As of Tue, Aug 17, 2010 BP is on standby to get government approval to drill final 50 feet to intersect MC252 well annulus (space between rock formation and well casing) at about 800 feet above oil reservoir.
Below are quotes from BP’s briefing with Kent Wells on sealing Macondo well (Aug 10, 2010):
“We do know that we pumped about 200 barrels of cement or so out of the casing. Did it go into the reservoir? Did some go into the reservoir? Did some go up in the annulus? That’s an unknown.”
“We’re planning to intersect the well about 800 feet above the reservoir. And where we are right now with the relief well, we’re just at the shoe of the outer casing. And so we’re now going to start to go down to the place where we can intersect the annulus. And the annulus we’re describing is the annulus between the casing of the Macondo well and just the rock formation. It’s not an annulus between casing and casing. We’re going to intersect it at a point where it’s basically rock and then there’s an annulus and then there’s casing. And that’s where we plan to intersect.”
“And what we don’t know is exactly what we’ll find in that annulus. It could be mud. It could be oil. It could be cement. We just don’t know.”

BP: LMRP cap collected 11,100 barrels in 24 hours; remaining oil is still spilled into the Gulf. BP will provide rate of collection every 12 hours starting June 7.
Currently preparing two backup setups, to be introduced in mid June (choke and kill lines suction) and end of June (submerged riser)

- Collapsed riser cutting is underway
- LMRP cap is scheduled for connection the Week of May 31 (temporary solution)
- Choke and Kills lines will be connected to a second LMRP to divert some of oil & gas flow (scheduled for second half of June 2010)
- BP is preparing a floating subsurface riser for hurricane emergency shut off (long term solution)
- Relief wells’ drilling is in progress, will be completed in August.
