Relief well could penetrate Macondo in 7-10 days

HOUSTON, July 8 -- The relief well being drilled by BP PLC to stop the flow of oil and gas from the Macondo well could penetrate the runaway well in 7-10 days, although the government is standing by an anticipated completion date of mid-August, National Incident Commander and retired US Coast Guard Adm. Thad Allen said on July 8.

The first of two relief wells was at a measured depth of 17,780 ft, Allen said. He did not have a measurement for the intersection depth immediately available. Previously, well operator BP has said Macondo was drilled to about 18,000 TVD.

“When they go to penetrate it, they’ll go through a series of spaces,” Allen said. There are multiple strings of casing and an annulus, a space, between each of them. Allen said it’s possible that oil could be coming up multiple spaces.

The time needed to kill Macondo will be determined by how many times BP might have to pump mud and cement. Allen said crews might also pump cement into an annulus, allow the cement to harden, and then drill through the hardened cement and go into the wellbore.

Once the flow of oil and gas is completely stopped, cement is pumped into the well to plug the well.

The Development Driller III is drilling the first of the two relief wells. An Apr. 20 explosion on the Deepwater Horizon semisubmersible killed 11 workers. On Apr. 22, the rig sank, and oil spill response crews have been working to stop an ongoing spill.

Weather window expected
Allen said he also has asked BP to provide a detailed timeline outlining the process of replacing an existing lower marine riser package (LMRP) containment cap with another cap that would be bolted onto the failed blowout preventer and that would provide a better seal.

“We are in a lull between tropical weather systems,” Allen said, adding that the next week might provide a good time to replace the containment caps. He has been meeting with BP, and a final decision on whether to replace the caps has yet to be made.

“When we go to the second containment cap, this [LMRP] cap will be taken off and replaced with a cap that is actually bolted to a flange, which will give us a seal and the opportunity to completely control the flow of oil and to produce it or potentially shut in the well,” Allen said.

“The issue is, while we are doing that, we will have to remove the Discoverer Enterprise from its current production position,” Allen said of ongoing oil collection efforts. The Enterprise is a drillship. “That will all require good weather to do that, and a number of days to do that.”

Global LNG: Adjusting to New Realities

Fri, Mar 20, 2015

Oil & Gas Journal’s March 20, 2015, webcast will look at how global LNG trade will be affected over the next 12-24 months by falling crude oil prices and changing patterns and pressures of demand. Will US LNG production play a role in balancing markets? Or will it add to a growing global oversupply of LNG for markets remote from easier natural gas supply? Will new buyers with marginal credit, smaller requirements, or great need for flexibility begin to look attractive to suppliers? How will high-cost, mega-projects in Australia respond to new construction cost trends?

US Midstream at a Crossroads

Fri, Mar 6, 2015

Oil & Gas Journal’s Mar. 6, 2015, webcast will focus on US midstream companies at an inflection point in their development in response to more than 6 years shale oil and gas production growth. Major infrastructure—gas plants, gathering systems, and takeaway pipelines—have been built. Major fractionation hubs have expanded. Given the radically changed pricing environment since mid-2014, where do processors go from here? What is the fate of large projects caught in mid-development? How to producers and processors cooperate to ensure a sustainable and profitable future? This event will serve to set the discussion table for the annual GPA Convention in San Antonio, Apr. 13-16, 2015.

This event is sponsored by Leidos Engineering.

The Future of US Refining

Fri, Feb 6, 2015

Oil & Gas Journal’s Feb. 6, 2015, webcast will focus on the future of US refining as various forces this year conspire to pull the industry in different directions. Lower oil prices generally reduce feedstock costs, but they have also lowered refiners’ returns, as 2015 begins with refined products priced at lows not seen in years. If lower per-barrel crude prices dampen production of lighter crudes among shale plays, what will happen to refiners’ plans to export more barrels of lighter crudes? And as always, refiners will be affected by government regulations, particularly those that suppress demand, increase costs, or limit access to markets or supply.
