RE:M & AI don't think management is looking to sell the company unless they get a really great offer. Would be fun though if some bigger fish decided to throw out an offer. Might put the company in play and start a bidding war as happened for Suroco.
If there is an offer it might have something to do with the new transportation routes. Putumayo was always a very prolific area with a big time transportation bottleneck that could cause production to get shut in. WIth those concerns mostly gone, bigger players know that the region is going to be producing a lot more oil in a few years.
