ROV Thomas Jefferson Finds Seeps Near Rigel Methane Field

Just click this link instead of reading my post and speculations to make up your own mind without my ramblings I’ve posted just for my own study:

…………………… Several seeps southwest of the BP blow-out were first reported on June 21, 2010 by scientists aboard the R/V Thomas Jefferson. The seepage “appears to be natural gas” (methane) according to the NOAA report  http://www.noaanews.noaa.gov/stories2010/20100620_jefferson.html

………………….Former Shell Oil executive and current Berkeley engineering professor Robert Bea is “troubled that we’re just now hearing about seeps three kilometers away, because a survey of the seabed conducted before BP drilled its well didn’t indicate anything like that,” according to the Times-Picayune http://www.nola.com/news/gulf-oil-spill/index.ssf/2010/07/gas_seeps_not_necessarily_a_pr.html

…………………………………………..July 23 JAG report image shows areas of seepage near the BP blow-out, with the majority appearing near the Rigel gas field…………………..More information on the Rigel gas field:  http://www.floridaoilspilllaw.com/breaking-feds-seepage-likely-from-the-rigel-well-a-highly-successful-unproduced-gas-field  and  http://www.floridaoilspilllaw.com/rigel-gas-field-flowing-bps-blownout    video of Coast Guard admitting seeps 3 kilometers from Mocando Oil Well site……………………………The Rigel exploration well, the Texaco OCS-G-18207 #1, was drilled in 1999 in Gulf of Mexico block MC 252 in 5200’ water depth. The well targeted a Miocene age, low-relief downthrown closure/stratigraphic trap that was supported by a strong amplitude response on the 3D seismic data. … The well encountered what was interpreted to be a 176’ thick gas-charged, low-permeability siltstone in the Rob E-age target. …The appraisal drilling by Dominion, the operator, with its partners, Mariner and Newfield, was highly successful. As a result, the Rigel field is currently being developed as a one-well subsea tieback, as part of a larger subsea system. The project is nearly complete Wednesday 16-Nov-05.  http://www.spegcs.org/en/cev/?864   …………………..

Now I am getting a bit alarmed!  I’m just a layperson trying to make connections to all the events, geology, and well sites, active as well as inactive, and the people involved.  My studies of these have lead me to understand that the area concerned is filled with salt diaper/ batholithic formations and asphaltic volcanoes of an active nature.  Now adding this information of the Rigel gas field near by the Macondo oil drill site I am amazed that anyone would undertake such a dangerous region, dangerous depth, and close proxcimity to a methane gas well of that magnitude.  I know very little, yet it sounds dangerous to me!   Again here’s this material and all these links are found here:

…………………………………………………………….Here is history of Two (2) linked (by alrea flowline) gas wells, Rigel and 17 Hands:…………………………Houston, TX … The MTS Houston Section will meet on May 25, 2006 to hear a presentation on the Rigel/17 Hands Development given by Dominion’s Project Manager, Lawrence L. Starlight. Rigel/17 Hands is a two-well, subsea, dry gas development in the Mississippi Canyon 252 area of the Gulf of Mexico, in water depths ranging from 3400 feet to 5800 feet. The two wells are tied back to the Chevron VK 900 host facility via the alrea flowline. All the equipment and controls were designed to be compatible with the existing Chevron system.  The distance from the host facility to the Rigel and 17 Hands wells is approximately 40 and 50 miles, respectively. Combined flow rates from the two dry gas wells is around 150 MMCFPD. Partners in the development are Dominion, the operator, Mariner, Murphy, Newfield and Hydro (formerly Spinnaker). The host facility and Gemini subsea manifold are owned and operated by Chevron……………………………….http://www.oilonline.com/News/NewsArticles/articleType/ArticleView/articleId/17354/MTS-Houston-presentation-May-25-to-feature-Dominions-Rigel17-Hands-Subsea-Development-in-the-GOM.aspx …………………………………………………….
More background:  Dominion Exploration and Production has made a deepwater discovery at its Rigel prospect, located at Mississippi Canyon Block 296 in the Gulf of Mexico. The discovery is located in about 5,200′ of water… drilled to a total depth of about 16,200′ and encountered 140′ of gross gas pay in the main Rob E objective…………………………Speculation about a possible impact on the Rigel well did occur at the Oil Drum. Once. About a month ago.  BP’s Deepwater Oil Spill – The Admiral on Casing and Connections, Oil Drum, June 21, 2010:  http://www.theoildrum.com/node/6637
COMMENT BY ‘LURKING’
Anybody happen to know if the Rigel or 17 Hands gas fields are in danger of being affected by fluids from the BP stovepipe?…The reason I ask is that over the last few days, I’ve seen what appear to be more gas in the plume… as if I can tell what it is when I see it. I’m referring to the globs of bluish white that you see in the plume.. not the milky dispersant from the nozzles. I have no idea what the pay depth for those two fields are, but if they are contributing to the flow… that would be bad.
RESPONSE BY ‘BIGNERD’  Funny, I was looking at that the other day.  I’ve got a map which shows what I think is the Macondo well over to the east side of the 252 block, whereas the Rigel field straddles the southern boundary.  The Seventeen Hands gas line and an oil export line from Na Kika both cross the block in the south and west.  So all other on block infrastructure looks to be about 3 km to the south and west of the Macondo well.
RESPONSE BY ‘LURKING’  The Rigel prospect has a measured depth of 16,200 feet. Macondo was drilled to 18,000 feet (and change). …[I]t seems to me that 3 to 7 miles is not that far in strata that is as close as 340 vertical feet apart and that varies from impermeable to highly porous.  [The Macondo well] had to drill past (through?) that level [of the Rigel well] with what is now a casing of dubious integrity.  *sigh….

Next in the article is a Bathymetry Map of the Macondo area and other visuals.  Main link:  http://www.floridaoilspilllaw.com/at-least-six-seeps-found-near-rigel-well-southwest-of-bp-oil-blow-out-photos
