Pressure Tests Determine Oil In Annulus; Officials Debate How To Proceed
by Miles Wolf Tamboli - Talk Radio News Service
In a conference call with reporters, Friday, National Incident Commander Thad Allen reported the status of pressure tests on the Macondo deepwater well - the well responsible for the months-long oil spill in the Gulf of Mexico - which resumed Thursday after storms passed through the Gulf.
Allen told reporters that the tests had revealed, “something that is between the annulus and the reservoir that is not allowing the flow of hydrocarbons … the question is, what to do about that moving forward.”
Crews have determined that there may be as much as 1,000 barrels of “stagnant” oil suspended in the well, which could compromise the success of the bottom kill. “Tt remains a work in progress,” said Allen; “we’re trying to assess the options that we have. Everyone is in agreement that we need to proceed with the relief well - the question is how to do that.”
There is a risk that pumping mud and cement into the bottom of the well could increase the pressure beyond the threshold of the machinery now holding the well shut. “To increase the pressure in the blowout preventer and the capping stack in excess of 7,500 PSI would put that link in between them at risk, and we’re trying to figure out what that means and how we could mitigate that risk,” said Allen.
Officials report that they are still wholly committed to completing the relief well and executing the bottom kill, and Allen reported that despite pressure test results showing a possible situation in which conducting a bottom kill could endanger the well’s integrity, BP officials would be “delighted” to show that they could, “drill down over 17,00 feet below sea level and hit a 7-inch pipe.”
“The relief well will be finished, and that is the end result. How it gets finished will be determined on risk mitigation and the way forward that’s being discussed right now. The relief well will be finished - we will kill the well,” Allen concluded. The well will take about 96 hours to complete once drilling has resumed, according to administration officials.
Feds Tightening Rules For Deepwater Drilling
Fewer oil companies will qualify for categorical exclusions under the federal government’s continued moratorium on offshore drilling, said U.S. Department of Interior Secretary Ken Salazar yesterday.
“In light of the increasing levels of complexity and risk, and the consequent potential environmental impacts, associated with deepwater drilling, we are taking a fresh look at the [National Environmental Protection Act] process and the types of environmental reviews that should be required for offshore activity,” Salazar said in a statement.
The actions by the government are intended to redress a loose oversight policy that has allowed many large oil companies to circumvent regulations and receive permits to drill in domestic waters.
A new government report indicated that BP, whose Deepwater Horizon well exploded in the Gulf of Mexico on April 20, killing 11 workers and rupturing a well which spewed millions of gallons of oil into the Gulf for months, directly capitalized on a lax federal review process. The report, published by the White House Council of Environmental Quality, determined that BP was granted permission to drill its deepwater well based on exemptions established by federal regulatory agencies in the 1980’s, several years before the creation of new technologies allowed oil companies to drill a mile below the surface of the ocean.
On Monday, the head of the regulatory agency tasked by President Obama with more or less taking over the job previously performed by the Minerals Management Service (MMS), said increased scrutiny of the oil industry is needed.
“We are building a more robust and aggressive independent oversight agency based on the development of new tools and enhanced legal and regulatory authorities, as well as on the more aggressive use of existing tools,” said Bureau of Ocean Energy Management, Regulation and Enforcement Director Michael Bromwich.
“These changes in our regulatory framework and approach will serve to hold offshore operators accountable and ensure that the industry and the country are fully prepared to deal with catastrophic blowouts and oil spills like the Deepwater Horizon.”
