Remotely Operated Vehicle footage of Macondo Well 252 collected Aug. 26, 2011
Following is a link to Remotely Operated Vehicle (ROV) video footage collected by BP of the Macondo well (MC 252 #1) and relief well (MC 252 #3) wellheads in response to a request from the US Coast Guard to investigate the possible source of a reported spill in the vicinity. These visual wellhead inspections, conducted on Aug. 25 and 26, 2011, confirmed that there is no release of oil from either well and that both wells are secure.
The ROV video inspection was conducted in the presence of representatives from the Gulf Coast Incident Management Team (GCIMT) (formerly MC252 Unified Command) located in New Orleans. GCIMT members watching the live video feed included representatives of the US Coast Guard, the Bureau of Ocean Energy Management, Regulation and Enforcement, the Department of Interior and representatives from the states of Louisiana, Mississippi and Florida.
The inspection was prompted by press reports that sheens of oil observed in the vicinity were from the Macondo well. The Macondo well was capped on July 15, 2010 and permanently killed by sealing the well and annulus with cement on Sept. 19, 2010. The well was later plugged and abandoned with the approval and oversight of the US government.
During the course of inspecting both wellheads, small, intermittent bubbles were observed emanating from cement ports at the base of the wellheads. These observations are consistent with testing and sampling performed last year that detected nitrogen bubbles, a residual byproduct of the nitrified foam used in setting the wells’ surface casing cement.
