"Injectivity Testing" Testing Completed, BP Begins Pumping Mud Into Well
Began began pumping heavy drilling mud into its blown out Macondo well Monday afternoon.
NPR quoted Thad Allen, the incident commander, as saying it could take a day or more to fill the pipe with mud. Then cement will be poured on top of the mud.
The oil company began tests at 1:05 p.m. and two hours later BP was allowed to begin pumping the mud for what is called a "static kill."
Allen said the work was delayed from Monday night because some leaks were discovered. They were repaired.
Although it would be a major step forward, more work will be needed because the static kill might not reach into a portion of the well pipeline.
"The relief wells are the answer. This thing won't truly be sealed until the relief wells are done," said Allen.
Aug. 15 is the projected date for the completion of the first relief well.
No oil has leaked since a cap was installed 19 days ago.
