Interesting to see both Parex and PTA down today after Parex's NR. If that is good news, i would hate to see bad news. Possibly one clause in the presentation may have some bearing on the downturn:

 

"The quality of the light oil reserves and a favourable Colombian fiscal regime generate a net present value before tax of $35.76 per barrel for proved plus probable reserves as at December 31, 2012 compared to $ 42.38 per barrel for the prior period. The decrease in the net present value per barrel was primarily a result of increased operating and transportation costs per barrel being reflected in the 2012 evaluation. A 10 percent discount rate was used for the net present value calculations."
