05.13.10 Video of primary leak released By SFSDAdministrator BP officials released the first clear video of the primary leak at the Macondo Well site. In the video the flow is clearly evident - initially mixed somewhat with gas (most likely natural gas or possibly methane).

To help frame that for you, a firehose typically blows between 100-300 psi, with a bursting max of 1200 psi.
