BK Lim cites NOVEMBER videos showing “oil seepages, gas columns, fissures and blowout craters” around Macondo wellhead (VIDEOS)


Original story here: A Letter to Congressmen on BP Mega Oil Spill in the Gulf, BK Lim, January 14, 2011.

The following ROV videos show the "oil seepages, gas columns, fissures and blowout craters in the seafloor around the Macondo wellhead" discussed by BK Lim in his January 14, 2011 letter.

Mr. Lim is a Geohazards Specialist with 30 years experience in the Oil and Gas Industry working for clients such as Shell, Petronas, ENI, and Pearl Oil.

Video #1, November 5, 2010: "In this footage you will see a tilting wellhead with rising clouds of methane saturated seawater, gas bubbles of methane and re-crystallized methane crystals floating close to the seabed in the vicinity of the Macondo wellhead. You can also see new fissures and a bulging seabed developing together with an already blown crater."

Video #2, November 10, 2010: "In this footage you can see the horizontal white guide rope for the surveying ROV disappearing into a dense, darkish cloud of oily fluid. The white specks falling slowly to the seabed are probably remnant pieces of the grout that had been carried to higher altitude by a rising column of gas at the active venting fissures. The re-crystallized methane is more feathery (transparent and lighter) and seems life-like with changing color due to refracted light."

Video #3, November 1, 2010: "A short video capturing the periodic expulsion of gas through one of the fissures on the seabed. Like geysers, the escaping gas needs to accumulate beneath the top sediment cover until the built-up pressure exceeds the combined water-column and overburden pressure just before each periodic expulsion."
