How much shale gas is there outside the US? It sounds like an impossibly large question, but it is one the US Energy Information Administration has attempted to answer in a new report, carried out by Advanced Resources International.
Their findings are impressive. There is a huge amount of recoverable shale gas out there, says the report – so much that it would add 40 per cent to total global gas supplies. Unsurprisingly the report is already being seized on by gas lobbyists as evidence that shale will change the energy world.
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.
As the oil price continues to soar, taking it to record sterling highs, governments are starting to fret.
In the UK, the chancellor was last month pushed to offer a 1p cut in fuel duty to offset the impact of higher oil prices. The opposition claimed on Tuesday the cut has already been erased by the rise in oil since then, and it is no coincidence that on the same day, the energy secretary Chris Huhne met the Saudis to talk about what can be done on the supply side.
In the US meanwhile, Barack Obama has talked about weaning the country off its oil imports to improve energy security.
