Macondo relief well near target; static kill called effective

OGJ Senior Staff Writer

HOUSTON, Aug. 9 – BP PLC, operator of the deepwater Macondo well in the Gulf of Mexico, said the first relief well was at 17,909 ft measured depth on Aug. 9. Crews on Transocean Ltd.’s Development Driller III semisubmersible drilling rig are alternating drilling with ranging runs.

The Macondo well on Mississippi Canyon Block 252 has been shut in since July 15, and there has been no oil flowing into the gulf since then.

“Following the completion of cementing operations on the MC252 well on Aug. 5, pressure testing was performed which indicated there is an effective cement plug in the casing. BP believes the static kill and cementing procedures have been successful,” the company said.

During the static kill on Aug. 4-5, BP stopped the flow of oil and gas from the top of the well by pumping heavy drilling fluid and then cement into the well using the choke lines on the failed blowout preventer of Transocean’s Deepwater Horizon semisubmersible rig.

An Apr. 20 blowout of the Macondo well caused an explosion and fire on the Deepwater Horizon, killing 11 people.

On Aug. 9, National Incident Commander and retired US Coast Guard Adm. Thad Allen told reporters that the relief well was within 30-40 ft of the Macondo wellbore. The ranging runs confirm the relief well’s proximity to the target.

Depending upon weather, Aug. 15 is the estimated date by which the relief well will intercept the MC252 well annulus, BP said. After the intercept, it could take days or weeks to kill the well from the bottom, said Kent Wells, BP vice-president of exploration and production.

A second relief well, being drilled by the Development Driller II, was suspended at 15,874 ft MD so as not to interfere with completion of the first relief well. The second relief well is intended as a backup.

Surface response continues
Work continues to identify and collect oil on the surface of the sea and to collect and clean up oil that has reached shore. Allen said skimming operations recovered more than 826,000 bbl of oily liquid total, and 411 controlled burns have been done on the water’s surface.

Some 30,800 people, more than 5,050 vessels, and dozens of aircraft are engaged in the response effort, Allen said.

BP continues to make claim payments to individuals and businesses. As of Aug. 7, 145,000 claims were submitted, and more than 103,900 payments worth a total of $319 million had been made.

The cost of the response to date amounts to $6.1 billion, including the cost of the spill response, containment, relief well drilling, static kill and cementing, grants to the gulf states, claims paid, and federal costs.

Previously, BP created a $20 billion escrow account to satisfy certain obligations arising from the oil and gas spill.

On Aug. 6, BP appointed Mike Utsler as BP’s lead representative on the Unified Area Command and as chief operating officer for the BP Gulf Coast Restoration Organization. Utsler is a vice-president for BP. His new appointment was effective immediately.

Utsler had served as BP’s commander in its incident command post in Houma, La., since April. Previously, Doug Suttles worked as BP’s representative to the overall response to the spill. Suttles returned to his role in Houston as chief operating officer for BP Exploration & Production.

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.
