Many thanks for all your questions for Amrita Sen, oil analyst at BarCap. Her answers will appear on this site on Friday, April 8th.
Next week, the person in the hotseat will be Michael Bromwich, director of the US oceans regulator, the Bureau of Ocean Energy Management, Regulation and Enforcement.
Bromwich is the person in charge of deciding who gets to drill where in the sea off the US, and one year on from the BP oil spill, this is your chance to quiz him on everything from who should be able to drill in the Gulf of Mexico to what can be done to prevent another major spill.
Email all your questions to firstname.lastname@example.org by Monday, April 11th.
