. Responsible for diagnostics which included evaluating the blowout flow potential, kill hydraulic plan, possible use of invert gunk as a kill fluid and potential for success based on the current equipment limitations and unknown flow parameters. |
Task force (3) | Coordinated by operator. Responsible for for the rig-up a mud mixing plant using active rig tanks and storage tanks; dig and fill three water pits of 15,000 bbls each, rig-up a mud transfer system and fabricate a low pressure manifold. |
Task force (4) | Coordinated by operator and pumping contractor. Responsible for the rig-up of high pressure pumping equipment and connection of three 5" lines (200 m long) from the pump plant to the wellhead. As no stimulation work was currently done in the region only cement trucks were available. The total rated HHP in the whole country was 5275 4000 effective @ 75% efficiency from four different contractors. All were mobilized. |
