Some days one just gets lucky. Looks like a bunch of people liked GLF. Share price up 35% in one day and nearly 70% for me (I paid $1.35)

Snapshot from Yahoo Finance at close of day Dec 13, 2016.

What happened? Volume was a lot higher than normal (like 4 to 5 times higher). More importantly they are in the middle of a debt restructuring tender and it looks like the tenders are more than they expected. So the debt will almost certainly be restructured. More time for them to trade through the down times.

Now the question on a big run up like this is when to bank the profits? My analysis says these business will continue to profit while oil price rises (provided they do not go bankrupt). When oil price turns over I will close the trade.
