largest volume in a year

The stock traded 3.5 million shares yeaterday. I reckon 5-8x average volume. Largest volume since Jan 2002 when their last Turkish wildcat was announced. Before that the largest volumes were related to the first discovery in Turkey.

I'd like to know who is doing the buying. The recent announcements didn't tell us anything we didn't know already except for the G-4, G-5 well delays which isn't exactly good news although hardly unexpected.

Any theories out there?
